Installing the pre-compiled binary package + ------------------------------------------ + + 1. Unzip the file groNNNb.zip (where NNN is the version number) + preserving the directory structure (-d switch to PKUNZIP) from + the main DJGPP installation directory. If you will use Groff + on Windows 9x, Windows 2000, or later, use an unzip program + which supports long filenames. + + 2. Groff binaries were configured so that they will look for their + standard directories under the directory pointed to by the + DJDIR environment variable, so it should work automatically if + you have DJGPP installed. If you don't have a standard DJGPP + installation, set the variable DJDIR to point to the directory + where you unzip Groff. In this latter case, you will need to + set additional environment variables: + + GROFF_TMAC_PATH=%DJDIR%/share/groff/<version>/tmac:%DJDIR%/share/groff/site-tmac + GROFF_TYPESETTER=ascii + GROFF_FONT_PATH=%DJDIR%/share/groff/<version>/font + + <version> is something like '1.16.1' or '1.17'. + + In addition, you can set the variable GROFF_TMPDIR to point to + a directory where you want Groff to create temporary files it + needs for running its jobs (these files are automatically + deleted when Groff exits). + + All of those variables are automatically set in the file + DJGPP.ENV that is part of the standard DJGPP distribution + djdevNNN.zip (where NNN is the DJGPP version number), so you + only need to set them manually if you don't have DJGPP + installed. + + Note that the GROFF_TYPESETTER variable sets the default Groff + device to be 'ascii', which is suitable for formatting man + pages to be viewed on the terminal. Use the -T switch to + generate output for other devices (e.g., -Tps for PostScript). + + 3. If your TMPDIR environment variable points to a RAM drive, you + might consider changing GROFF_TMPDIR to point to a directory on + a real disk drive, especially if you intend to generate + PostScript output, because RAM disks are typically small (2-3 + MBytes) which might be not enough for formatting large + documents. + + 4. Read the docs. It comes as formatted manual pages called *.1, + *.5 and *.7 which unzip into your man/ subdirectory. You + can read them with a pager such as GNU Less (recommended, as + Less will use colors for bold and underlined text) or with + Info (which will remove the bold/underline attributes). + Another alternative is to use Emacs built-in man page reader; + the DJGPP FAQ lists other possibilities. + + Beginning with version 1.15, Groff comes with an Info manual; + type "info -f groff" to read it. The Info manual is still + under construction, so some sections are empty. + + If you want to add a Groff entry to the main Info menu in the + file DIR, chdir to the 'info' subdirectory of the main Groff + installation directory and run this command: + + install-info --dir-file=dir groff.info + + After you do that, "info groff" will also work. + + 5. For those who only need Groff to format man pages and don't + like reading the docs, here's a minimal cookbook: + + groff -man -s foo.1 > foo.man + + where 'foo.1' is the troff source of the man page and 'foo.man' + is the formatted page. If you need to view the man page, say + this: + + groff -man -s foo.1 | less + + You can also use the DJGPP clone of the Unix 'man' command, in + which case 'man' runs the above command for you automatically. + + Here's how you print man pages on a PostScript printer: + + groff -man -s -Tps foo.1 > prn + + And this is for a LaserJet4 printer: + + groff -man -s -Tlj4 foo.1 > prn + + Printing the documents produced by Groff is possible either by + redirecting Groff's standard output to the local printer + device, like shown above, or by using the '-l' switch to Groff. + The latter possibility causes Groff to pipe its output to a + program whose name and arguments appear in the files named + 'DESC' in each of the 'devFOO' subdirectories of the + %DJDIR%/share/groff/<version>/font directory; for example, the + file devps/DESC is used by "groff -Tps". The relevant line in + these files begins with the word "print". + + As configured, when invoked with the '-l' switch, Groff will + call 'cat' (from GNU Textutils) to pipe its output to the + default printer device for -Tps, -Tlbp and -Tlj4 options, and + it will call 'dvilj4' (from the dvljNNNb.zip package) for -Tdvi + option. If you don't have these programs installed, you can + edit the respective 'DESC' files to replace these commands with + something else. The replacement program must be able to read + its standard input and send its output to whatever printer you + want. The "print" entry is assumed to be a shell command, so + it can use