#!/bin/sh #++ # NAME # makedefs 1 # SUMMARY # makefile configuration utility # SYNOPSIS # \fBmakedefs\fR # DESCRIPTION # The \fBmakedefs\fR command identifies the program 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. # .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. # LICENSE # .ad # .fi # The Secure Mailer license must be distributed with this software. # AUTHOR(S) # Wietse Venema # IBM T.J.
