Can you look at that and see if we can either revert the broken develop change, or fix it so it’s still buildable with gcc-4.7?
Unintentional, and weird, the change were already on develop, was just a resync to make them unconflictig with master.

Work fine with 4.4.7 and intel mpi 5.0.3.
Can you point me to the error messages ?

They were all green, but perhaps I’m not patient enough and tests need to cycle again. Look at the Sandia-gcc-4.7.2, Sandia-gcc-4.7.2-c++11, and Sandia-clang-3.8, all available from this link.

Thanks for looking into this Alain.

There is an issue specific to the 2 cartesian test which is probably https://github.com/boostorg/mpi/pull/47 waiting for merge (I'll check and merge if relevant). These are the ones failing with clang3.8 and warning with g++5.4.0/no c++11. I'll check with 4.4.7/no11.
Checked with 4.3 to be safe. I merged 47, those should be ok.

Looks like different issues now:
