A description of Lynx +can be found in the README file. Lynx has been ported to UN*X, VMS, Win32 +and 386DOS. The procedures for compiling these ports are quite divergent +and are detailed respectively in Sections II, III, IV and V. General +installation, problem solving and environment variables are covered in +Sections VI and VII. There is also a PROBLEMS file in the same directory +as INSTALLATION which contains advice for special problems people have +encountered, especially for particular machines and operating systems. + +If you still have difficulties, send an e-mail message to the Lynx-Dev mailing +list (see the README file). Try to include information about your system, +the name and version of your compiler, which curses library you are using +and the compile-time errors. Be sure to say what version and image-number +of Lynx you are trying to build (alternately the top date of the CHANGES file). + +If you don't understand what one of the defines means, try the README.defines +and *.announce files in the docs subdirectory. The docs/CHANGES* files record +the entire development history of Lynx and are an invaluable resource for +understanding how Lynx should perform. + +First, you must configure Lynx for your system regardless of the port you use. +Follow the instructions given immediately below to configure for your system, +and then go to the respective section concerning the port you wish to compile. + +------------------------------------------------------------------------------- + +I. General configuration instructions (all ports). + +Step 1. Compile-time Variables. + + There are a few variables that MUST be defined if Lynx is to build + and there are others you may want to change. + + Lynx MUST be able to find lynx.cfg at start-up: using configure + (e.g. with UNIX or Cygwin), its location is best set with --sysconfdir ; + you can check in lynx_cfg.h after configure has run, if you wish. + otherwise, you can use LYNX_CFG_FILE in userdefs.h , + environment variable LYNX_CFG or the -cfg command-line option. + + If you are using configure, you need not make any changes in userdefs.h . + There are a few variables you can't define with configure --options + but can define in userdefs.h , e.g. numbering fields as well as links. + Many variables which can be defined with configure or userdefs.h + can also be defined in lynx.cfg or via the Options Menu. + + Lynx implements Native Language Support. Read "ABOUT-NLS", if you want + to build an international version of Lynx or tailor status-line prompts, + messages and warnings to the requirements of your site. + +Step 2. Run-time Variables. + + Read lynx.cfg thoroughly, as many Lynx features and how to use them + are explained there, in some cases ONLY there. Set up local printers, + downloaders, assumed character set, key mapping and colors in lynx.cfg . + Also see the sample mime.types, mailcap and jumps files + in the samples subdirectory. + +Step 3. Alternative Character Sets. + + You may skip this, if you are not interested in special characters + and all local files or WWW pages you will view will use the ISO-8859-1 + "ISO Latin 1" Western European character set. + + If you will be running Lynx in an environment with different incompatible + character sets, configure CHARACTER_SET (the Display character set) + and ASSUME_LOCAL_CHARSET to work correctly before creating bookmark files + and other such items: read lynx.cfg for detailed instructions. + Additional character sets and their properties may be defined with tables + in the src/chrtrans directory: see the README.* files therein. + +Step 4. News. + + Set NNTPSERVER in lynx.cfg to your site's NNTP server + or set the environment variable externally. For posting to be enabled, + NEWS_POSTING must be TRUE in userdefs.h or lynx.cfg. + Also define LYNX_SIG_FILE in userdefs.h or lynx.cfg , + so that it points to users' signature files for appending to messages. + +Step 5. Anonymous Accounts *** VERY IMPORTANT!!!!! *** + + If you are building Lynx for personal use only, you can skip this. + + If you are setting up anonymous accounts to use Lynx captively, + i.e. making Web access publicly available to users who should not + be allowed any other type of access to your system, + you are STRONGLY advised to use the -anonymous command-line option: + if you do not use this option, users may be able to gain access + to all readable files on your machine! + + Many implementations of telnetd allow passing of environment variables, + which might be used to modify the environment in anonymous accounts, + allowing mischief or damage by malicious users, so make sure the wrapper + uses the -cfg and -homepage switches to specify lynx.cfg and start-file, + rather than relying on variables LYNX_CFG, LYNX_CFG_FILE and WWW_HOME. + +------------------------------------------------------------------------------- + +II. Compile instructions -- UNIX + +1a. Auto-configure. The auto-configure script uses autoconf2.13 to generate a + Bourne shell script, configure, which creates "makefile" and "lynx_cfg.h". + + If you are on a UNIX platform, the easiest way to build Lynx is to type: + + ./configure + and + make + + NOTE: Configure has a number of useful options. Please see below. + + NOTE: The 'configure' script generates auxiliary files "config.status" + "config.cache" and "config.log". Normally you will not notice these; + they are created automatically and removed by a "make distclean". + + + If you wish to rebuild Lynx with a new host, or change ANY of the + parameters which are stored in config.cache, you MUST first remove + the config.cache file before running configure; its options do NOT + override the settings in that file. + + + The config.status file is a script which creates (or regenerates) + the files created by the configure script. + + Please report problems in the configure/make process by including a copy + of config.status, config.cache and config.log, as well as the pertinent + compiler diagnostics. + + See the note in aclocal.m4 for special instructions if you must modify the + configure script. + + NOTE: Lynx is a curses-based application, so you must have a curses + library available to link to. Native curses (on the system when it was + installed) are often broken, so you may get superior performance if you + have either + + "ncurses" ("https://invisible-island.net/ncurses") or + "slang" ("ftp://space.mit.edu/pub/davis/slang"). + + If you install these libraries in your home directory or a non-default + location, you may need to set the CPPFLAGS (full path to include files) and + LIBS (full path to library files) environment variables BEFORE running + configure. See "1d. Environment". Use the "--with-screen=ncurses" or + "--with-screen=slang" option. + + Note that while lynx will build with a variety of versions of curses and + ncurses, some will be less satisfactory. Versions of ncurses before + 1.9.9g will not render color properly. Some other versions of curses do + not display color at all. Likewise, lynx may not build with old versions + of slang, e.g., before 0.99-38, because slang's interfaces change + periodically. + + Note compiler/system specific problems below. See also: + https://invisible-island.net/ncurses/ncurses.faq.html + +1b. Platforms. Configure should work properly on any Unix-style system. + It has been tested on the following platforms. + + AIX 3.2.5 (cc w/ curses) BeOS 4.5 (gcc w/ ncurses) + CLIX (cc w/ curses & ncurses) DGUX + Digital Unix 3.2C and 4.0 (gcc & cc w/ curses, ncurses & slang) + FreeBSD 2.1.5, 3.1 (gcc 2.6.3 w/ curses & ncurses) + HP-UX (K&R and ANSI cc, gcc w/ curses, ncurses & slang) + IRIX 5.2 and 6.2 (cc & gcc w/ curses, ncurses & slang) + Linux 2.0.0 (gcc 2.7.2 w/ curses, ncurses & slang) + MkLinux 2.1.5 (gcc 2.7.2.1) NetBSD + NEXTSTEP 3.3 (gcc 2.7.2.3 w/ curses) + OS/2 EMX 0.9c (ncurses) SCO OpenServer (cc w/ curses) + Solaris 2.5, 2.6 & 2.7 (cc & gcc w/ curses, ncurses & slang) + SunOS 4.1 (cc w/ curses, gcc w/ ncurses & slang) + OS390 and BS2000. + + NOTE: SunOS and HP-UX come with a bundled K&R compiler, which is only + useful for compiling with