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 and Solaris distributions. 52 # .IP \fB-DNO_PCRE\fR 53 # Do not build with PCRE support. 54 # By default, PCRE support is compiled in when the \fBpcre-config\fR 55 # utility is installed. 56 # .IP \fB-DNO_POSIX_GETPW_R\fR 57 # Disable support for POSIX getpwnam_r/getpwuid_r. 58 # .IP \fB-DNO_SIGSETJMP\fR 59 # Use setjmp()/longjmp() instead of sigsetjmp()/siglongjmp(). 60 # By default, Postfix uses sigsetjmp()/siglongjmp() when they 61 # appear to work. 62 # .RE 63 # .IP \fBDEBUG=\fIdebug_level\fR 64 # Specifies a non-default debugging level. The default is \fB-g\fR. 65 # Specify \fBDEBUG=\fR to turn off debugging. 66 # .IP \fBOPT=\fIoptimization_level\fR 67 # Specifies a non-default optimization level. The default is \fB-O\fR. 68 # Specify \fBOPT=\fR to turn off optimization. 69 # .IP \fBWARN=\fIwarning_flags\fR 70 # Specifies non-default gcc compiler warning options for use when 71 # "make" is invoked in a source subdirectory only. 72 # LICENSE 73 # .ad 74 # .fi 75 # The Secure Mailer license must be distributed with this software. 76 # AUTHOR(S) 77 # Wietse Venema 78 # IBM T.J.
