Package: libopenmpi-dev Version: 4.1.6-13.3 When I attempt to run the mesonbuild testsuite as downloaded from https://github.com/mesonbuild/meson, using the following command:
./run_project_tests.py -v --only frameworks/17
it is intended to test that meson can detect openmpi and build a dummy
project against it.
Instead I get this error:
(inprocess) $ setup --prefix /usr --libdir lib 'test cases/frameworks/17
mpi' '/meson/b 6903cddbd2' --backend=ninja -Dmethod=pkg-config

Let's see the link flags it finds:
$ pkg-config --libs ompi-fort
-L/usr/lib/x86_64-linux-gnu/openmpi/lib/../../fortran/gfortran
-L/usr/lib/x86_64-linux-gnu/openmpi/lib -lmpi_usempif08
-lmpi_usempi_ignore_tkr -lmpi_mpifh -lmpi
This says to link against:
$ realpath
/usr/lib/x86_64-linux-gnu/openmpi/lib/../../fortran/gfortran/libmpi_mpifh.so
/usr/lib/x86_64-linux-gnu/libmpi_mpifh-gfortran.so.40.30.0
which in turn does not contain the desired symbols:
$ nm -D /usr/lib/x86_64-linux-gnu/libmpi_mpifh-gfortran.so.40.30.0
w _ITM_deregisterTMCloneTable
w _ITM_registerTMCloneTable
w __cxa_finalize
w __gmon_start__
In fact, I wonder what this library exists for at all. It's not a valid
library for building openmpi software against. It doesn't appear to be
installed by any other distros. It seems like it is something Debian has
patched in, but I cannot figure out why.
