9# SUMMARY
10#	Postfix makefile configuration utility
11# SYNOPSIS
12#	\fBmake makefiles \fIname=value...\fR
13# DESCRIPTION
14#	The \fBmakedefs\fR command identifies the compilation
15#	environment, and emits macro definitions on the standard
16#	output stream that can be prepended to template Makefiles.
17#	These macros implement an internal interface and are subject
18#	to change without notice.
19# NAME=VALUE OVERRIDES
20# .ad
21# .fi
22#	Default settings can be overruled by specifying them as
23#	environment variables (or as name=value pairs on the "make"
24#	command line). Use quotes if variables contain whitespace
25#	or shell meta characters.
26#
27#	The command "\fBmake makefiles name=value...\fR" will replace
28#	the string \fBMAIL_VERSION\fR at the end of a value with the
29#	Postfix version (\fImajor.minor.patchlevel\fR for a stable
30#	release, \fImajor.minor-date\fR for a development release).
31#	Do not try to specify something like \fB$mail_version\fR:
32#	that produces inconsistent results with different implementations
33#	of the make(1) command.
34# .IP \fBAUXLIBS=\fIobject_library...\fR
35#	Specifies one or more non-default object libraries. Postfix
36#	3.0 and later specify some of their database library
37#	dependencies with AUXLIBS_CDB, AUXLIBS_LDAP, AUXLIBS_LMDB,
38#	AUXLIBS_MYSQL, AUXLIBS_PCRE, AUXLIBS_PGSQL, AUXLIBS_SDBM,
39#	and AUXLIBS_SQLITE, respectively.
40# .IP \fBCC=\fIcompiler_command\fR
41#	Specifies a non-default compiler. On many systems, the default
42#	is \fBgcc\fR.
43# .IP \fBCCARGS=\fIcompiler_arguments\fR
44#	Specifies non-default compiler arguments, for example, a non-default
45#	\fIinclude\fR directory.
46#	The following directives are special:
47# .RS
48# .IP \fB-DNO_DB\fR
49#	Do not build with Berkeley DB support.
50# .IP \fB-DNO_DEVPOLL\fR
51#	Do not build with Solaris /dev/poll support.
52#	By default, /dev/poll support is compiled in on platforms that
53#	are known to support it.
54# .IP \fB-DNO_DNSSEC\fR
55#	Do not build with DNSSEC support, even if the resolver
56#	library appears to support it.
57# .IP \fB-DNO_EPOLL\fR
58#	Do not build with Linux EPOLL support.
59#	By default, EPOLL support is compiled in on platforms that
60#	are known to support it.
61# .IP \fB-DNO_EAI\fR
62#	Do not build with EAI (SMTPUTF8) support. By default, EAI
63#	support is compiled in when the "pkg-config" command is
64#	found, or the deprecated "icu-config" command.
65# .IP \fB-DNO_INLINE\fR
66#	Do not require support for C99 "inline" functions. Instead,
67#	implement argument typechecks for non-(printf/scanf)-like
68#	functions with ternary operators and unreachable code.
69# .IP \fB-DNO_IPV6\fR
70#	Do not build with IPv6 support.
71#	By default, IPv6 support is compiled in on platforms that
72#	are known to have IPv6 support.
73#
74#	Note: this directive is for debugging and testing only. It
75#	is not guaranteed to work on all platforms. If you don't
76#	want IPv6 support, set "inet_protocols = ipv4" in main.cf.
77# .IP \fB-DNO_IP_CYRUS_SASL_AUTH\fR
78#	Don't pass remote SMTP client and Postfix SMTP server IP
79#	address and port information to the Cyrus SASL library.
80#	This is compatible with Postfix < 3.2.
81# .IP \fB-DNO_KQUEUE\fR
82#	Do not build with FreeBSD/NetBSD/OpenBSD/MacOSX KQUEUE support.
83#	By default, KQUEUE support is compiled in on platforms that
84#	are known to support it.
85# .IP \fB-DNO_NIS\fR
86#	Do not build with NIS or NISPLUS support. Support for NIS
87#	is unavailable on some recent Linux distributions.
