[Pkg-openmpi-maintainers] Bug#865471: libopenmpi2: Missing Symlinks to Open MPI Libraries

[Ron Lovell]

Package: libopenmpi2
Version: 2.1.1-4
Severity: important
Tags: newcomer

Dear Maintainer,

After upgrade to libopenmpi2_2.1.1-4_amd64, libopenmpi-dev_2.1.1-4_amd64
etc. my programs failed to compile because the compiler and linker
(using mpicc and mpifort provided by libopenmpi-dev)
could not locate MPI libraries. I found that several symlinks in
/usr/lib/x86_64-linx-gnu were dead links:
libmca_common_sm.so.20
libmpi_mpifh.so.20
libopen-pal.so.20
libopen-rte.so.20

By following the example of working links, I was able to manually
set up the needed links pointing to /usr/lib/x86_64-linux-gnu/openmpi/lib/
and then link lib*.so.20 to those links. The commands (as root) were:

ln -s openmpi/lib/libopen-pal.so.20.10.1 /usr/lib/x86_64-linux-gnu/libopen-pal.so.20.10.1
ln -s libopen-pal.so.20.10.1 /usr/lib/x86_64-linux-gnu/libopen-pal.so.20
ln -s openmpi/lib/libopen-rte.so.20.10.1 /usr/lib/x86_64-linux-gnu/libopen-rte.so.20.10.1
ln -s libopen-rte.so.20.10.1 /usr/lib/x86_64-linux-gnu/libopen-rte.so.20
ln -s openmpi/lib/libmca_common_sm.so.20.10.1 /usr/lib/x86_64-linux-gnu/libmca_common_sm.so.20.10.1
ln -s libmca_common_sm.so.20.10.1 /usr/lib/x86_64-linux-gnu/libmca_common_sm.so.20
ln -s openmpi/lib/libmpi_mpifh.so.20.11.0 /usr/lib/x86_64-linux-gnu/libmpi_mpifh.so.20.11.0
ln -s libmpi_mpifh.so.20.11.0 /usr/lib/x86_64-linux-gnu/libmpi_mpifh.so.20

After making those changes, my MPI programs compile, link, and execute
normally.
