From 481e3e83f6b71d6639dd5c3fbd3c0d1e1ac18328 Mon Sep 17 00:00:00 2001 From: Alexei Sheplyakov Date: Mon, 1 Dec 2008 10:12:25 +0100 Subject: [PATCH] [PATCH] Fix GiNaC library version information. The libtool naming scheme cannot guarantee that on all systems, the numbering is consecutive. It only guarantees that it is increasing. This doesn't matter, though: there is not incurred cost for numbers that are omitted, except for shrinking the available space of leftover numbers. Not something we need to worry about yet. ;-) On the other hand, tricks which we were using to make version numbers consecutive on GNU/Linux break versioning on other OSes. --- configure.ac | 37 +++++++++++++++++++++---------------- 1 file changed, 21 insertions(+), 16 deletions(-) diff --git a/configure.ac b/configure.ac index fff79dd0..78d7f2a6 100644 --- a/configure.ac +++ b/configure.ac @@ -1,22 +1,30 @@ dnl Process this file with autoconf to produce a configure script. -dnl GiNaC library version information. -dnl -dnl Making releases: -dnl ginac_micro_version += 1; -dnl ginac_interface_age += 1; -dnl ginac_binary_age += 1; -dnl if any functions have been added, set ginac_interface_age to 0. -dnl if backwards compatibility has been broken, -dnl set ginac_binary_age and ginac_interface_age to 0. - +dnl GiNaC version number m4_define([ginac_major_version], [1]) m4_define([ginac_minor_version], [5]) m4_define([ginac_micro_version], [0]) m4_define([ginac_version], [ginac_major_version.ginac_minor_version.ginac_micro_version]) m4_define([ginac_release], [ginac_major_version.ginac_minor_version]) -m4_define([ginac_interface_age], [0]) -m4_define([ginac_binary_age], [0]) + +dnl GiNaC library version information.
