MAKEDEFS(1)                          General Commands Manual                          MAKEDEFS(1)

NAME
       makedefs - Postfix makefile configuration utility

SYNOPSIS
       make makefiles name=value...

DESCRIPTION
       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,  ma-
       jor.minor-date  for  a  development  release).   Do  not  try  to  specify  something like
       $mail_version: 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  AUXLIBS_CDB,  AUXLIBS_LDAP,
              AUXLIBS_LMDB,   AUXLIBS_MYSQL,   AUXLIBS_PCRE,   AUXLIBS_PGSQL,  AUXLIBS_SDBM,  and
              AUXLIBS_SQLITE, 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 direc-
              tory.  The following directives are special:

              -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 com-
                     piled in on platforms that are known to support it.

              -DNO_EAI
                     Do not build with EAI (SMTPUTF8) support. By default, EAI  support  is  com-
                     piled in when the "pkg-config" command is found, or the deprecated "icu-con-
                     fig" command.

              -DNO_INLINE
                     Do not require support for C99 "inline" functions. Instead, implement  argu-
                     ment 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  "inet_proto-
                     cols = ipv4" in main.cf.

              -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 pcre-config utility is 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()/siglongjmp().  By default,
                     Postfix uses sigsetjmp()/siglongjmp() when they appear to work.

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

       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. Cur-
              rently, the only supported option is -keep-build-mtime.

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

              This feature was introduced with Postfix 3.0.

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

              This feature was introduced with Postfix 3.0.

       SHLIB_SUFFIX=suffix
              Override the filename suffix (typically, ".so") for Postfix dynamically-linked  li-
              braries 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
              $shlib_directory/libpostfix-*.so.*.

              This feature was introduced with Postfix 3.0.

       dynamicmaps=yes

       dynamicmaps=no
              Enable (disable) Postfix builds with the configuration file  $meta_directory/dynam-
              icmaps.cf and dynamically-loadable database plugins typically named postfix-*.so.*.
              The setting "dynamicmaps=yes" implicitly  enables  Postfix  dynamically-linked  li-
              braries.

              This feature was introduced with Postfix 3.0.

       pie=yes

       pie=no Enable (disable) Postfix builds with position-independent executables, 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 installation  parameter(s).
              The following parameters are supported in this context:

              command_directory  config_directory  daemon_directory  data_directory default_data-
              base_type html_directory mail_spool_directory mailq_path manpage_directory meta_di-
              rectory newaliases_path queue_directory readme_directory sendmail_path shlib_direc-
              tory openssl_path

              See the postconf(5) manpage for a description of these parameters.

              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.
