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.
