<b><a name="name">NAME</a></b>
makedefs - Postfix makefile configuration utility
<b><a name="synopsis">SYNOPSIS</a></b>
<b>make makefiles</b> <i>name=value...</i>
<b><a name="description">DESCRIPTION</a></b>
The <b>makedefs</b> command identifies the compilation environment, and emits
macro definitions on the standard output stream that can be prepended
to template Makefiles. These macros implement an internal interface
and are subject to change without notice.
<b>NAME=VALUE OVERRIDES</b>
Default settings can be overruled by specifying them as environment
variables (or as name=value pairs on the "make" command line). Use
quotes if variables contain whitespace or shell meta characters.
The command "<b>make makefiles name=value...</b>" will replace the string
<b>MAIL_VERSION</b> at the end of a value with the Postfix version
(<i>major.minor.patchlevel</i> for a stable release, <i>major.minor-date</i> for a
development release). Do not try to specify something like <b>$<a href="postconf.5.html#mail_version">mail_ver</a>-</b>
<b><a href="postconf.5.html#mail_version">sion</a></b>: that produces inconsistent results with different implementations
of the make(1) command.
<b>AUXLIBS=</b><i>object</i><b>_</b><i>library...</i>
Specifies one or more non-default object libraries. Postfix 3.0
and later specify some of their database library dependencies
with <a href="CDB_README.html">AUXLIBS_CDB</a>, <a href="LDAP_README.html">AUXLIBS_LDAP</a>, <a href="LMDB_README.html">AUXLIBS_LMDB</a>, <a href="MONGODB_README.html">AUXLIBS_MONGODB</a>,
<a href="MYSQL_README.html">AUXLIBS_MYSQL</a>, <a href="PCRE_README.html">AUXLIBS_PCRE</a>, <a href="PGSQL_README.html">AUXLIBS_PGSQL</a>, AUXLIBS_SDBM, and
<a href="SQLITE_README.html">AUXLIBS_SQLITE</a>, respectively.
<b>CC=</b><i>compiler</i><b>_</b><i>command</i>
Specifies a non-default compiler. On many systems, the default
is <b>gcc</b>.
<b>CCARGS=</b><i>compiler</i><b>_</b><i>arguments</i>
Specifies non-default compiler arguments, for example, a
non-default <i>include</i> directory. The following directives are
special:
<b>-DNO_CLOSEFROM</b>
Do not use the system closefom() implementation.
<b>-DNO_DB</b>
Do not build with Berkeley DB support.
<b>-DNO_DEVPOLL</b>
Do not build with Solaris /dev/poll support. By default,
/dev/poll support is compiled in on platforms that are
known to support it.
<b>-DNO_DNSSEC</b>
Do not build with DNSSEC support, even if the resolver
library appears to support it.
<b>-DNO_EPOLL</b>
Do not build with Linux EPOLL support. By default, EPOLL
support is compiled in on platforms that are known to
support it.
<b>-DNO_EAI</b>
Do not build with EAI (SMTPUTF8) support. By default, EAI
support is compiled in when the "pkgconf" or "pkg-config"
command are found, or the deprecated "icu-config" com-
mand.
<b>-DNO_INLINE</b>
Do not require support for C99 "inline" functions.
Instead, implement argument typechecks for
non-(printf/scanf)-like functions with ternary operators
and unreachable code.
<b>-DNO_IPV6</b>
Do not build with IPv6 support. By default, IPv6 support
is compiled in on platforms that are known to have IPv6
support.
Note: this directive is for debugging and testing only.
It is not guaranteed to work on all platforms. If you
don't want IPv6 support, set "<a href="postconf.5.html#inet_protocols">inet_protocols</a> = ipv4" in
<a href="postconf.5.html">main.cf</a>.
<b>-DNO_IP_CYRUS_SASL_AUTH</b>
Don't pass remote SMTP client and Postfix SMTP server IP
address and port information to the Cyrus SASL library.
This is compatible with Postfix < 3.2.
<b>-DNO_KQUEUE</b>
Do not build with FreeBSD/NetBSD/OpenBSD/MacOSX KQUEUE
support. By default, KQUEUE support is compiled in on
platforms that are known to support it.
<b>-DNO_NIS</b>
Do not build with NIS or NISPLUS support. Support for NIS
is unavailable on some recent Linux distributions.
<b>-DNO_NISPLUS</b>
Do not build with NISPLUS support. Support for NISPLUS is
unavailable on some recent Solaris distributions.
<b>-DNO_PCRE</b>
Do not build with PCRE support. By default, PCRE support
is compiled in when the <b>pcre2-config</b> or <b>pcre-config</b> util-
ity are installed.