the bundled curses. Both ncurses and slang + require a compiler that recognizes prototypes. + +1c. Options + To get a list of the configure script's options, type "./configure --help". + Below is an alphabetical listing of the Lynx-specific options. The actual + order shown by the -help option is different. See "docs/README.defines" + for information on defines for which there are no option switches. + + --datadir + Defines the location where you want the documentation files installed. + The configure script constructs makefile actions to install lynx.cfg + modified to reflect this in the HELPFILE setting. (For platforms which + do not support a configure script, such as MS-DOS, Win32 and VMS, you + must edit lynx.cfg). + + --disable-addrlist-page (prevent defining USE_ADDRLIST_PAGE) + Turn off code that displays an alternative list-page, bound to 'A' + rather than 'l', which always lists URLs rather than titles. + + --disable-alt-bindings (prevent defining USE_ALT_BINDINGS) + Compiles-in an alternative set of line-edit bindings, in addition + to the default bindings. + + --disable-bibp-urls (define DISABLE_BIBP) + Disable (do not compile code) support for bibp: URLs. + + --disable-cjk (define CJK_EX) + Disable logic for supporting CJK documents. + + --disable-color-style (define USE_COLOR_STYLE) + Use this option to disable optional color style. This is implemented + for modern curses implementations, e.g., those that support color. + + Before lynx 2.8.6dev.18, this option was disabled by default. + You can achieve a similar color effect to match the non-color-style + (but still allowing users to use color-style) by using the + --without-lss-file option. + + --disable-config-info (define NO_CONFIG_INFO) + Use this option to disable extended browsable configuration information + (a screen that shows the result of the configuration script, as well + as extended lynx.cfg viewing with a pointer to the lynx.cfg file and + additional functionality). + + --disable-dired (prevent defining DIRED_SUPPORT) + Use this option to disable the optional directory-editor. + + Lynx supports directory editing (DirEd) for local directories. + This allows users to do things like view, copy and remove files + using a tabular display of the directory and single-keystroke + commands instead of using the command line. From inside Lynx, the + keystroke sequence "g.<enter>" switches Lynx to DirEd mode on the + current directory. If you're building a Lynx that is to be used as + a kind of restricted shell for users who do not have access to the + command line and should not have access to equivalent capabilities, + you probably want to disable DirEd with this option. You can also + disable some DirEd functions while allowing others. If you have + disabled DirEd completely, you can ignore all the more specific + DirEd options. + + All DirEd menu functions that were enabled on compilation can be + disabled or modified at run time via DIRED_MENU symbols in lynx.cfg. + + --disable-dired-dearchive (define ARCHIVE_ONLY) + Use this option to prevent DirEd from extracting files from an + archive file. + + --disable-dired-gzip (prevent defining OK_GZIP) + Use this option to prevent DirEd from using gzip and gunzip. + + --disable-dired-override (prevent defining OK_OVERRIDE) + Normally, in DirEd directory viewing mode some key mappings are + overridden. Use this option to disable DirEd keymap overriding. + + --disable-dired-permit (prevent defining OK_PERMIT) + Use this option to prevent DirEd from changing the permissions + on directories or files (i.e., from doing what the Unix chmod + command or the DOS attrib command does). + + --disable-dired-tar (prevent defining OK_TAR) + Use this option to prevent DirEd from using the tar program. + + --disable-dired-uudecode (prevent defining OK_UUDECODE) + Use this option to prevent DirEd from using uudecode. + + --disable-dired-xpermit (define NO_CHANGE_EXECUTE_PERMS) + Use this option if you do not disable out the dired-permit + option, but want to restrict changes of the eXecute permission + to directories (i.e., not allow it to be changed for files). If + you don't do this, you can still block changes of the eXecute + permission for files but not directories via the + "change_exec_perms" command line restriction. + + --disable-dired-zip (prevent defining OK_ZIP) + Use this option to prevent DirEd from using zip and unzip. + + --disable-echo + Use this option to suppress the "compiling" commands during a build. + Doing this makes it easier to find and read warning messages. + + --disable-extended-dtd (define NO_EXTENDED_HTMLDTD) + disable extended HTML DTD logic. This should revert to old-style + (2.7.1/2.7.2) behavior, but is not well-tested. + + --disable-file-upload (define USE_FILE_UPLOAD) + Compile-in support for form-based file-upload. + + --disable-finger (define DISABLE_FINGER) + Do not compile-in code used to connect to "finger" URLs. + + --disable-forms-options (define NO_OPTION_FORMS) + Disable the Form-based Options Menu (see --disable-menu-options). + The default is to compile key-based & form-based Options Menu code, + allowing users the final choice via FORMS_OPTIONS in lynx.cfg + or the -forms_options command-line switch. + + --disable-ftp (define DISABLE_FTP) + Do not compile-in code used to connect to FTP servers. + + --disable-full-paths + Use this option to control whether full pathnames are compiled in for + various utilities invoked by lynx as external commands. By default, + full pathnames are compiled in for the the locations where configure + finds these commands at configure time. + + Affected commands include + chmod compress cp gzip install mkdir mv rm tar touch gunzip + unzip brotli bzip2 uudecode zcat zip telnet tn3270 rlogin + (Not all commands are used on all systems or in all configurations.) + + This option makes Lynx simpler to install, but potentially less secure, + since the commands are then set in the user's $PATH. All of these + commands may also be overridden individually by setting environment + variables before configuring. For example, you can disable the telnet + command by doing this: + + setenv TELNET /bin/false + + --disable-gopher (define DISABLE_GOPHER) + Do not compile-in code used to connect to GOPHER servers. + + --disable-idna + By default, the configure script searches for the GNU idn library, + which lets lynx translated URLs which are in UTF-8 to ASCII. The + latter is needed for most network accesses. Use this option to + suppress the feature, e.g., to reduce size. + + --disable-included-msgs + Do not use included messages, for i18n support. If NLS support is + requested, the configure script will otherwise use the messages in the + ./po subdirectory. + + --disable-japanese-utf8 (define USE_JAPANESEUTF8_SUPPORT) + use Japanese UTF-8 logic, which uses iconv to convert pages with + charset euc-jp, shift_jis to utf-8. + + --disable-justify-elts (define USE_JUSTIFY_ELTS) + Do not use element-justification logic. + + --disable-largefile (prevent defining LONG_LIST) + + Use this option to disable the compiler and linker options that + provide largefile interfaces. + + --disable-locale-charset (define USE_LOCALE_CHARSET) + Use nl_langinfo(CODESET) to determine initial value for display + charset, overrides character_set value in .lynxrc file. + + --disable-long-list (prevent defining LONG_LIST) + Use this option to disable long "ls -l" directory listings (when + enabled, the actual directory style is configurable from lynx.cfg). + + --disable-menu-options (define NO_OPTION_MENU) + Disable the Key-based Options Menu. + See --disable-forms-options (above) for further details. + + --disable-news (define DISABLE_NEWS) + Do not compile-in code used to connect to NNTP (netnews) servers. + + --disable-parent-dir-refs (define NO_PARENT_DIR_REFERENCE) + Use this option to disable "Up-to" parent-links in directory listings. + + --disable-partial (prevent defining DISP_PARTIAL) + Turn off code that lets Lynx display parts of a long page while loading + it. + + --disable-persistent-cookies (prevent defining USE_PERSISTENT_COOKIES) + Turn off support