Use quotes if variables contain 17 # whitespace or shell meta characters. 18 # .IP \fBAUXLIBS=\fIobject_library...\fR 19 # Specifies one or more non-default object libraries. 20 # .IP \fBCC=\fIcompiler_command\fR 21 # Specifies a non-default compiler. On many systems, the default 22 # is \fBgcc\fR. 23 # .IP \fBCCARGS=\fIcompiler_arguments\fR 24 # Specifies non-default compiler arguments, for example, a non-default 25 # \fIinclude\fR directory. 26 # The following directives are special: 27 # .RS 28 # .IP \fB-DNO_DB\fR 29 # Do not build with Berkeley DB support. 30 # .IP \fB-DNO_DEVPOLL\fR 31 # Do not build with Solaris /dev/poll support. 32 # By default, /dev/poll support is compiled in on platforms that 33 # are known to support it. 34 # .IP \fB-DNO_EPOLL\fR 35 # Do not build with Linux EPOLL support. 36 # By default, EPOLL support is compiled in on platforms that 37 # are known to support it. 38 # .IP \fB-DNO_IPV6\fR 39 # Do not build with IPv6 support. 40 # By default, IPv6 support is compiled in on platforms that 41 # are known to have IPv6 support. 42 # 43 # Note: this directive is for debugging and testing only. It 44 # is not guaranteed to work on all platforms. 45 # .IP \fB-DNO_KQUEUE\fR 46 # Do not build with FreeBSD/NetBSD/OpenBSD/MacOSX KQUEUE support. 47 # By default, KQUEUE support is compiled in on platforms that 48 # are known to support it. 49 # .IP \fB-DNO_NIS\fR 50 # Do not build with NIS or NISPLUS support. Support for NIS 51 # is unavailable on some recent Linux distributions. 52 # .IP \fB-DNO_NISPLUS\fR 53 # Do not build with NISPLUS support. Support for NISPLUS 54 # is unavailable on some recent Solaris distributions. 55 # .IP \fB-DNO_PCRE\fR 56 # Do not build with PCRE support. 57 # By default, PCRE support is compiled in when the \fBpcre-config\fR 58 # utility is installed. 59 # .IP \fB-DNO_POSIX_GETPW_R\fR 60 # Disable support for POSIX getpwnam_r/getpwuid_r. 61 # .IP \fB-DNO_SIGSETJMP\fR 62 # Use setjmp()/longjmp() instead of sigsetjmp()/siglongjmp(). 63 # By default, Postfix uses sigsetjmp()/siglongjmp() when they 64 # appear to work. 65 # .RE 66 # .IP \fBDEBUG=\fIdebug_level\fR 67 # Specifies a non-default debugging level. The default is \fB-g\fR. 68 # Specify \fBDEBUG=\fR to turn off debugging. 69 # .IP \fBOPT=\fIoptimization_level\fR 70 # Specifies a non-default optimization level. The default is \fB-O\fR. 71 # Specify \fBOPT=\fR to turn off optimization. 72 # .IP \fBWARN=\fIwarning_flags\fR 73 # Specifies non-default gcc compiler warning options for use when 74 # "make" is invoked in a source subdirectory only. 75 # LICENSE 76 # .ad 77 # .fi 78 # The Secure Mailer license must be distributed with this software. 79 # AUTHOR(S) 80 # Wietse Venema 81 # IBM T.J.
