Source: mpich
Version: 3.2-6
Severity: important
A symlink /usr/lib/libmpich.so.12 is created only depending on what order the
packages libmpich12 and libmpich-dev are installed in, apparently requiring
libmpich-dev to be unpacked before libmpich12 is configured. In a clean
chroot:
# dpkg --purge libmpich12 libmpich-dev
# apt-get install libmpich12
# apt-get install libmpich-dev
# ls -l /usr/lib/libmpich.so.12
ls: cannot access '/usr/lib/libmpich.so.12': No such file or directory
# dpkg --purge libmpich12 libmpich-dev
# apt-get install libmpich12 libmpich-dev
# ls -l /usr/lib/libmpich.so.12
lrwxrwxrwx 1 root root 9 Jul 16 05:12 /usr/lib/libmpich.so.12 -> libmpi.so
Because libmpi.so is part of the update-alternatives group with OpenMPI,
problems can result when they're both installed:
# readlink -f /usr/lib/libmpich.so.12
/usr/lib/x86_64-linux-gnu/libmpich.so.12.1.0
# apt-get install libopenmpi-dev
# readlink -f /usr/lib/libmpich.so.12
/usr/lib/openmpi/lib/libmpi.so.12.0.3
This hits any package that builds against both MPI variants, causing failures
in dpkg-shlibdeps when it can't find MPICH symbols in /usr/lib/libmpich.so.12:
it's responsible for a FTBFS bug on yorick [1] and a whole bunch of build
failures on gromacs in experimental [2]. I don't know why it's suddenly a
problem now, but the buildds now seem to be installing the packages in the
order that triggers this problem more often than not.