for saving cookies to a file, for subsequent reuse. + Persistent cookie support will use (or create) the file specified by + the 'COOKIE_FILE' option, or default to ".lynx_cookies" in the home + directory. (Currently there is no protection against conflict if + several lynx sessions are active from the same account). + + --disable-prettysrc (define USE_PRETTYSRC) + Turn off support for colorizing the source view of HTML pages. If + compiled-in, new source view mode is available with -prettysrc command + line option. + + --disable-progressbar (define USE_PROGRESSBAR) + Turn off support for a "progress bar" which displays at the bottom + of the screen when doing downloads and other time-consuming (but + interruptible) processes. This feature can be selected in the + options menu. + + --disable-read-eta (define USE_READPROGRESS) + Turn off enhanced read-progress message showing ETA (estimated time to + completion), as well as the amount of time stalled without any data + transferred. + + --disable-rpath-hack + The rpath-hack makes it simpler to build programs, particularly with + the *BSD ports which may have essential libraries in unusual places. + But it can interfere with building an executable for the base system. + Use this option in that case. + + --disable-scrollbar (define USE_SCROLLBAR) + Turn off support for scrollbar on the right-margin of the screen. + If you configure with ncurses, this works with the mouse on xterm, + etc. + + --disable-session-cache (define USE_CACHE_JAR) + Turn off support for saving/restoring session information in files. + Configurable from lynx.cfg + + --disable-sessions (define USE_SESSIONS) + Turn off support for sessions, which allows the user to automatically + save and restore history information. + + --disable-source-cache (define USE_SOURCE_CACHE) + Turn off support for caching HTML pages locally, + in files or in memory. Configurable from lynx.cfg + + --disable-trace (define NO_LYNX_TRACE) + Turn off code that lets you trace internal details of Lynx's operation. + We recommend that you leave this enabled, since we need this + information to diagnose problems with either Lynx or the sites to which + you connect. + + --enable-ascii-ctypes (define USE_ASCII_CTYPES) + Compiles-in alternative case-conversion functions which ensure that + configuration names, etc., are compared in POSIX locale. This is + important for operating in some locale such as Turkish. + + --enable-cgi-links (define LYNXCGI_LINKS) + Allows lynx to access a cgi script directly without the need for + a http daemon. + + --enable-change-exec (define ENABLE_OPTS_CHANGE_EXEC) + Allow users to change the execution status within the options screen. + See EXEC_LINKS and EXEC_SCRIPTS. + + --enable-charset-choice (define USE_CHARSET_CHOICE) + Add logic for ASSUMED_DOC_CHARSET_CHOICE and DISPLAY_CHARSET_CHOICE in + lynx.cfg, allowing user to configure a subset of the compiled-in + charsets for normal use. + + --enable-chinese-utf8 (define EXP_CHINESEUTF8_SUPPORT) + use Chinese UTF-8 logic, which uses iconv for converting pages with + charset gb2312 (aliased to euc-cn), big5 to utf-8. The Korean charset + euc-kr happens to work with this setting. + + --enable-debug (The symbol DEBUG is always defined.) + Use this option to compile-in support for debugging. + Note that this flag is ignored if the CFLAGS environment + variable is set, in that case "-g" (or whatever) has to + be included in the CFLAGS value to get debugging. + Autoconf normally adds -g and -O options to CFLAGS if CFLAGS + was not set, and if the compiler supports those options. + + --enable-default-colors (define USE_DEFAULT_COLORS) + Enable use of default-color background (ncurses/slang). Either + configuration supports the use of 'default' for colors even without + this option. That is, 'default' is interpreted as white (foreground) + or black (background) according to the context. When the default + colors configuration is built, the actual values for foreground and + background colors are determined by the terminal. + + --enable-exec-links (define EXEC_LINKS) + Allows lynx to execute programs by accessing a link. + + --enable-exec-scripts (define EXEC_SCRIPTS) + Allows lynx to execute programs inferred from a link. + + --enable-externs (define USE_EXTERNALS) + Use this option to enable external application support. (See lynx.cfg.) + + --enable-find-leaks (define LY_FIND_LEAKS) + Use this option to compile-in logic for testing memory leaks. + + --enable-font-switch (define EXP_CHARTRANS_AUTOSWITCH) + Allow Lynx to automatically change the Linux console state (switch + fonts) according to the current Display Character Set. (Linux console + only. *Use with discretion.* See docs/README.chartrans.) + + --enable-gnutls-compat (define USE_GNUTLS_FUNCS) + When --with-gnutls is used, tell whether to use GNUTLS's OpenSSL + compatibility library or use GNUTLS's low-level API directly. + + --enable-gzip-help + Install the lynx help files in gzip'd format [*.gz] to save space. + + --enable-htmlized-cfg + generate an HTMLized copy of lynx.cfg which will be installed with + the other help files. + + --enable-internal-links (define TRACK_INTERNAL_LINKS) + With `internal links' (links within a document to a location within + the same document) enabled, Lynx will distinguish between, for example, + `<A HREF="foo#frag">' and `<A HREF="#frag">' within a document whose + URL is `foo'. It may handle such links differently, although practical + differences would appear only if the document containing them resulted + from a POST request or had a no-cache flag set. This feature attempts + to interpret URL-references as suggested by RFC 2396, and to prevent + mistaken resubmissions of form content with the POST method. An + alternate opinion asserts that the feature could actually result in + inappropriate resubmission of form content. + + --enable-ipv6 (define ENABLE_IPV6) + use IPV6 (with IPV4) logic. + + --enable-kbd-layout (define EXP_KEYBOARD_LAYOUT) + Disabled by default, this option allows you to use translation + tables on the input keystrokes. Current tables include + ROT13'd keyboard layout + JCUKEN Cyrillic, for AT 101-key kbd + YAWERTY Cyrillic, for DEC LK201 kbd + + --enable-local-docs + On install, modify link from help-page to point to the local + doc-directory, e.g., with README files. Normally this points + to the current release directory. + + --enable-nested-tables (define EXP_NESTED_TABLES) + Extends TRST to format nested tables, as well as be smarter about + <BR> and <P> tags in table cells. + + --enable-nls (several definitions) + use Native Language Support (i.e., gettext). + + This relies upon external programs (msgfmt and xgettext) to format + the message catalogs: + + + Unless you set the environment variables MSGFMT and XGETTEXT to + the full pathnames of these utilities, the configure script will + search for the GNU versions of these utilities. + + It will also search for the GNU version of the corresponding + gettext() runtime function. On some platforms (such as Solaris), + this search gives misleading results. + + + If you set those environment variables to full pathnames, the + configure script will warn if they are not the GNU versions of + the utilities. + + --enable-nsl-fork (define NSL_FORK) + Disabled by default, this allows interruption of NSL requests, + so that `z' will stop the `look-up' phase of a connection. + + --enable-stdnoreturn (define HAVE_STDNORETURN_H) + Check for C11 _Noreturn feature, using that rather than gcc-specific + __attribute__((noreturn)), to improve compiler diagnostics. + + --enable-syslog (define SYSLOG_REQUESTED_URLS) + Use this option to log NSL requests via syslog(). + + --enable-underlines (define UNDERLINE_LINKS) + Use this option to underline links rather than using boldface. + + --enable-vertrace (define LY_TRACELINE) + Turn on code that prefixes trace output lines with source filename + and line number. + + --enable-warnings + Use this option to turn on GCC compiler warnings. + + --enable-wais + Use this option to turn on configure check for freeWAIS library. + + --enable-wcwidth-support (define EXP_WCWIDTH_SUPPORT) + use experimental wcwidth/UTF-8 logic. + + --enable-widec + Use this option to allow the configure script to look for wide-curses + features. If you do not specify the option, the configure script + will look for these features if --with-screen=ncursesw is given. + For this release of Lynx, we recommend the ncursew library built from + ncurses 5.5. + + --sysconfdir (affect LYNX_CFG_FILE) + Defines the location where you want the lynx.cfg file installed. + The configure script defines the symbol LYNX_CFG_FILE to correspond + with the $sysconfdir environment variable. (For platforms which do not + support a configure script, such as MS-DOS, Win32 and VMS, you must + edit userdefs.h if you wish to specify the location of lynx.cfg). + + --with-Xaw3d + This option allows you to specify the X libraries used if you + are configuring lynx to use PDCurses on a Unix platform. + + --with-XawPlus + This option allows you to specify the X libraries used if you + are configuring lynx to use PDCurses on a Unix platform. + + --with-brotli[=XXX] (define USE_BROTLI) + Use brotli decompression. + + The optional value XXX specifies the directory in which the library + can be found, and may be either the path of the "lib" directory, + or one level above. In either case, the corresponding header files + are assumed to be in the parallel "include" directory. + + --with-build-cc=XXX + If cross-compiling, specify a host C compiler, which is needed to + compile a utility which generates tables for lynx. + If you do not give this option, the configure script checks if the + $BUILD_CC variable is set, and otherwise defaults to gcc or cc. + + --with-build-cpp=XXX + This is unused by lynx. + + --with-build-cflags=XXX + If cross-compiling, specify the host C compiler-flags. You might need + to do this if the target compiler has unusual flags which confuse the + host compiler. + + --with-build-cppflags=XXX + If cross-compiling, specify the host C preprocessor-flags. You might + need to do this if the target compiler has unusual flags which confuse + the host compiler. + + --with-build-ldflags=XXX + If cross-compiling, specify the host linker-flags. You might need to + do this if the target linker has unusual flags which confuse the host + compiler. + + --with-build-libs=XXX + If cross-compiling, the host libraries. You might need to do this if + the target environment requires unusual libraries. + + --with-bzlib[=XXX] (define USE_BZLIB) + Use libbz2 for decompression of some bzip2 files. + + The optional value XXX specifies the directory in which the library + can be found, and may be either the path of the "lib" directory, + or one level above. In either case, the corresponding header files + are assumed to be in the parallel "include" directory. + + --with-charsets=list (define ALL_CHARSETS) + Limit the number of charsets that are compiled-in to the specified + list of comma-separated MIME names. + + --with-cfg-file (define LYNX_CFG_FILE) + Specify the default configuration file's name. Use --without-cfg-file + to force the user to specify the configuration file on the command + line. The filename can be overridden by using the LYNX_CFG environment + variable. + + --with-cfg-path (define LYNX_CFG_PATH) + Specify the default configuration file(s) directory search-list. Use + --without-cfg-path to limit this to the location of the lynx.cfg file. + The search-list can be overridden using the LYNX_CFG_PATH environment + variable. + + --with-curses-dir + Specify directory under which curses/ncurses is installed. This + assumes a standard install, e.g., with an include and lib subdirectory. + + --with-dbmalloc + use Conor Cahill's dbmalloc library + + --with-destdir=XXX + set DESTDIR variable in makefiles. This is prefixed to all directories + in the actual install, but is not really part of the compiled-in or + configured directory names. It is convenient for packaging the + installed files. If you do not provide the option, the configure + script uses your $DESTDIR environment variable. + + --with-dmalloc + use Gray Watson's dmalloc library + + --with-gnutls[=XXX] (define USE_SSL, USE_GNUTLS_INCL) + Use this option to configure with the GNU TLS library. + See docs/README.ssl for additional information. + + The optional value XXX specifies the directory in which the library + can be found, and may be either the path of the "lib" directory, + or one level above. In either case, the corresponding header files + are assumed to be in the parallel "include" directory. The default + is /usr/local/gnutls. + + See the "--enable-gnutls-compat" option. + + --with-included-gettext + not supported in this package. The configure script uses macros which + are bundled together with more useful features. + + See the "--enable-nls" option. + + --with-libiconv-prefix=DIR + search for libiconv in DIR/include and DIR/lib + + --with-lss-file{=path} (define LYNX_LSS_FILE) + Specify the default style-sheet file's name. Use --without-lss-file + to make the default behavior match the non-color-style (if no --lss + option is given, and no COLOR_STYLE setting is in lynx.cfg). + + --with-mime-libdir=list (define MIME_LIBDIR) + Use this option to specify the system directory containing the + mime.types and mailcap files. + + --with-neXtaw + This option allows you to specify the X libraries used if you + are configuring lynx to use PDCurses on a Unix platform. + + --with-nls-datadir=DIR + Use this option to override the configure script's NLS data directory, + under which the locale (i.e., language) files are installed. The + default value is derived at configure time, and depends on whether GNU + or native gettext is used. + + --with-nss-compat[=XXX] (define USE_NSS_COMPAT_INCL) + Use this option to configure with the NSS library's OpenSSL-compatible + interface. + See docs/README.ssl for additional information. + + The optional value XXX specifies the directory in which the library + can be found, and may be either the path of the "lib" directory, + or one level above. In either case, the corresponding header files + are assumed to be in the parallel "include" directory. + + --with-pkg-config[=XXX] + Use pkg-config, if available, to tell how to build with certain + libraries, e.g., openssl and gnutls. If pkg-config is not used, + or if those libraries are not known to pkg-config, then the configure + script will search for the libraries as described in the --with-ssl + and --with-gnutls options. + + The optional value XXX specifies the pathname for pkg-config, e.g., + "/usr/local/bin/pkg-config". + + Note: The pkg-config program is used only if no explicit directory + parameter is provided for the --with-ssl or --with-gnutls options. + + --with-screen=XXX + Use this option to select the screen type. The option value, XXX + must be one of curses (the default), ncurses, ncursesw, pdcurses or + slang. Specifying a screen type causes the configure script to + look in standard locations for the associated header and library + files, unless you have preset the $CFLAGS and $LIBS variables. + + --with-screen=ncursesw (define NCURSES, WIDEC_CURSES) + --with-screen=ncurses (define NCURSES) + --with-screen=pdcurses (define PDCURSES) + --with-screen=slang (define USE_SLANG) + + Note that some systems may have a default curses library which + does not support color, while on others, ncurses is installed as + the curses library. The variant ncursesw is the wide-character + version of ncurses. See also the --enable-widec option. + + For the ncurses/ncursesw options, the script also accepts variants + such as "ncursesw6", which helps it to find a specific ncurses config + script. + + The pdcurses selection supported by the configure script is a UNIX-only + library which uses X11. If you are configuring with DJGPP, the likely + choice is "curses", since that is how PDCurses is normally installed. + + --with-socks[=XXX] (define SOCKS) + Use this option to configure with the socks library. + + The optional value XXX specifies the directory in which the library + can be found, and may be either the path of the "lib" directory, + or one level above.

