Hi there,
The current libtool, both -rHEAD and -rmulti-language-branch, ever since 1999-
10-01 in fact, causes catastrophic breakage on standard UNIX systems on which
archives created by ar MUST be ranlib'ed before ld can use them at all (at
least 4.0BSD through 4.3BSD, and lots of others I'm sure). I have traced the
breakage down to this change:
1999-10-01 Gary V. Vaughan <[EMAIL PROTECTED]>
* configure.in (AC_OUTPUT_COMMANDS): generate ltmain.sh
* Makefile.am (ltmain.sh ltconfig): removed. Automake inserts the
rules to automatically call config.status.
* libtool.m4: be sure to AC_SUBST values no longer tested in
ltconfig.in.
* ltconfig.in: replaced several of the simple feature tests with
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
substitutions from config.status.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
* Makefile.am (ltconfig): generate ltconfig with config.status.
* configure.in (AC_OUTPUT): generate ltconfig with config.status.
especially the highlighted part.
Before this change, ltconfig.in contained the following code:
if test -n "$ac_cv_prog_RANLIB"; then
RANLIB="$ac_cv_prog_RANLIB"
old_archive_cmds="$old_archive_cmds~\$RANLIB \$oldlib"
old_postinstall_cmds="\$RANLIB \$oldlib~$old_postinstall_cmds"
echo "$ac_t$RANLIB" 1>&6
else
echo "$ac_t""no" 1>&6
fi
Gary's change removed this code and switched to configure's standard ranlib
check. But this is more than just a standard configure check! See how it adds
ranlib commands to old_archive_cmds and old_postinstall_cmds. After Gary's
change old_archive_cmds and old_postinstall_cmds never contain ranlib commands.
As a result, the archive is built with ar but not ranlib'ed, causing
catastrophic breakage on all standard UNIX systems on which archives created by
ar must be ranlib'ed before ld can use them.
The breakage caused by this change currently exists on both -rHEAD and -rmulti-
language-branch and needs to be fixed in both places. However, I'm not sure
what's the right way to fix this in the current libtool given all the changes
since then. Can someone please fix this? TIA.
