# NAME
# makedefs 1
# SUMMARY
# Postfix makefile configuration utility
# SYNOPSIS
# \fBmake makefiles \fIname=value...\fR
# DESCRIPTION
# The \fBmakedefs\fR 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.
#
# 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 parameter value with
# the Postfix release version. Do not try to specify something
# like $mail_version on this command line. This produces
# inconsistent results with different versions of the make(1)
# command.
# .IP \fBAUXLIBS=\fIobject_library...\fR
# Specifies one or more non-default object libraries. Postfix
# 2,12 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.
# .IP \fBCC=\fIcompiler_command\fR
# Specifies a non-default compiler. On many systems, the default
# is \fBgcc\fR.
# .IP \fBCCARGS=\fIcompiler_arguments\fR
# Specifies non-default compiler arguments, for example, a non-default
# \fIinclude\fR directory.
# The following directives are special:
# .RS
# .IP \fB-DNO_DB\fR
# Do not build with Berkeley DB support.
# .IP \fB-DNO_DEVPOLL\fR
# Do not build with Solaris /dev/poll support.
# By default, /dev/poll support is compiled in on platforms that
# are known to support it.
# .IP \fB-DNO_DNSSEC\fR
# Do not build with DNSSEC support, even if the resolver
# library appears to support it.
# .IP \fB-DNO_EPOLL\fR
# Do not build with Linux EPOLL support.
# By default, EPOLL support is compiled in on platforms that
# are known to support it.
# .IP \fB-DNO_EAI\fR
# Do not build with EAI (SMTPUTF8) support. By default, EAI
# support is compiled in when the "icuuc" library and header
# files are found.
# .IP \fB-DNO_INLINE\fR
# Do not require support for C99 "inline" functions. Instead,
# implement argument typechecks for non-printf/scanf-like
# functions with ternary operators and unreachable code.
# .IP \fB-DNO_IPV6\fR
# 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.
# .IP \fB-DNO_KQUEUE\fR
# 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.
# .IP \fB-DNO_NIS\fR
# Do not build with NIS or NISPLUS support. Support for NIS
# is unavailable on some recent Linux distributions.
# .IP \fB-DNO_NISPLUS\fR
# Do not build with NISPLUS support. Support for NISPLUS
# is unavailable on some recent Solaris distributions.
# .IP \fB-DNO_PCRE\fR
# Do not build with PCRE support.
# By default, PCRE support is compiled in when the \fBpcre-config\fR
# utility is installed.
# .IP \fB-DNO_POSIX_GETPW_R\fR
# Disable support for POSIX getpwnam_r/getpwuid_r.
# .IP \fB-DNO_SIGSETJMP\fR
# Use setjmp()/longjmp() instead of sigsetjmp()/siglongjmp().
# By default, Postfix uses sigsetjmp()/siglongjmp() when they
# appear to work.
# .RE
# .IP \fBDEBUG=\fIdebug_level\fR
# Specifies a non-default debugging level. The default is \fB-g\fR.
# Specify \fBDEBUG=\fR to turn off debugging.
# .IP \fBOPT=\fIoptimization_level\fR
# Specifies a non-default optimization level. The default is \fB-O\fR.
# Specify \fBOPT=\fR to turn off optimization.
# .IP \fBSHLIB_CFLAGS=\fIflags\fR
# Override the compiler flags (typically, "-fPIC") for Postfix
# dynamically-linked libraries and database plugins.
#
# This feature was introduced with Postfix 3.0.
# .IP \fBSHLIB_RPATH=\fIrpath\fR
# Override the runpath (typically, "'-Wl,-rpath,${SHLIB_DIR}'")
# for Postfix dynamically-linked libraries.
#
# This feature was introduced with Postfix 3.0.
# .IP \fBSHLIB_SUFFIX=\fIsuffix\fR
# Override the filename suffix (typically, ".so") for Postfix
# dynamically-linked libraries and database plugins.
#
# This feature was introduced with Postfix 3.0.
# .IP \fBshared=yes\fR
# .IP \fBshared=no\fR
# Enable (disable) Postfix builds with dynamically-linked
# libraries typically named $shlib_directory/libpostfix-*.so.*.
#
# This feature was introduced with Postfix 3.0.
# .IP \fBdynamicmaps=yes\fR
# .IP \fBdynamicmaps=no\fR
# 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.
# .IP \fBpie=yes\fR
# .IP \fBpie=no\fR
#
# Enable (disable) Postfix builds with position-independent
# executables, on platforms where this is supported.
#
# This feature was introduced with Postfix 3.0.
# .IP \fIinstallation_parameter\fB=\fIvalue\fR...
# 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.
# .IP \fBWARN=\fIwarning_flags\fR
# Specifies non-default gcc compiler warning options for use when
# "make" is invoked in a source subdirectory only.
