<a name="name">NAME</a>
 makedefs - Postfix makefile configuration utility

<a name="synopsis">SYNOPSIS</a>
 make makefiles name=value...

<a name="description">DESCRIPTION</a>
 The makedefs 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.

NAME=VALUE OVERRIDES
 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 "make makefiles name=value..." will replace the string
 MAIL_VERSION at the end of a value with the Postfix version
 (major.minor.patchlevel for a stable release, major.minor-date for a
 development release). Do not try to specify something like $<a href="postconf.5.html#mail_version">mail_ver</a>-
 <a href="postconf.5.html#mail_version">sion</a>: that produces inconsistent results with different implementations
 of the make(1) command.

 AUXLIBS=object_library...
 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.

 CC=compiler_command
 Specifies a non-default compiler. On many systems, the default
 is gcc.

 CCARGS=compiler_arguments
 Specifies non-default compiler arguments, for example, a
 non-default include directory. The following directives are
 special:

 -DNO_CLOSEFROM
 Do not use the system closefom() implementation.

 -DNO_DB
 Do not build with Berkeley DB support.

 -DNO_DEVPOLL
 Do not build with Solaris /dev/poll support. By default,
 /dev/poll support is compiled in on platforms that are
 known to support it.

 -DNO_DNSSEC
 Do not build with DNSSEC support, even if the resolver
 library appears to support it.

 -DNO_EPOLL
 Do not build with Linux EPOLL support. By default, EPOLL
 support is compiled in on platforms that are known to
 support it.

 -DNO_EAI
 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.

 -DNO_INLINE
 Do not require support for C99 "inline" functions.
 Instead, implement argument typechecks for
 non-(printf/scanf)-like functions with ternary operators
 and unreachable code.

 -DNO_IPV6
 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>.

 -DNO_IP_CYRUS_SASL_AUTH
 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.

 -DNO_KQUEUE
 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.

 -DNO_NIS
 Do not build with NIS or NISPLUS support. Support for NIS
 is unavailable on some recent Linux distributions.

 -DNO_NISPLUS
 Do not build with NISPLUS support. Support for NISPLUS is
 unavailable on some recent Solaris distributions.

 -DNO_PCRE
 Do not build with PCRE support. By default, PCRE support
 is compiled in when the pcre2-config or pcre-config util-
 ity are installed.

 -DNO_POSIX_GETPW_R
 Disable support for POSIX getpwnam_r/getpwuid_r.

 -DNO_RES_NCALLS
 Do not build with the threadsafe resolver(5) API
 (res_ninit() etc.).

 -DNO_SIGSETJMP
 Use setjmp()/longjmp() instead of sigsetjmp()/sig-
 longjmp(). By default, Postfix uses sigsetjmp()/sig-
 longjmp() when they appear to work.

 -DNO_SNPRINTF
 Use sprintf() instead of snprintf(). By default, Postfix
 uses snprintf() except on ancient systems.

 -DNO_STDBOOL
 Don't use <stdbool.h>. This is usually auto-detected.

 DEBUG=debug_level
 Specifies a non-default debugging level. The default is -g.
 Specify DEBUG= to turn off debugging.

 OPT=optimization_level
 Specifies a non-default optimization level. The default is -O.
 Specify OPT= to turn off optimization.

 POSTFIX_INSTALL_OPTS=-option...
 Specifies options for the postfix-install command, separated by
 whitespace. Currently, the only supported option is
 -keep-build-mtime.

 SHLIB_CFLAGS=flags
 Override the compiler flags (typically, "-fPIC") for Postfix
 dynamically-linked libraries and database plugins.

 This feature was introduced with Postfix 3.0.

 SHLIB_RPATH=rpath
 Override the runpath (typically, "'-Wl,-rpath,${SHLIB_DIR}'")
 for Postfix dynamically-linked libraries.

 This feature was introduced with Postfix 3.0.

 SHLIB_SUFFIX=suffix
 Override the filename suffix (typically, ".so") for Postfix
 dynamically-linked libraries and database plugins.

 This feature was introduced with Postfix 3.0.

 shared=yes

 shared=no
 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.

 dynamicmaps=yes

 dynamicmaps=no
 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.

 pie=yes

 pie=no Enable (disable) Postfix builds with position-independent exe-
 cutables, on platforms where this is supported.

 This feature was introduced with Postfix 3.0.

 installation_parameter=value...
 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_cache_db_type">default_cache_db_type</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.

 WARN=warning_flags
 Specifies non-default gcc compiler warning options for use when
 "make" is invoked in a source subdirectory only.
