Hi Ralf, thank you for spending your time resolving my problem.
> First, a note to your Makefile: > > | ${LIB_A}: ${OBJS_A} > | libtool --mode=link ${CC} -o $@ $^ -static > | > | # -rpath is mandatory, libtool --mode=install will fail otherwise. > | ${LIB_SO}: ${OBJS_SO} > | libtool --mode=link ${CC} -o $@ $^ -version-number ${VERSION} > -rpath ${DESTDIR}/usr/lib > > You don't need both of these rules.

Note as far as I read the documentation, this is not explicitely explained that compiling a shared library also produces a static one. > You should really omit $(DESTDIR) in -rpath here (but not in the install > rules)! Done, I didn't know that. > I'd also write > > | clean: > | $(LIBTOOL) --mode=clean /bin/rm $(OBJS_SO) > > which should remove all your built objects Ok, I didn't know that too :-). I've had a look through the documentation, it would be worth to give an example of the use of this mode, IMHO. > Now back to the problem: Show > > $ libtool --config > $ libtool --features > > for both versions. Next question might be that I'd like you to try > 1.5.18, in order to prevent any known regressions from skewing what we > see here (unless it's obvious from above output what's happening here). > If you do build 1.5.18 yourself, show output of its configure run plus > config.log as well. Note that both version of libtool I use actually are issued from Debian unstable (sid). Package "libtool1.4" provides libtool-1.4.3 and package "libtool" provides libtool-1.5.6. They are mutually exclusive. I'm building libtool-1.5.18 using the debian/ directory from the libtool package. The typescript of package building is attached too ; FYI, the configure script output begins at line 91 and ends at about line 370. While here, I got --config and --features from the latter too. I didn't attached everything though, to avoid flooding the mail server, please look at the following URLs : http://tataz.chchile.org/~tataz/libtool/libtool-1.4.3--config http://tataz.chchile.org/~tataz/libtool/libtool-1.4.3--features http://tataz.chchile.org/~tataz/libtool/libtool-1.5.6--config http://tataz.chchile.org/~tataz/libtool/libtool-1.5.6--features http://tataz.chchile.org/~tataz/libtool/libtool-1.5.18--config http://tataz.chchile.org/~tataz/libtool/libtool-1.5.18--features http://tataz.chchile.org/~tataz/libtool/libtool-1.5.18.build.typescript I think I got my problem resolved by using the lastest version of libtool (1.5.18) : with exactly the same command sequence, I get a static library with libtool-1.5.18 in the .libs/ directory, while libtool-1.5.6 doesn't produce it. Is it a known behaviour ? Are there any workaround to this, except upgrading my libtool version (we have our own Debian distribution at work, and upgrading a package in it is, unfortunately, a heavy process, especially when the package is still not released by the Debian maintainer) ? If there isn't, I would send a notice to the Debian maintainer to let him know about this bug. Thanks again.
