[Debichem-devel] Bug#924813: the error is in the libmpich-dev package

[Paul Dreik]

Hi,
It bugs out on the following file
/usr/include/x86_64-linux-gnu/mpich/mpicxx.h which is supplied by the
libmpich-dev package.

// Check for incompatible GCC versions

// GCC (specifically) g++ changed the calling convention

// between 3.2.3 and 3.4.3 (!!)  Normally such changes

// should only occur at major releases (e.g., version 3 to 4)

#ifdef __GNUC__
# if __GNUC__ >= 8
#  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



I believe this bug should be moved to that package instead. Is the error
perhaps because gcc was bumped to 8.3? I wonder if it's still relevant,
gcc 3.4.3 was released around 2004(?) or so.

Commenting out the line in the above file gets bagel to build again.
