      4 # NAME
      5 #	makedefs 1
      6 # SUMMARY
      7 #	makefile configuration utility
      8 # SYNOPSIS
      9 #	\fBmake makefiles \fIname=value...\fR
     10 # DESCRIPTION
     11 #	The \fBmakedefs\fR command identifies the compilation
     12 #	environment, and emits macro definitions on the standard output
     13 #	stream that can be prepended to template Makefiles.
     14 #
     15 #	Default settings can be overruled by specifying them as
     16 #	environment variables. 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.
