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, major.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 directory.  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 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
                     "pkg-config" command is found, or the deprecated "icu-config" command.

              -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 "inet_protocols = 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_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() except 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.  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
              $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/dynamicmaps.cf and
              dynamically-loadable   database   plugins   typically   named   postfix-*.so.*.     The    setting
              "dynamicmaps=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 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_database_type
              html_directory mail_spool_directory mailq_path  manpage_directory  meta_directory  newaliases_path
              queue_directory readme_directory sendmail_path shlib_directory 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.
