# NAME

|
# makedefs 1
|
|
# SUMMARY
|
|
# 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.
|
|
#
|
|
# Default settings can be overruled by specifying them as
|
|
# environment variables. Use quotes if variables contain
|
|
# whitespace or shell meta characters.
|
|
# .IP \fBAUXLIBS=\fIobject_library...\fR
|
|
# Specifies one or more non-default object libraries.
|
|
# .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_IPV6\fR
|
|
# Do not build with IPv6 support.
|
|
# By default, IPv6 support is compiled in on platforms that
|
|
# are known to have IPv6 support.
|
|
# .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.
|
|
# .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 \fBWARN=\fIwarning_flags\fR
|
|
# Specifies non-default gcc compiler warning options for use when
|
|
# "make" is invoked in a source subdirectory only.
