[PATCH 1/9] libtool: add -shortname option |
Date: |
Sun, 4 Nov 2012 21:13:26 +0900 |
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: Add news for -shortname.
* build-aux/ltmain.in(func_mode_help): Add a description for -shortname.
(fund_mode_link): Add -shortname.
* doc/libtool.texi: Add -shortname item.
* m4/libtool.m4: Introduce shortname_cmds for -shortname.
