- Synopsis
AC_DEFINE_VERSIONLEVEL(VARNAME [,VERSION [, DESCRIPTION]])- Version
1.2 (2001/11/02) guidod @ ac-archive-0.5.39
- Author
Guido Draheim <guidod@gmx.de>
- Description
if the VERSION is ommitted, shellvar $VERSION is used as defined by AM_INIT_AUTOMAKE's second argument.
The versionlevel is the numeric representation of the given version string, thereby assuming the inputversion is a string with (maximal) three decimal numbers seperated by "."-dots. A "-patch" adds a percent.
typical usage: AM_INIT_AUTOMAKE(mypkg,4.12.3) AC_DEFINE_VERSIONLEVEL(MYPKG_VERSION)
the config.h created from autoheader's config.h.in will contain... /* mypkg versionlevel */ #define MYPKG_VERSION 4120003
the MYKG_VERSION will be defined as both a shell-variable and AC_DEFINE
