Well this is disappointing. :-\

Can you "make V=1" so that we can see the command line here that is failing?

FWIW, this looks like a problem that is self-contained in VampirTrace, so you can likely get a working build with:

./configure --enable-contrib-no-build=vt ...

That's a weird one -- it should be *creating* that library, so I'm not sure why it would complain that the library doesn't exist...? This could be a red herring, though -- perhaps some oddity in your tree and/or filesystem...? (I've seen this kind of thing before such that a "make distclean" fixed the issue, I think)

Sure enough, using a new build directory, I get the same error as above:

libtool: link: clang++ -DVT_MPI -O3 -DNDEBUG -finline-functions -pthread -o .libs/vtunify-mpi vtunify_mpi-vt_unify_mpi.o vtunify_mpi-vt_unify.o vtunif

Grab config.log for this case here:

Same error. Weird. Can you "make V=1" here, too?
