Hello Giuseppe Thank you for raising the mpi related issues. The failing to load msh3 seems to me to be a more general issue not related to the parallel solver in particular. For the rest of the problems I do not have an immediate answer. I plan to try to upload freefem++-3.23 to unstable shortly so I will have a look on these issues.
