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_DEVPOLL\fR 29 # Do not build with Solaris /dev/poll support. 30 # By default, /dev/poll support is compiled in on platforms that 31 # are known to support it. 32 # .IP \fB-DNO_EPOLL\fR 33 # Do not build with Linux EPOLL support. 34 # By default, EPOLL support is compiled in on platforms that 35 # are known to support it. 36 # .IP \fB-DNO_IPV6\fR 37 # Do not build with IPv6 support. 38 # By default, IPv6 support is compiled in on platforms that 39 # are known to have IPv6 support. 40 # 41 # Note: this directive is for debugging and testing only. It 42 # is not guaranteed to work on all platforms. 43 # .IP \fB-DNO_KQUEUE\fR 44 # Do not build with FreeBSD/NetBSD/OpenBSD/MacOSX KQUEUE support. 45 # By default, KQUEUE support is compiled in on platforms that 46 # are known to support it. 47 # .IP \fB-DNO_PCRE\fR 48 # Do not build with PCRE support. 49 # By default, PCRE support is compiled in when the \fBpcre-config\fR 50 # utility is installed. 51 # .IP \fB-DNO_SIGSETJMP\fR 52 # Use setjmp()/longjmp() instead of sigsetjmp()/siglongjmp(). 53 # By default, Postfix uses sigsetjmp()/siglongjmp() when they 54 # appear to work. 55 # .RE 56 # .IP \fBDEBUG=\fIdebug_level\fR 57 # Specifies a non-default debugging level. The default is \fB-g\fR. 58 # Specify \fBDEBUG=\fR to turn off debugging. 59 # .IP \fBOPT=\fIoptimization_level\fR 60 # Specifies a non-default optimization level. The default is \fB-O\fR. 61 # Specify \fBOPT=\fR to turn off optimization. 62 # .IP \fBWARN=\fIwarning_flags\fR 63 # Specifies non-default gcc compiler warning options for use when 64 # "make" is invoked in a source subdirectory only. 65 # LICENSE 66 # .ad 67 # .fi 68 # The Secure Mailer license must be distributed with this software. 69 # AUTHOR(S) 70 # Wietse Venema 71 # IBM T.J.
