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
pcre2-config or pcre-config utility 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()/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.