In either case, the corresponding header files + are assumed to be in the parallel "include" directory. + + If you make a SOCKSified lynx, you may have trouble accessing FTP + servers. Also, instead of SOCKSifying lynx for use behind a firewall, + you are better off if you make it normally, and set it up to use a + proxy server. You can SOCKSify the proxy server, and it will handle + all clients, not just Lynx. If you do SOCKSify lynx, you can turn off + SOCKS proxy usage via a -nosocks command line switch. + + --with-ssl[=XXX] (define USE_SSL) + Use this option to configure with the OpenSSL library, or SSLeay. + See docs/README.ssl for additional information. + + The optional value XXX specifies the directory in which the library + can be found, and may be either the path of the "lib" directory, + or one level above.

In either case, the corresponding header files + are assumed to be in the parallel "include" directory. + +1d. Environment variables + The configure script looks for programs and libraries in known/standard + locations. You can override the behavior of the script by presetting + environment variables. If they are set, the script will try to use these + values rather than computing new ones. Useful variables include: + + CC - the C compiler. If you do not override this, configure + will try to use gcc. For instance, setting CC=cc and + exporting this value will cause configure to use cc instead. + + CFLAGS - the C compiler options. These also include C + preprocessor options (such as -I), since the $CFLAGS and + $CPPFLAGS variables are maintained separately. + + CPPFLAGS - the C preprocessor options. For some configuration + tests, you may need to set both $CFLAGS and $CPPFLAGS if + you are compiling against header files in nonstandard + locations. + + LDFLAGS - linker/loader options. + + LIBS - the libraries to be linked, with -L and -l options. If + you are linking against libraries in nonstandard locations + unrelated to the install prefix (that you can specify in + the configure script) you may have to specify these via + the $LIBS variable. + + Lynx has compiled-in the pathnames of various programs which it executes. + Normally the full pathnames are given, rather than the program name + alone. These may be preset in the environment by the capitalized version, + e.g., INSTALL for "install". The corresponding internal definitions + are suffixed "_PATH", e.g., "INSTALL_PATH". + + +-- 1997/7/27 - T. Dickey <dickey@clark.net> + +1e. Examples + If you are compiling Lynx for your personal use and are restricted to your + home directory, a simple method for building would be to choose some + directory, say ".lynx", and then type: + + ./configure --prefix=~/.lynx --exec-prefix=~/.lynx + and + make install + + Now you only need to add "~/.lynx/bin" to your PATH and edit "~/.lynx/lib/ + lynx.cfg" as described above. + + I personally use the following csh shell script to set environment + variables and configure options rather than type them each time. + #!/bin/csh -f + setenv CPPFLAGS "-I$HOME/slang -I$HOME/.usr/include" + setenv LIBS "-L$HOME/.slang/lib -L$HOME/.usr/lib" + ./configure --exec-prefix=$HOME --bindir=$HOME/.lynx \ + --mandir=$HOME/.usr/man --sysconfdir=$HOME/.usr/lib \ + --with-screen=slang --with-zlib + + CPPFLAGS in this example defines the full path to the slang and zlib + header files, which are not kept in standard directories. Likewise, LIBS + defines the nonstandard locations of libslang.a and libz.a. Setting the + option --bindir tells the configure script where I want to install the + lynx binary; setting --mandir tells it where to put the lynx.1 man page, + and setting --sysconfdir tells it (while at the same time defining + LYNX_CFG_FILE) where to put the configuration file "lynx.cfg", when I type + "make install". The --with-screen=slang and --with-zlib options are + explained above. + +2. Wais support (optional) + To add direct WAIS support, get the freeWAIS distribution from + "ftp://ftp.cnidr.org/pub/NIDR.tools/freewais", and compile it. The + compile process will create the libraries you will need, wais.a and + client.a. Edit the Makefile in the top level directory and add the + library locations under the DIRECT WAIS ACCESS heading. Edit the Makefile + for the WWW Library in "WWW/Library/Implementation/makefile" to point to + the include directory for the freewais distribution. Precompiled + libraries are available for many platforms if you don't wish to compile + one yourself. + +------------------------------------------------------------------------------- + +III. Compile instructions -- VMS + +Step 1. Downloading binary files. + Lynx must handle all IO as streams, and on VMS, output files are always + created with Stream_LF format via the C RTL's fopen(). The file headers + indicate Implied Carriage Control, even when the transfer was in binary + mode, which can confuse downloading software and cause corruption of + the file contents. To deal with this, you should define the symbol + USE_FIXED_RECORDS as TRUE in userdefs.h and/or lynx.cfg. This will + instruct Lynx to correct the header information to indicate FIXED 512 + records, with No Implied Carriage Control. If Lynx fails to do the + conversion (because the file wasn't mapped to a binary MIME type) you can + execute FIXED512.COM externally to correct the header information. The + command file uses Joe Meadow's FILE utility, or the SET FILE/ATTRIBUTES + command on current versions of VMS, to modify the headers. See the + comments in FIXED512.COM, userdefs.h and lynx.cfg for more information. + +Step 2. Passive FTP + If your system requires the PASV FTP code instead of the standard PORT FTP + code (e.g., to deal with a firewall) then set the FTP_PASSIVE option in + lynx.cfg + +Step 3a. + Lynx uses the VMS port of gzip for uncompressing streams which have + Content-Encoding headers indicated compression with gzip or the + Unix compress. If you do not have gzip installed on your system + you can get it from "ftp://ftp.wku.edu/" in the fileserv directory. + The command Lynx uses to uncompress on VMS is "gzip -d". + + If you are using the SOCKETSHR library, read SOCKETSHR.announce and + make sure you have defined SOCKETSHR and SOCKETSHR_LIBRARY as explained + therein. + + A "build.com" and "build-slang.com" script for building Lynx with curses + or slang is in the top level directory. All you have to do is type + "@build" or "@build-slang" and answer its prompt for your system's TCP-IP + software. Current choices are: + MULTINET (default) + UCX + WIN_TCP + CMU_TCP + SOCKETSHR_TCP + TCPWARE + It will autosense whether you have VAXC, DECC or GNUC on VAX or AXP and + build appropriately. If a WWWLib already exists for that TCP-IP software, + it will prompt you for whether you want to rebuild it. If you want to + build a WWWLib separately, you can type "@libmake.com" with your default + directory set to [.WWW.Library.vms] instead doing it via "build.com" in + the top directory. You may need to modify "build-slang.com", as described + in its header, so that it can find slang.olb on your system. If you have + both DECC and VAXC, it will use DECC to benefit from the newer and more + efficient memory management functions. + +Step 3b. (optional compilation method) + If you have and want to use MMS, read the header of descrip.mms in the + top directory and be sure you include the appropriate macro definitions + when you invoke it: + + $ MMS /Macro = (MULTINET=1) for VAXC - MultiNet + $ MMS /Macro = (WIN_TCP=1) for VAXC - Wollongong TCP/IP + $ MMS /Macro = (UCX=1) for VAXC - UCX + $ MMS /Macro = (CMU_TCP=1) for VAXC - OpenCMU TCP/IP + $ MMS /Macro = (SOCKETSHR_TCP=1) for VAXC - SOCKETSHR/NETLIB + $ MMS /Macro = (TCPWARE=1) for VAXC - TCPWare TCP/IP + + $ MMS /Macro = (MULTINET=1, DEC_C=1) for DECC - MultiNet + $ MMS /Macro = (WIN_TCP=1, DEC_C=1) for DECC - Wollongong TCP/IP + $ MMS /Macro = (UCX=1, DEC_C=1) for DECC - UCX + $ MMS /Macro = (CMU_TCP=1, DEC_C=1) for DECC - OpenCMU TCP/IP + $ MMS /Macro = (SOCKETSHR_TCP=1,DEC_C=1) for DECC - SOCKETSHR/NETLIB + $ MMS /Macro = (TCPWARE=1, DEC_C=1) for DECC - TCPWare TCP/IP + + $ MMS /Macro = (MULTINET=1, GNU_C=1) for GNUC - MultiNet + $ MMS /Macro = (WIN_TCP=1, GNU_C=1) for GNUC - Wollongong TCP/IP + $ MMS /Macro = (UCX=1, GNU_C=1) for GNUC - UCX + $ MMS /Macro = (CMU_TCP=1, GNU_C=1) for GNUC - OpenCMU TCP/IP + $ MMS /Macro = (SOCKETSHR_TCP=1,GNU_C=1) for GNUC - SOCKETSHR/NETLIB + $ MMS /Macro = (TCPWARE=1, GNU_C=1) for GNUC - TCPWare TCP/IP + + If you just type "MMS" it will default to the MULTINET and VAXC + configuration. MMS will build the WWW library and Lynx sources, and + link the executable. However, not all of the header dependencies are + specified. If you are not a developer, and need a clean build, you + should use build.com instead of the MMS utility. + + If you want SOCKS support on VMS, you must add SOCKS as a compilation + definition, and the SOCKS library to the link command. However, instead + of SOCKSifying Lynx for use behind a firewall, you are better off if you + build Lynx normally, and set up Lynx to use a proxy server (see below). + You instead can SOCKSify the proxy server, and it will handle all clients, + not just Lynx. + +------------------------------------------------------------------------------- + +IV.