redirection, pipes, and other shell features. + + Beginning with version 1.15, Groff can create HTML output, like + this: + + groff -man -s -Thtml foo.1 > foo.html + + Producing HTML files sometimes requires Ghostscript to be + installed, and, for gif images, ppmquant and ppmtogif as well. + If you do not have these programs installed, Groff will print + an error message, and the produced file will have links which + will fail to resolve when you view it with a Web browser. + + 6. Some programs in the package are supplied as Unix shell + scripts. While it is relatively easy to write a DOS batch file + which will do the same, DOS doesn't allow to redirect input and + output of a batch file. Since Groff tools are meant to be + invoked in a pipe, the batch files are not very useful. The + batch files are included in the binary distribution + nonetheless. + + These scripts need the following utilities to run (in addition + to the Groff programs they invoke): + + - bash + - gawk + - egrep + - sed + + The 'afmtodit' and 'mmroff' utilities are Perl scripts, so you + will need a Perl port to run them. + + All of these ports should be available from the DJGPP sites. + + If you need to run these scripts and batch files, you have to + install the port of bash (or another Unix-like shell) and the + above-mentioned utilities called by the script. Alternatively, + just look inside the shell script and invoke the programs it + calls manually. + + To run the scripts with redirection, invoke them via the shell, + like this: "sh mmroff > foo". + + 7. Note that Groff programs use floating point, so you will need + an FP emulator if your machine doesn't have an FPU. The binary + distribution includes the emulator, in case you don't have the + DJGPP development environment installed. Please refer to the + DJGPP FAQ list in case you have any problems with the emulator. + + 8. The package does not include the directories under + share/groff/<version>/font whose names begin with "devX": these + are needed on the X Window System for running the gxditview + program, which is not supported by this port. + + 9. Due to 8+3 limitations of DOS filesystems, several files were + renamed: + + - groff_mdoc.samples.7 was renamed to groff-mdoc_samples.7 + and groff_mmse.7 to groff-mmse.7. The latter was also + converted from Latin-1 encoding to codepage 437. + + + +II. Building Groff from sources + --------------------------- + + 1. To build Groff, you will need the following tools (the file + name in parentheses is what you need to download from one of + the DJGPP sites): + + - Standard DJGPP development environment (djdev203.zip) + - GNU C compiler (gcc2721b.zip) + - GNU C++ compiler (gpp2721b.zip) + - GNU Make 3.79 (mak379b.zip) + - Bash v2.03 (bsh203b.zip) + - Fileutils 3.16 (fil316b.zip) + - Textutils 2.0 (txt20b.zip) + - Sh-utils 1.12 (shl112b.zip) + - Sed 3.02 (sed302b.zip) + - Gawk 3.04 (gwk304b.zip) + - Grep 2.4 (grep24b.zip) + - Bison (only if you change one of the *.y files) + + Note that you don't need to install libg++ (lgpNNNb.zip) since + Groff doesn't use any C++ classes except its own. + + Any versions of the utilities later than what's mentioned above + should also do; in particular, GCC 2.95.2 was tested and Groff + built okay with it. Versions older than in the above list + might also work, but I don't guarantee that; you are on your + own. + + Special considerations apply if you have GCC 2.8.1 installed, + and cannot upgrade to a later version. See paragraph 4 below. + + After you install these tools, make sure you have a "symlink" + to bash.exe called sh.exe and a "symlink" to gawk.exe called + awk.exe. If not, go to the DJGPP bin/ subdirectory and type + the following words of wisdom from the DOS prompt: + + ln -s bash.exe sh.exe + ln -s gawk.exe awk.exe + + ('ln' is part of GNU Fileutils, see above.) + + 2. Unzip the source distribution groXYZs.zip (where XYZ is the + version number) preserving the directory structure (-d switch + to PKUNZIP) from the main DJGPP installation directory. (If + you are building Groff on Windows 9x, Windows 2000, or later, + use an unzip program which supports long filenames.) This + creates directory gnu/groff-X.YZ and unzips the sources there. + + If you are building from the official GNU distribution, unpack + the .tar.gz archive like this: + + djtar -x groff-X.YZ.tar.gz + + (DJTAR is part of the standard DJGPP development distribution.) + + 3. Groff sources on DJGPP sites are already configured for the + current version of DJGPP. If that is the version you have, + then you can just chdir to gnu/groff-X.YZ and say "make" to + build the entire package (if you have GCC 2.8.1, see the next + paragraph). + + If you