Hi Ana, Thanks! I created https://github.com/pmodels/mpich/pull/3667 to kick off the CI systems... Jeff On Thu, Mar 14, 2019 at 12:02 PM Ana Guerrero López via discuss < [email protected]> wrote:

Hi,

The current check in MPICH forcing to use exactly the same GCC version to build MPICH and the user programs is too restrictive. I got bitten by this and seems to be a recurrent problem, for example, see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=807666

The check was added many years ago by a problem with GCC3, so I think it could be safely removed. Please see attached patch.

Cheers, Ana
