hdf5iotest recipe does not compile with mpicc or supply libmpi to linker -> error adding symbols: DSO missing from command line

[Noerr]

Following the spack install instructions, I arrive at the following error regarding undefined reference to ompi_mpi_byte and libmpi.so.40: error adding symbols: DSO missing from command line If we look at the gcc command line it seem odd that neither mpicc is used or -lmpi is explicitly linked.

mv -f .deps/hdf5_iotest.Tpo .deps/hdf5_iotest.Po
mv -f .deps/write_test.Tpo .deps/write_test.Po

I was able to complete the build of hdf5_iotest executable by starting from this failed spack install, chdir into the /tmp spack build staging. Rexecute the final link command using mpicc.

Unlike other libraries, rpath doesn't get set so I have to set LD_LIBRARY_PATH

export LD_LIBRARY_PATH=/home/noah/spack/opt/spack/linux-ubuntu22.04-icelake/gcc-11.3.0/util-linux-uuid-2.38.1-mutzzr33dylliaew3ftjs2ksge4vtsmi/lib/:/home/noah/spack/opt/spack/linux-ubuntu22.04-icelake/gcc-11.3.0/hdf5-1.14.0-atpncwlkmdpd4ir53ladkxm2txpl77pr/lib/:${LD_LIBRARY_PATH}
