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 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.

       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.
