It's a Libtool issue (once again) which occurs if a previous build is re-
configured without subsequent "make clean" and the LIBC developer library
"libutil" is added to LIBS.
The error is simple to reproduce by the following steps:
2. make -C ompi/contrib/vt/vt/util
3. touch ompi/contrib/vt/vt/util/installdirs_conf.h # created by configure
4. make -C ompi/contrib/vt/vt/util
No such file or directory
make: *** [libutil.la] Error 9
When re-building the VT's libutil Libtool detects the system's libutil as
dependency and tries to find a corresponding Libtool library (*.la). And here
is the problem: Libtool finds ompi/contrib/vt/vt/util/libutil.la which is still
present from the previous build and has nothing to do with the system's
libutil. Afterwards, Libtool fails on extracting the archive
ompi/contrib/vt/vt/util/.libs/libutil.a which isn't present for any reason.
There are different ways to fix the problem:
1. Apply the attached patch on ltmain.sh.
This patch excludes the target library name from searching *.la libraries.
2. Rename the VT's libutil
This would prevents name conflicts with dependency libraries.
3. Clear list of dependency libraries when building VT's libutil.
This could be done by adding LIBS= to the Makefile.am in
ompi/contrib/vt/vt/util/. The VT's libutil has no dependencies to other
libraries except libc.
4. Perform "make clean" or remove ompi/contrib/vt/vt/util/libutil.la after re-
Nonsense - it cannot be required from the user.
My favorite suggestion is 1. It would be just another patch in addition to the
set of Libtool patches invoked by autogen.
What do you think?