88# .IP \fB-DNO_NISPLUS\fR
89#	Do not build with NISPLUS support. Support for NISPLUS
90#	is unavailable on some recent Solaris distributions.
91# .IP \fB-DNO_PCRE\fR
92#	Do not build with PCRE support.
93#	By default, PCRE support is compiled in when the \fBpcre-config\fR
94#	utility is installed.
95# .IP \fB-DNO_POSIX_GETPW_R\fR
96#	Disable support for POSIX getpwnam_r/getpwuid_r.
97# .IP \fB-DNO_SIGSETJMP\fR
98#	Use setjmp()/longjmp() instead of sigsetjmp()/siglongjmp().
99#	By default, Postfix uses sigsetjmp()/siglongjmp() when they
100#	appear to work.
101# .IP \fB-DNO_SNPRINTF\fR
102#	Use sprintf() instead of snprintf(). By default, Postfix
103#	uses snprintf() except on ancient systems.
104# .RE
105# .IP \fBDEBUG=\fIdebug_level\fR
106#	Specifies a non-default debugging level. The default is \fB-g\fR.
107#	Specify \fBDEBUG=\fR to turn off debugging.
108# .IP \fBOPT=\fIoptimization_level\fR
109#	Specifies a non-default optimization level. The default is \fB-O\fR.
110#	Specify \fBOPT=\fR to turn off optimization.
111# .IP \fBPOSTFIX_INSTALL_OPTS=\fI-option...\fR
112#	Specifies options for the postfix-install command, separated
113#	by whitespace. Currently, the only supported option is
114#	\fB-keep-build-mtime\fR.
115# .IP \fBSHLIB_CFLAGS=\fIflags\fR
116#	Override the compiler flags (typically, "-fPIC") for Postfix
117#	dynamically-linked libraries and database plugins.
118#
119#	This feature was introduced with Postfix 3.0.
120# .IP \fBSHLIB_RPATH=\fIrpath\fR
121#	Override the runpath (typically, "'-Wl,-rpath,${SHLIB_DIR}'")
122#	for Postfix dynamically-linked libraries.
123#
124#	This feature was introduced with Postfix 3.0.
125# .IP \fBSHLIB_SUFFIX=\fIsuffix\fR
126#	Override the filename suffix (typically, ".so") for Postfix
127#	dynamically-linked libraries and database plugins.
128#
129#	This feature was introduced with Postfix 3.0.
130# .IP \fBshared=yes\fR
131# .IP \fBshared=no\fR
132#	Enable (disable) Postfix builds with dynamically-linked
133#	libraries typically named $shlib_directory/libpostfix-*.so.*.
134#
135#	This feature was introduced with Postfix 3.0.
136# .IP \fBdynamicmaps=yes\fR
137# .IP \fBdynamicmaps=no\fR
138#	Enable (disable) Postfix builds with the configuration file
139#	$meta_directory/dynamicmaps.cf and dynamically-loadable
140#	database plugins typically named postfix-*.so.*.  The setting
141#	"dynamicmaps=yes" implicitly enables Postfix dynamically-linked
142#	libraries.
143#
144#	This feature was introduced with Postfix 3.0.
145# .IP \fBpie=yes\fR
146# .IP \fBpie=no\fR
147#	Enable (disable) Postfix builds with position-independent
148#	executables, on platforms where this is supported.
149#
150#	This feature was introduced with Postfix 3.0.
151# .IP \fIinstallation_parameter\fB=\fIvalue\fR...
152#	Override the compiled-in default value of the specified
153#	installation parameter(s). The following parameters are
154#	supported in this context:
155#
156#	command_directory config_directory daemon_directory
157#	data_directory default_database_type html_directory
158#	mail_spool_directory mailq_path manpage_directory meta_directory
159#	newaliases_path queue_directory readme_directory sendmail_path
160#	shlib_directory openssl_path
161#
162#	See the postconf(5) manpage for a description of these
163#	parameters.
164#
165#	This feature was introduced with Postfix 3.0.
166# .IP \fBWARN=\fIwarning_flags\fR
167#	Specifies non-default gcc compiler warning options for use when
168#	"make" is invoked in a source subdirectory only.
