[PATCH 1/8] libtool: add -os2dllname option |
Date: |
Thu, 18 Sep 2014 11:56:58 +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 OS/2 DLL name shorter than 8 characters is needed.
As well as, OS/2 does not allow OS/2 DLL name to contain '.'.
* NEWS: Add news for -os2dllname.
* build-aux/ltmain.in (func_mode_help): Add a description for -os2dllname.
(fund_mode_link): Add -os2dllname.
* doc/libtool.texi: Add -os2dllname item.
* m4/libtool.m4: Introduce os2dllname_cmds for -os2dllname.
