HEAD testsuite.
Hi all... Could it be, that the autotest testsuite behaves badly if building out-of-source? I'm getting a whole bunch of file not founds with relative paths within the source dir.

Native Windows through parity
Hi there (again :))! I have a few patches for libtool in my queue again :) * 1.5.24 -> all tests passed * 1.5.26 -> all tests passed * HEAD (2.1c) -> all classic tests passed, log for new testsuite attached. I hope this time they will make it into CVS :) For HEAD, I'd need some help, please. I attached the log for test no. 5, which fails like some others too with file not found errors which I don't understand... (?) any ideas? Note: I have chosen the *-*-winnt* host-triplet for my setup, since the resulting binaries are plain native windows, so I think this is correct. Also right now I'm the only one doing this, and as far as I know, there are no collissions with others. Note: I needed to patch config.guess to recognize my compiler on interix (cygwin not done yet...). I did this for various automake releases and the gnuconfig package from portage (did you know, that portage runs on interix fine allready? :) I made a port of gentoo/alt-prefix). I attached only the automake 1.10 patch, which should make obvious what I did there. Of course this patch is not targeted at libtool, I attached it here only, since it's a prerequisite to make things work on interix... Please could somebody review the patches and the testsuite log (which is more important for me right now :)), and give me some feedback? Thanks in advance!

Libtool does not know about the system you are building for, does not
know that an underscore is required.
What is the host triplet for the system that you are building for?
You need to set archive_expsym_cmds for that system to be similar to
interix[[3-9]]* which has:
_LT_AC_TAGVAR(archive_expsym_cmds, $1)='sed "s,^,_," $export_symbols
>$output_objdir/$soname.expsym~$CC -shared $pic_flag $libobjs $deplibs
$compiler_flags ${wl}-h,$soname
${wl}--retain-symbols-file,$output_objdir/$soname.expsym
${wl}--image-base,`expr ${RANDOM-$$} % 4096 / 2 \* 262144 + 1342177280`
-o $lib'
As you can see, it takes the symbol list, prepends and underscore, and
then uses that.
It is not required to change global_symbol_pipe etc.

Sun Studio: STL libraries
In trying to resolve a C++ issue within Open MPI we've run into an issue with Libtool automatically linking in Cstd. Because Sun Studio supports two different types of C++ STL libraries (Cstl and stlport4) we needed to remove Open MPI's reliance on STL functions so applications being compiled with Sun Studio could use either version of STL libraries (note once you link with one you cannot use the other STL library). After making Open MPI STL agnostic we found out that libtool is automatically adding in "-lCstd -lCrun" to CXXFLAGS which is causing our fix to make Open MPI STL agnostic useless. We currently are hacking aclocal's LT macros to *not* add the Cstd library to any of OMPI's CXXFLAGS to work around this issue. We are wondering if there is a way libtool could remove the addition of -lCstd and -lCrun to CXXFLAGS when it detects Sun Studio Compilers being used? ___ http://lists.gnu.org/mailman/listinfo/libtool

The strange thing is that libtool checks if global_symbol_pipe
needs to handle underscore with a general check, not with
a host name check.
But this knowledge is not used for archive_expsym_cmds.
For blackfin the only difference is undescore, otherwise it
looks like regular linux. So special casing bfin-linux looks
excessive. But if this okay with libtool maintainers, I may
try to create a patch that does exactly that.

Blackfin is not the only target that utilizes underscore prefixes. a more
generic check (as noted in the previous thread you cited) would be to
consider the define from gcc __USER_LABEL_PREFIX__.

_LT_ENABLE_FAST_INSTALL being expanded multiple times.
Hi, When building ImageMagick on Mac OS X, and installing with DESTDIR Jochem Huhmann of the MacPorts project noticed that the wrapper scripts were being installed, and the binaries not. I expect on darwin that fast_install always be set to needless, eliminating the need for relinking, however, with libtool HEAD, it gets set to needless, then if your configure.ac contains both LT_INIT and next LTDL_INIT, it gets set back to 'no' again. Both LT_INIT and LTDL_INIT expand _LT_SET_OPTIONS, which duly expands _LT_ENABLE_FAST_INSTALL *twice*. _LT_SET_OPTIONS should only set the default options once (and only for LT_INIT).

I still maintain that it would be OK to have libtool automatically add
`-library=Crun', since that is generally needed whether you're using
-library=stlport4 or -library=Cstd, but it's OK to not include that. We
just need to make sure the correct usage is documented somewhere.
If it's not currently documented (I don't know, I haven't checked the 2.x
series), I would be willing to write a little blurb for the info files

Debugging Libtool's Insistence on Sourcing a Library from /usr/lib Rather Than LDFLAGS
I am attempting to debug an issue involving libtool from the avahi-0.6.22
package sourcing the local (i686-unknown-linux-gnu) version of libexpat
(-lexpat) rather than the I one I direct it to find via LDFLAGS.

The most obvious potential problem was that
"/tmp/src/results/avahi/../expat/usr/lib" did not exist or contain the
desired libraries at the time of build or configuration; however, I have
verified that the directory and libraries are, in fact, there.
Another potential issue would be -L/usr/lib¹ getting in the argument list
ahead of -L/tmp/src/results/avahi/../expat/usr/lib¹. However, that doesn¹t
seem to be the case either.
If I pass --debug¹ to libtool, it seems to find the correct
/tmp/src/results/avahi/../expat/usr/lib/libexpat.la¹ file; however, it
latter seems to ignore that and pick-up /usr/lib/libexpat.so¹ anyway:

Re: GNU Libtool 2.1b released (alpha release)
Quoting "Gary V. Vaughan" <[EMAIL PROTECTED]>: With only one bug reported and fixed since Feb 1, either this is the most spectacularly well engineered release in the history of libtool, or else it is the least well tested release ever... For what it's worth, swfdec and swfdec-mozilla are fine with libtool CVS trunk. Even "make distcheck" passes. x86_64, Fedora 8 with all updates.
