Tue Oct 14 10:19:18 1997 Gordon Matzigkeit <gord@gnu.org>
|
||||
|
||||
* ltmain.in (link): Added a bit more inter-language support to the
|
||||
symbol file generation process.
|
||||
|
||||
Thu Oct 9 12:56:13 1997 Gordon Matzigkeit <gord@gnu.ai.mit.edu>
|
||||
|
||||
* ltmain.in (link): Change the wrapper script to follow symlinks
|
||||
in order to find thisdir. This should put the final nail in the
|
||||
coffin for problems with wrapper scripts. From Ian Lance Taylor.
|
||||
|
||||
Tue Oct 7 10:49:29 1997 Gordon Matzigkeit <gord@gnu.ai.mit.edu>
|
||||
|
||||
* ltmain.in: Change a few `$echo' commands into `$show' to make
|
||||
--silent mode behave as advertised.
|
||||
|
||||
* ltconfig.in (allow_undefined_flag): On OSF/1 4.x, use
|
||||
`-expect_unresolved \*'. From Christian Mondrup.
|
||||
|
||||
* ltmain.in (install): Change install mode to allow a specified
|
||||
/bin/sh argument at the beginning of the install_prog. Also,
|
||||
specify the shell to run when invoking libtool recursively for
|
||||
finish mode. From Chris Provenzano.
|
||||
|
||||
* libtool.m4 (LIBTOOL): Change definition to include $(SHELL).
|
||||
From Chris Provenzano.
|
||||
|
||||
* ltconfig.in: Port to UTS 4.x. From Alistair Crooks.
|
||||
|
||||
* demo/Makefile.am (hc-libflag): Add rules to make this binary for
|
||||
hardcode.test.
|
||||
|
||||
Wed Sep 24 19:54:53 1997 Gordon Matzigkeit <gord@gnu.ai.mit.edu>
|
||||
|
||||
* ltconfig.in (LD): As with libtool.m4, don't override LD.
|
||||
Do a whole bunch of ac_t quoting.
|
||||
|
||||
Wed Sep 24 11:11:01 1997 Ian Lance Taylor <ian@cygnus.com>
|
||||
|
||||
* libtool.m4 (AM_PROG_LD): Don't override LD in the environment.
|
||||
|
||||
Sun Sep 21 13:13:06 1997 Gordon Matzigkeit <gord@gnu.ai.mit.edu>
|
||||
|
||||
* libtool.m4, ltconfig.in (NM): Arguments to the for loop must be
|
||||
whitespace separated. This fixes a bug under FreeBSD's /bin/sh.
|
||||
From George Scott.
|
||||
|
||||
Sat Sep 20 13:59:47 1997 Gordon Matzigkeit <gord@gnu.ai.mit.edu>
|
||||
|
||||
* ltmain.in (deplibs): When building shared libraries, always add
|
||||
-lc to deplibs. Reported by Andreas Jellinghaus.
|
||||
|
||||
Mon Sep 15 07:08:35 1997 Gordon Matzigkeit <gord@gnu.ai.mit.edu>
|
||||
|
||||
* ltconfig.in, ltmain.in (COLLECT_NAMES): If the COLLECT_NAMES
|
||||
environment variable has not been set, set it to empty. This
|
||||
apparently fixes the AIX bug with GCC's collect2. Reported by
|
||||
Mark Kettenis.
|
||||
|
||||
* demo/Makefile.am, ltmain.in, tests/hardcode.test (objdir):
|
||||
Changed objdir variable .libs to _libs. This is another MS-DOS
|
||||
portability fix. Suggested by Robert Hoehne.

Franc,ois Pinard about debugging:

``Another thing I'm curious to experiment is how will `gdb' perform

generating a "more easy to debug" version of the program. I tried the

recipe, but it broke somewhere in Automake generated dependency code,

so I got to remove it for now. However, the manual does not explain

what the debugging difficulty is, and so, I wonder what problems I

will meet.''
