Package: libmpich-dev Version: 3.1-6 Severity: grave Justification: renders package unusable
/usr/include/mpich/mpicxx.h has a hardwired dependency on the gcc used to build mpich (gcc 5.2): #ifdef __GNUC__ # if __GNUC__ >= 5 # if __GNUC_MINOR__ > 2 && 2 == 2 # error 'Please use the same version of GCC and g++ for compiling MPICH and user MPI programs' # endif # endif #endif But the current gcc (on s390x) is 5.3. So an error is thrown when building client programs (cf. Bug#803477), making mpich mostly unusable on this architecture. libmpich-dev has a dependency on gcc. But because the version in mpicxx.h has been hardwired like this, I think that means libmpich-dev should have a versioned Depends: gcc (<=4:5.2), Conflicts: gcc (>4:5.2) In any case, mpich needs to be rebuilt, on s390x at least, to update the gcc dependency in mpicxx.h. -- System Information: Debian Release: stretch/sid APT prefers unstable APT policy: (500, 'unstable'), (1, 'experimental') Architecture: s390x