have version of DJGPP other than the current one, or if + you build the official GNU distribution, or if you prefer to + configure the package so that it defaults to the directory + structure on your machine, or need to change some options + (e.g., compile with different optimization options), you will + have to reconfigure Groff. To this end, use the CONFIG.BAT + batch file in the DJGPP subdirectory: + + arch\djgpp\config + + You can configure and build Groff from outside its source + directory. In that case, you need to pass the full path to the + source directory as an argument to CONFIG.BAT, like this: + + d:\gnu\groff-1.16\arch\djgpp\config d:/gnu/groff-1.16 + + Note that you MUST use forward slashes in the path you pass to + CONFIG.BAT, or else it may fail. (For versions of Groff other + than 1.16, change the above command accordingly.) + + 4. If your version of GCC is 2.8.1, you cannot build the + preconfigured package without some tinkering. The DJGPP port + of GCC 2.8.1 had a bug in its C++ configuration, whereby the + file _G_config.h erroneously indicated that the header + <sys/socket.h> is available, and also undefined the symbol + NULL. This causes several files in the Groff distribution to + fail to compile. + + The easiest way to solve this is to upgrade to a later version + of GCC; then you can simply say "make" to build the + preconfigured package. If this is not an option, you will have + to edit the file lang/cxx/_G_config.h and change this line: + + #define _G_HAVE_SYS_SOCKET 1 + + to say this instead: + + #define _G_HAVE_SYS_SOCKET 0 + + The problem with redefining NULL should not happen with DJGPP + v2.03 or later. But if you still see compilation errors which + say "'NULL' undeclared", comment out the line in _G_config.h + that says this: + + #undef NULL + + Alternatively, you can reconfigure the package as described in + the previous paragraph, before building it. + + 5. After the configure script exits, say "make" to build Groff. + Groff is a large package, and it might take a few minutes to + build, depending on your CPU, so you might as well go for a + coffee while it grinds away. + + 6. Test the package that you have built. A batch file T-GROFF.BAT + in the DJGPP subdirectory is supplied for that purpose. Most + of the commands there are commented out, since I cannot + possibly know what kind of printer do you have and which + additional programs, such as Less, do you have installed. The + only command that runs by default will format a large document + and print it to the screen. Read the comments in the batch + file, uncomment additional lines as you see fit and run the + batch file to see that you get the document printed as you'd + expect. (Btw, the document that the batch file prints is an + introduction to the entire Groff package, so you might as well + read it to make yourself familiar with the programs.) + + Note that the batch file sets a lot of environment variables; + if you get "Out of environment space" messages, launch a + subsidiary COMMAND.COM with plenty of environment space, like + so: + + command.com /e:3000 + + then invoke T-GROFF.BAT from that COMMAND.COM. + + 7. Install the package by typing "make install". This will copy + all the binaries, the auxiliary files (fonts, macros, etc.) and + the docs into their places. If you configured the package for + your system, these are precisely the directories where the + files should remain (with the exception of the man pages, see + below). If you use the default configuration, the files will + be installed under the top DJGPP installation directory. + + Alternatively, you could instruct Make explicitly where to + install the package by setting the 'prefix' variable. For + example: + + make install prefix=c:/groff + + "make install" doesn't format the man pages, it just copies + them into subdirectories of the %DJDIR%\MAN directory. If you + need to keep formatted pages in your man/ subdirectory, you + will need to format them. Use the commands shown in chapter I, + section 5 above to do that, and redirect its output to the + appropriate catN subdirectory. Alternatively, you could format + the pages when you need to view them (the DJGPP clone of 'man' + will automatically format them). + + Consult the installation instructions for pre-compiled binaries + above, for more info about installing and using Groff. + + 8. You can safely delete the directories under + share/groff/<version>/font whose names begin with "devX": these + are used by the X Window System client 'gxditview', which is + not supported by this port. + + +##### Editor settings +Local Variables: +mode: text +fill-column: 70 +End: +vim: set autoindent textwidth=70: |
