[mcstas-users] openmpi compilation problem

[Emmanuel FARHI]

Hi Jean-Francois,

to my knowledge, this is just a warning. The tar.gz configure; make; 
make install should proceed OK still, and McStas should be able to find 
MPI if 'mpicc' and 'mpirun' commands are available at the prompt.

OpenMPI seems OK on recent systems. It was less reliable than MPICH 
until 2010-2011 (would stall for long simulations with e.g. ncount > 2e9).

Emmanuel.
