From c620c5dd4af864f8d70bbf78eaf0cb4743ca5594 Mon Sep 17 00:00:00 2001 From: KO Myung-Hun Date: Fri, 14 Jan 2011 00:43:38 +0900 Subject: [PATCH 01/10] Add -shortname option. OS/2 limits a length of a DLL base name up to 8 characters. If a name of a shared library is longer than 8 characters, OS/2 cannot load it. So the option to specify a short name is needed. --- NEWS | 1 + doc/libtool.texi | 4 ++++ libltdl/config/ltmain.m4sh | 11 +++++++++++ libltdl/m4/libtool.m4 | 38 ++++++++++++++++++++++++++++++++++---- 4 files changed, 50 insertions(+), 4 deletions(-) diff --git a/NEWS b/NEWS index 39eb771..895b77f 100644 --- a/NEWS +++ b/NEWS @@ -7,6 +7,7 @@ New in 2.4.2 2011-??-??: git version 2.4.1a, Libtool team: - The --with-pic configure option now supports a list of comma-separated package names.
