[Debian-astro-maintainers] Bug#1077267: gyoto FTBFS when MPICH is the default implementation because it lacks mpic++.mpich

[Thibaut Paumard]

Source: gyoto
Severity: serious
Tags: ftbfs
Justification: fails to build from source (but built successfully in the past)
X-Debbugs-Cc: thibaut at debian.org, Adrian Bunk <bunk at debian.org>

See #1077247: gyoto does FTBFS on 32-bit, due to mpich being used there.

This is due to the following code in debian/rules:
  # Make sure we build with the right MPI implementation
  include /usr/share/mpi-default-dev/debian_defaults
  MPICXX := /usr/bin/mpic++.$(ARCH_DEFAULT_MPI_IMPL)
  export MPICXX

I'm trying to fix it for gyoto by replacing mpic++.$() with mpicxx.$() there.
This should fix the issure for gyoto but I believe mpich should also provide
mpic++.mpich.

Cheers.
