From f2f67dde5c9caca69137da2178118407f27639ef Mon Sep 17 00:00:00 2001 From: Richard Kreckel Date: Tue, 29 Sep 2009 22:08:11 +0200 Subject: [PATCH 1/1] Properly document how to deal with libtool versioning. The old description was referring to ginac_lt_age which should always stay 0, because we promised to mark incompatible binary interfaces by bumping ginac_minor_version (or even ginac_major_version). Let's get rid of ginac_lt_age. --- configure.ac | 24 ++++++++++-------------- 1 file changed, 10 insertions(+), 14 deletions(-) diff --git a/configure.ac b/configure.ac index 565f4e63..fc0083f1 100644 --- a/configure.ac +++ b/configure.ac @@ -12,12 +12,11 @@ dnl version number.
