Use quotes if variables contain whitespace # or shell meta characters. # # The command "\fBmake makefiles name=value...\fR" will replace # the string \fBMAIL_VERSION\fR at the end of a value with the # Postfix version (\fImajor.minor.patchlevel\fR for a stable # release, \fImajor.minor-date\fR for a development release). # Do not try to specify something like \fB$mail_version\fR: # that produces inconsistent results with different implementations # of the make(1) command. # .IP \fBAUXLIBS=\fIobject_library...\fR # Specifies one or more non-default object libraries. Postfix # 3.0 and later specify some of their database library # dependencies with AUXLIBS_CDB, AUXLIBS_LDAP, AUXLIBS_LMDB, # AUXLIBS_MYSQL, AUXLIBS_PCRE, AUXLIBS_PGSQL, AUXLIBS_SDBM, # and AUXLIBS_SQLITE, respectively. # .IP \fBCC=\fIcompiler_command\fR # Specifies a non-default compiler. On many systems, the default # is \fBgcc\fR. # .IP \fBCCARGS=\fIcompiler_arguments\fR # Specifies non-default compiler arguments, for example, a non-default # \fIinclude\fR directory. # The following directives are special: # .RS # .IP \fB-DNO_DB\fR # Do not build with Berkeley DB support. # .IP \fB-DNO_DEVPOLL\fR # Do not build with Solaris /dev/poll support. # By default, /dev/poll support is compiled in on platforms that # are known to support it. # .IP \fB-DNO_DNSSEC\fR # Do not build with DNSSEC support, even if the resolver # library appears to support it. # .IP \fB-DNO_EPOLL\fR # Do not build with Linux EPOLL support. # By default, EPOLL support is compiled in on platforms that # are known to support it. # .IP \fB-DNO_EAI\fR # Do not build with EAI (SMTPUTF8) support. By default, EAI # support is compiled in when the "pkg-config" command is # found, or the deprecated "icu-config" command. # .IP \fB-DNO_INLINE\fR # Do not require support for C99 "inline" functions. Instead, # implement argument typechecks for non-(printf/scanf)-like # functions with ternary operators and unreachable code. # .IP \fB-DNO_IPV6\fR # Do not build with IPv6 support. # By default, IPv6 support is compiled in on platforms that # are known to have IPv6 support. # # Note: this directive is for debugging and testing only. It # is not guaranteed to work on all platforms. If you don't # want IPv6 support, set "inet_protocols = ipv4" in main.cf. # .IP \fB-DNO_IP_CYRUS_SASL_AUTH\fR # Don't pass remote SMTP client and Postfix SMTP server IP # address and port information to the Cyrus SASL library. # This is compatible with Postfix < 3.2. # .IP \fB-DNO_KQUEUE\fR # Do not build with FreeBSD/NetBSD/OpenBSD/MacOSX KQUEUE support. # By default, KQUEUE support is compiled in on platforms that # are known to support it. # .IP \fB-DNO_NIS\fR # Do not build with NIS or NISPLUS support. Support for NIS # is unavailable on some recent Linux distributions. # .IP \fB-DNO_NISPLUS\fR # Do not build with NISPLUS support. Support for NISPLUS # is unavailable on some recent Solaris distributions. # .IP \fB-DNO_PCRE\fR # Do not build with PCRE support. # By default, PCRE support is compiled in when the \fBpcre2-config\fR # or \fBpcre-config\fR utility are installed. # .IP \fB-DNO_POSIX_GETPW_R\fR # Disable support for POSIX getpwnam_r/getpwuid_r. # .IP \fB-DNO_RES_NCALLS\fR # Do not build with the threadsafe resolver(5) API (res_ninit() etc.). # .IP \fB-DNO_SIGSETJMP\fR # Use setjmp()/longjmp() instead of sigsetjmp()/siglongjmp(). # By default, Postfix uses sigsetjmp()/siglongjmp() when they # appear to work. # .IP \fB-DNO_SNPRINTF\fR # Use sprintf() instead of snprintf(). By default, Postfix # uses snprintf() except on ancient systems. # .RE # .IP \fBDEBUG=\fIdebug_level\fR # Specifies a non-default debugging level. The default is \fB-g\fR. # Specify \fBDEBUG=\fR to turn off debugging. # .IP \fBOPT=\fIoptimization_level\fR # Specifies a non-default optimization level. The default is \fB-O\fR. # Specify \fBOPT=\fR to turn off optimization. # .IP \fBPOSTFIX_INSTALL_OPTS=\fI-option...\fR # Specifies options for the postfix-install command, separated # by whitespace. Currently, the only supported option is # \fB-keep-build-mtime\fR. # .IP \fBSHLIB_CFLAGS=\fIflags\fR # Override the compiler flags (typically, "-fPIC") for Postfix # dynamically-linked libraries and database plugins. # # This feature was introduced with Postfix 3.0. # .IP \fBSHLIB_RPATH=\fIrpath\fR # Override the runpath (typically, "'-Wl,-rpath,${SHLIB_DIR}'") # for Postfix dynamically-linked libraries. # # This feature was introduced with Postfix 3.0. # .IP \fBSHLIB_SUFFIX=\fIsuffix\fR # Override the filename suffix (typically, ".so") for Postfix # dynamically-linked libraries and database plugins. # # This feature was introduced with Postfix 3.0. # .IP \fBshared=yes\fR # .IP \fBshared=no\fR # Enable (disable) Postfix builds with dynamically-linked # libraries typically named $shlib_directory/libpostfix-*.so.*. # # This feature was introduced with Postfix 3.0. # .IP \fBdynamicmaps=yes\fR # .IP \fBdynamicmaps=no\fR # Enable (disable) Postfix builds with the configuration file # $meta_directory/dynamicmaps.cf and dynamically-loadable # database plugins typically named postfix-*.so.*. The setting # "dynamicmaps=yes" implicitly enables Postfix dynamically-linked # libraries. # # This feature was introduced with Postfix 3.0. # .IP \fBpie=yes\fR # .IP \fBpie=no\fR # Enable (disable) Postfix builds with position-independent # executables, on platforms where this is supported. # # This feature was introduced with Postfix 3.0. # .IP \fIinstallation_parameter\fB=\fIvalue\fR... # Override the compiled-in default value of the specified # installation parameter(s). The following parameters are # supported in this context: # # command_directory config_directory daemon_directory # data_directory default_database_type html_directory # mail_spool_directory mailq_path manpage_directory meta_directory # newaliases_path queue_directory readme_directory sendmail_path # shlib_directory openssl_path # # See the postconf(5) manpage for a description of these # parameters. # # This feature was introduced with Postfix 3.0. # .IP \fBWARN=\fIwarning_flags\fR # Specifies non-default gcc compiler warning options for use when # "make" is invoked in a source subdirectory only. # LICENSE # .ad # .fi # The Secure Mailer license must be distributed with this software. # AUTHOR(S) # Wietse Venema # IBM T.J.