Before compiling the Lynx sources, you + need a curses library, and it is recommended that you have the zlib + library. Get pdcurses2.3 from "http://pdcurses.sourceforge.net/". I + have modified it so that mouse support is no longer broken for Lynx (see + "http://www.fdisk.com/doslynx/"). You will want to get zlib from + "http://www.zlib.net/ ". Compile these libraries, and + put them in a convenient place (pdcurses inside the Lynx directory). + + Unpack the latest Lynx source distribution, and make an obj directory + under the source root to contain the compile output. Copy in your + IDE file. A sample IDE file and helper libraries are available at + "http://www.fdisk.com/doslynx/wlynx/source/". + + First build the .h files in src\chrtrans using "makew32.bat". Double + check for new .tbl files; hand edit in any new ones, and then do "makew32". + Jump into Borland C++, load the project (IDE file) and compile Lynx. + Alternately, after compiling the chartrans tables, you can come back to + the top directory and compile manually, i.e., do "make -f makefile.bcb". + + I also have a binary available at "http://www.fdisk.com/doslynx/". This + binary was compiled with pdcurses 2.3, hacked so win32 mouse support works, + and with zlib, so Lynx can do gzip routines internally. More hints and + information can be found in "http://www.fdisk.com/doslynx/lynxport.htm". + +-- 1997/10/12 - W. Buttles <lynx-port@fdisk.com> +-- 2010/11/27 - URL's updated by Doug Kaufman <dkaufman@rahul.net> + +------------------------------------------------------------------------------- + +Cygwin: + It is possible to compile under the cygwin system, which will allow you to + use the configure script described above for Unix. Type, for example, + "./configure --with-screen=ncurses --with-libz" in a Dos window running the + cygwin bash$ shell. You also have the choice of using either pdcurses or + slang. You will need a launch program such as sh.exe to call helper + applications. Paths may need to be in cygwin style, rather than Windows + style (e.g., TMPDIR=/cygdrive/d/cygwin/tmp, rather than + TMPDIR=d:\cygwin\tmp). + +Visual C++: + You must have compiled zlib and PDCurses with the -MT (threaded code) + option. This is not the default with zlib (see Makefile.msc). + + Copy into lib the following + zconf.h + zlib.h + zlib.lib + + from the zlib build-tree, and + curses.h + pdcurses.lib + + from the PDCurses build-tree. + + Then + make-msc + + to build lynx. + +------------------------------------------------------------------------------- + +V. Compile instructions -- 386 DOS + + Compiling for DOS with DJGPP has traditionally been a multistep + procedure. Now, if you have a full installation of DJGPP you can + also install using the configure script, just as in the UNIX + section. This needs to be done under a BASH shell. Use a shell + script to run configure as in the example at the end of this + section. Otherwise you can follow the below instructions. The + multistep procedure for DOS may not be supported in the future + and use of the configure script is recommended. The information + about required libraries and unpacking applies to both methods of + compiling. + + First install the C compiler and its libraries (see readme.1st from + DJGPP distribution). + + Originally, lynx makefiles come with the initial -O2 optimization + level. If you experience compilation process too slow due to paging + to the disk (DPMI server provide virtual memory, when in lack of + RAM), you may change optimization to -O1 or turn the optimization + off entirely. + + If using optimization level -O2 or -O3 with older versions of DJGPP + and GCC, you may need to "stubedit" your "cc1.exe" file to enlarge + compiler stack size. For instance, if using DJGPP 2.02 and GCC 2.8.1, + to compile with -O3 optimization, the stub needs to be edited to give + a larger stack. To do this go into djgpp\lib\gcc-lib\djgpp\2.81 and + either type the command: + "stubedit cc1.exe bufsize=63k minstack=2M", + or edit interactively with: "stubedit cc1.exe". Current versions of + DJGPP and GCC generally work with the standard stack. + + Unpack the source code using a DOS program like UNZIP386. If you are + using PKUNZIP to unpack the .zip archive, you must use the -d command + line switch to restore the directory structure contained in the archive, + i.e., do "pkunzip -d lynx-cur.zip". No switch is required if you use + unzip386 or unzip. If you are trying to compile the 386DOS port under a + WinNT DOS shell, be sure to unpack the source with a DOS program so + that all directories will be adjusted to the DOS 8.3 file format necessary + for compiling with DJGPP. Do NOT use Winzip, because that will create + long filenames that will not be recognized by DJGPP tools. + + If you wish to compile with "USE_ZLIB" (recommended), you must have the + zlib library. Get the source from + http://www.zlib.net + and compile it. Put libz.a in the lib subdirectory of DJGPP, and put + zlib.h and zconf.h in the include subdirectory. + + In addition to the files in the Lynx distribution, you will need a curses + package and a TCP package. You can use PDCurses (available at + "http://pdcurses.sourceforge.net/") and the DJGPP port of WATTCP. The + updated version of WATTCP is known as WATT-32, and is available at + "http://home.broadpark.no/~gvanem/". You can also use slang (available at + "http://www.jedsoft.org/slang/") as your screen library. You must + compile these before you go any further. If you wish to use PDCurses 2.6, + you need to first apply the following patch: + +--- dos/gccdos.mak.ori 2002-01-11 20:11:18.000000000 -0800 ++++ dos/gccdos.mak 2003-12-13 21:29:28.000000000 -0800 +@@ -40,11 +40,11 @@ + CFLAGS = -c -g -Wall -DPDCDEBUG + LDFLAGS = -g + else +- CFLAGS = -c -O -Wall ++ CFLAGS = -c -O2 -Wall + LDFLAGS = + endif + +-CPPFLAGS = -I$(PDCURSES_HOME) -I$(CCINCDIR) -D_NAIVE_DOS_REGS ++CPPFLAGS = -I$(PDCURSES_HOME) -I$(CCINCDIR) -D_NAIVE_DOS_REGS -DHAVE_STRING_H + + CCFLAGS = $(CFLAGS) $(CPPFLAGS) + +@@ -64,10 +64,10 @@ + all: $(PDCLIBS) $(DEMOS) + + clean: + -del *.o +- -del curses.lib +- -del panel.lib ++ -del pdcurses.a ++ -del panel.a + + demos: $(DEMOS) + +@@ -287,33 +287,27 @@ + #------------------------------------------------------------------------ + + firework.exe: firework.o $(LIBCURSES) +- $(LINK) $(LDFLAGS) -o firework firework.o $(LIBCURSES) +- $(COFF2EXE) firework ++ $(LINK) $(LDFLAGS) -o firework.exe firework.o $(LIBCURSES) + strip $@ + + newdemo.exe: newdemo.o $(LIBCURSES) +- $(LINK) $(LDFLAGS) -o newdemo newdemo.o $(LIBCURSES) +- $(COFF2EXE) newdemo ++ $(LINK) $(LDFLAGS) -o newdemo.exe newdemo.o $(LIBCURSES) + strip $@ + + ptest.exe: ptest.o $(LIBCURSES) $(LIBPANEL) +- $(LINK) $(LDFLAGS) -o ptest ptest.o $(LIBCURSES) $(LIBPANEL) +- $(COFF2EXE) ptest ++ $(LINK) $(LDFLAGS) -o ptest.exe ptest.o $(LIBCURSES) $(LIBPANEL) + strip $@ + + testcurs.exe: testcurs.o $(LIBCURSES) +- $(LINK) $(LDFLAGS) -o testcurs testcurs.o $(LIBCURSES) +- $(COFF2EXE) testcurs ++ $(LINK) $(LDFLAGS) -o testcurs.exe testcurs.o $(LIBCURSES) + strip $@ + + tuidemo.exe: tuidemo.o tui.o $(LIBCURSES) +- $(LINK) $(LDFLAGS) -o tuidemo tuidemo.o tui.o $(LIBCURSES) +- $(COFF2EXE) tuidemo ++ $(LINK) $(LDFLAGS) -o tuidemo.exe tuidemo.o tui.o $(LIBCURSES) + strip $@ + + xmas.exe: xmas.o $(LIBCURSES) +- $(LINK) $(LDFLAGS) -o xmas xmas.o $(LIBCURSES) +- $(COFF2EXE) xmas ++ $(LINK) $(LDFLAGS) -o xmas.exe xmas.o $(LIBCURSES) + strip $@ + + +--- dos/pdckbd.c.ori 2002-09-01 00:13:30.000000000 -0800 ++++ dos/pdckbd.c 2004-01-19 20:30:02.000000000 -0800 +@@ -362,7 +362,7 @@ + return ((int) (0xb8 << 8)); + if (ascii == 0xe0 && scan == 0x53 && pdc_key_modifiers & PDC_KEY_MODIFIER_SHIFT) /* Shift Del */ + return ((int) (0xb9 << 8)); +- if (ascii == 0x00 || ascii == 0xe0) ++ if (ascii == 0x00 || (ascii == 0xe0 && scan != 0x00)) + return ((int) (scan << 8)); + return ((int) (ascii)); + } +@@ -522,7 +522,7 @@ + _watch_breaks(); + #else + # ifdef GO32 +- (void*)signal(SIGINT,(setting ?

See the file + "INSTALL.DJGPP" in the OpenSSL distribution. + + If you have trouble applying the patches, try using the "patch" program, + ("http://www.delorie.com/pub/djgpp/current/v2gnu/pat261b.zip"). + To read the Unix man style documentation, use, for example, "less" + ("http://www.delorie.com/pub/djgpp/current/v2gnu/lss374b.zip"). + Compile or place your compiled PDCurses library in /djgpp/pdcur26, and + compile or place your compiled WATT-32 library in /djgpp/watt32. If + using the SLANG library, put libslang.a in your DJGPP/lib directory and put + slang.h in your DJGPP/include directory, or in the appropriate directories + specified by LIBRARY_PATH and INCLUDE_PATH in your DJGPP.ENV file. + + Move to the "lynx2-*/WWW/Library/djgpp" directory. If compiling with + PDCurses, do "make". If using SLANG, do "make -f makefile.sla". This + should compile libwww.a. Next move to the "lynx2-*/src/chrtrans" directory + and do "make -f makefile.dos" to compile the character tables. Then move + to the "lynx2-*/src" directory. There are three choices for compiling at + this point. You can do "make -f makefile.dos" to compile with PDCurses, + "make -f makefile.wsl" to compile with SLANG, or "make -f makefile.dsl" to + compile with SLANG and the DJGPP keyhandler. At the time of this writing, + it is not clear what the advantages and disadvantages of each version are. + The PDCurses version has the most experience and allows remapping of ALT + and Function keys. The SLANG version seems to have better screen handling. + It allows mapping of function keys, but not ALT keys. The SLANG with DJGPP + keyhandler allows mapping of ALT and Function keys, but has the risk of + incompatibilities from mixing different programs. + + If you wish to compile with support for internationalization of messages, + you first need to install the DOS ports of the GNU gettext and libiconv + packages, available from any DJGPP mirror site. Then uncomment the lines + for INTLFLAGS in src/makefile.dsl and in WWW/Library/djgpp/makefile.sla, + and remove the "#" from the LIBS line in src/makefile.dsl. Make similar + changes if using one of the other DOS makefiles. See the gettext + documentation for information on creating and using message files for + different languages. + + If all goes well, you will have a lynx.exe file. If you have trouble, + check to be sure djgpp.env is the way it came in the original package. + + To test Lynx_386 you must have a packet driver installed. The simplest + method is to use a null packet driver that just allows Lynx to start + up, but doesn't do anything else. One such executable driver has been + posted, uuencoded, to the lynx-dev mailing list in January 1998, + but is corrupted in the mailing list archive. You can get this at + "http://www.ncf.ca/ncf/pda/computer/dos/net/nullpkt.zip". Start the + dummy packet driver with "nullpkt 0x60", and take it out of memory with + "nullpkt -u". You can also use slip8250.com. See the CRYNWR package + "ftp://ftp.simtel.net/pub/simtelnet/msdos/pktdrvr/pktd11.zip". Usage + is "slip8250 0x60", but you may have to invoke it as, for example, + "slip8250 0x60 6 3 0x2F8" so that it uses COM2 and IRQ 3, in order to + avoid an IRQ conflict with a mouse or some other device. Another packet + driver is slipper.exe, which is available from many sites, including + "http://www.cavazza.it/file/bbs/intsoft/slippr15.zip". To remove it from + memory use termin.com (usage "termin 0x60"), available in the CRYNWR + package. To connect over a dialup PPP connection you need dosppp or klos' + pppshare. (Find at: + "http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/net/dosppp/dosppp06.zip" + "http://www.ncf.carleton.ca/ncf/pda/computer/dos/net/dosppp06.zip" + "http://www.cavazza.it/file/bbs/intsoft/dosppp06.zip" + "http://www.cavazza.it/file/bbs/intsoft/pppshare.exe") + + File access looks like this: + + file:///c:/ + file:///c:/dos + file:///c:/dos/command.com + file://localhost/c:/ + file://localhost/c:/dos + file://localhost/c:/dos/command.com + + See "http://www.fdisk.com/doslynx/lynxport.htm" for more hints and + some precompiled libraries. One problem you can encounter is editing + userdefs.h and lynx.cfg, which have unix-style end of lines. You would + be well advised to use an editor that can handle end of lines terminated + with a single LF character. You can also unpack the source code using + unzip386 or unzip with the -a or -aa switch to convert unix LF to dos CRLF. + That will make texts more readable under DOS. If you compile lynx + regularly, you may automate the procedure by creating a batch file such + as the following. + + cd djgpp\watt32\src + configur djgpp + make -f djgpp.mak + cd ..