<b>-DNO_POSIX_GETPW_R</b>
Disable support for POSIX getpwnam_r/getpwuid_r.
<b>-DNO_RES_NCALLS</b>
Do not build with the threadsafe resolver(5) API
(res_ninit() etc.).
<b>-DNO_SIGSETJMP</b>
Use setjmp()/longjmp() instead of sigsetjmp()/sig-
longjmp(). By default, Postfix uses sigsetjmp()/sig-
longjmp() when they appear to work.
<b>-DNO_SNPRINTF</b>
Use sprintf() instead of snprintf(). By default, Postfix
uses snprintf() except on ancient systems.
<b>DEBUG=</b><i>debug</i><b>_</b><i>level</i>
Specifies a non-default debugging level. The default is <b>-g</b>.
Specify <b>DEBUG=</b> to turn off debugging.
<b>OPT=</b><i>optimization</i><b>_</b><i>level</i>
Specifies a non-default optimization level. The default is <b>-O</b>.
Specify <b>OPT=</b> to turn off optimization.
<b>POSTFIX_INSTALL_OPTS=</b><i>-option...</i>
Specifies options for the postfix-install command, separated by
whitespace. Currently, the only supported option is
<b>-keep-build-mtime</b>.
<b>SHLIB_CFLAGS=</b><i>flags</i>
Override the compiler flags (typically, "-fPIC") for Postfix
dynamically-linked libraries and database plugins.
This feature was introduced with Postfix 3.0.
<b>SHLIB_RPATH=</b><i>rpath</i>
Override the runpath (typically, "'-Wl,-rpath,${SHLIB_DIR}'")
for Postfix dynamically-linked libraries.
This feature was introduced with Postfix 3.0.
<b>SHLIB_SUFFIX=</b><i>suffix</i>
Override the filename suffix (typically, ".so") for Postfix
dynamically-linked libraries and database plugins.
This feature was introduced with Postfix 3.0.
<b>shared=yes</b>
<b>shared=no</b>
Enable (disable) Postfix builds with dynamically-linked
libraries typically named $<a href="postconf.5.html#shlib_directory">shlib_directory</a>/libpostfix-*.so.*.
This feature was introduced with Postfix 3.0.
<b>dynamicmaps=yes</b>
<b>dynamicmaps=no</b>
Enable (disable) Postfix builds with the configuration file
$<a href="postconf.5.html#meta_directory">meta_directory</a>/dynamicmaps.cf and dynamically-loadable database
plugins typically named postfix-*.so.*. The setting "dynam-
icmaps=yes" implicitly enables Postfix dynamically-linked
libraries.
This feature was introduced with Postfix 3.0.
<b>pie=yes</b>
<b>pie=no</b> Enable (disable) Postfix builds with position-independent exe-
cutables, on platforms where this is supported.
This feature was introduced with Postfix 3.0.
<i>installation</i><b>_</b><i>parameter</i><b>=</b><i>value</i>...
Override the compiled-in default value of the specified instal-
lation parameter(s). The following parameters are supported in
this context:
<a href="postconf.5.html#command_directory">command_directory</a> <a href="postconf.5.html#config_directory">config_directory</a> <a href="postconf.5.html#daemon_directory">daemon_directory</a> <a href="postconf.5.html#data_directory">data_direc</a>-
<a href="postconf.5.html#data_directory">tory</a> <a href="postconf.5.html#default_database_type">default_database_type</a> <a href="postconf.5.html#html_directory">html_directory</a> <a href="postconf.5.html#mail_spool_directory">mail_spool_directory</a>
<a href="postconf.5.html#mailq_path">mailq_path</a> <a href="postconf.5.html#manpage_directory">manpage_directory</a> <a href="postconf.5.html#meta_directory">meta_directory</a> <a href="postconf.5.html#newaliases_path">newaliases_path</a>
<a href="postconf.5.html#queue_directory">queue_directory</a> <a href="postconf.5.html#readme_directory">readme_directory</a> <a href="postconf.5.html#sendmail_path">sendmail_path</a> <a href="postconf.5.html#shlib_directory">shlib_directory</a>
<a href="postconf.5.html#openssl_path">openssl_path</a>
See the <a href="postconf.5.html">postconf(5)</a> manpage for a description of these parame-
ters.
This feature was introduced with Postfix 3.0.
<b>WARN=</b><i>warning</i><b>_</b><i>flags</i>
Specifies non-default gcc compiler warning options for use when
"make" is invoked in a source subdirectory only.
