    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_ver-
           sion: 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_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.

           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 "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:

                  command_directory config_directory daemon_directory  data_direc-
                  tory  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  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.