\..\..\www\library\djgpp + make + cd ..\..\..\src\chrtrans + make -f makefile.dos + cd ..\..\src + make -f makefile.dos + strip lynx.exe + cd .. + + This batch file expects the DJGPP port of WATT-32 to be installed in the + lynx2-* directory. Place a copy of this batch file, named "djgpp.bat", + in the lynx2-* directory, move to that directory and type "djgpp". A more + complete batch file with error checking and annotation can be found at: + "http://lists.nongnu.org/archive/html/lynx-dev/1997-11/msg00250.html". + + If you use the configure method, remember that if you configure with + the option "--enable-nls", you also need to set LIBS="-liconv". A + sample shell script to run configure using PDCurses follows. If you + compile to use SLANG, note that the DJGPP keyhandler will be used + instead of the SLANG keyhandler unless you define "NO_DJ_KEYHANDLER". + + #!/bin/sh + CFLAGS="-O2 -I/djgpp/pdcur26 -I/djgpp/watt32/inc" \ + LIBS="-L/djgpp/pdcur26/lib -L/djgpp/watt32/lib -liconv" \ + ./configure --prefix=d:/djgpp/lynx-rel/lynx-cnf \ + --with-screen=curses \ + --disable-full-paths \ + --enable-addrlist-page \ + --enable-change-exec \ + --enable-cgi-links \ + --enable-charset-choice \ + --enable-color-style \ + --enable-exec-links \ + --enable-externs \ + --enable-file-upload \ + --enable-nested-tables \ + --enable-nls \ + --sysconfdir=d:/djgpp/lynx-rel/lynx-cnf \ + --with-bzlib \ + --with-zlib \ + --with-ssl + +-- 1997/9/29 - D. Kaufman <dkaufman@rahul.net> +-- 1997/10/3 - B. Schiavo <Wschiavo@concentric.net> +-- Last update - 2010/11/27 + +------------------------------------------------------------------------------- + +VI. General installation instructions + + Once you have compiled Lynx, test it out first on a local file. Be sure + Lynx can find lynx.cfg. A _sample_ test command line would be: + 'lynx -cfg=/usr/local/lib/lynx.cfg .'. Once you are satisfied that + Lynx works, go ahead and install it. For Unix, type "make install". + + For VMS, you need to have the executable in a public place, make it + accessible, define it as a foreign command, and copy lynx.cfg to + "Lynx_Dir". Look at lynx.com in the samples directory as a model for + installing Lynx. To include lynx.hlp in the system HELP library, use + the command: "$ library/replace sys$help:helplib.hlb lynx.hlp". + + Local copies of the Lynx online help should be made accessible in response + to the Lynx 'h'elp command by defining HELPFILE in userdefs.h and/or + lynx.cfg to an appropriate file://localhost/path URL. On Unix, all you + need to do is type "make install-help." If you are installing manually, + copy the files "COPYHEADER" and "COPYING" into the lynx_help directory + BEFORE moving the lynx_help tree to its final location. These files are + referenced hypertextually from help documents. + + If you have old, pre-existing bookmark files from earlier versions of + Lynx, those files may have to be updated. Conversion may just consist + of adding one META line near the top, or may require creating new book- + mark files and editing in bookmarks from outdated files. + + IMPORTANT! Be sure you have read the warnings about setting up an + anonymous account with Lynx if you plan to give public access to Lynx. + + After applying patches or editing files to correct for an unsuccessful + build, be certain to do a "make clean" (or "make distclean" for those + using auto-configure) before attempting to compile again. + +------------------------------------------------------------------------------- + +VII. Setting environment variables before running Lynx (optional) + +1. All ports + + The Lynx Users Guide describes all of the environment variables used by + Lynx. This should be checked later along with reading lynx.cfg after you + have installed Lynx. + +2. Win32 (95/98/NT) and 386 DOS + + These ports cannot start before setting certain environment variables. + Here are some environment variables that should be set, usually in a + batch file that runs the lynx executable. Make sure that you have enough + room left in your environment. You may need to change your "SHELL=" + setting in config.sys. In addition, lynx looks for a "SHELL" environment + variable when shelling to DOS. If you wish to preserve the environment + space when shelling, put a line like this in your AUTOEXEC.BAT file also + "SET SHELL=C:\COMMAND.COM /E:4096". It should match CONFIG.SYS. + + HOME Where to keep the bookmark file and personal config files. + TEMP or TMP Bookmarks are kept here with no HOME. Temp files here. + USER Set to your login name (optional) + LYNX_CFG Set to the full path and filename for lynx.cfg + LYNX_LSS Set to the full path and filename for lynx.lss + LYNX_SAVE_SPACE The (modifiable) location for downloaded file storage. + SSL_CERT_FILE Set to the full path and filename for your file of trusted + certificates + + 386 version only: + WATTCP.CFG Set to the full path for the WATTCP.CFG directory + RL_CLCOPY_CMD Command to copy a URL to a "clipboard" file + RL_PASTE_CMD Command to go to a URL in your "clipboard" file + + Define these in your batch file for running Lynx. For example, if your + application line is "D:\win32\lynx.bat", lynx.bat for Win32 may look like: + @ECHO OFF + set home=d:\win32 + set temp=d:\tmp + set lynx_cfg=d:\win32\lynx.cfg + set lynx_save_space=d:\download + d:\win32\lynx.exe %1 %2 %3 %4 %5 + + For lynx_386, a typical batch file might look like: + + @echo off + set HOME=f:/lynx2-8 + set USER=your_login_name + set LYNX_CFG=%HOME%/lynx.cfg + set WATTCP.CFG=%HOME% + f:\lynx2-8\lynx %1 %2 %3 %4 %5 %6 %7 %8 %9 + + You need to make sure that the WATTCP.CFG file has the correct information + for IP number, Gateway, Netmask, and Domain Name Server. This can also be + automated in the batch file. + + Adapted from "readme.txt" by Wayne Buttles and "readme.dos" by Doug + Kaufman. + +VIII.
