Hello,
trying to install latest FF++ master on CentOS Linux release 7.4.1708 (Core) with cc (GCC) 6.3.1 20170216 (Red Hat 6.3.1-3) foowing instructions here : https://github.com/FreeFem/FreeFem-sources

It seems to be a bug in htool, can you try using --enable_htool=no during the configuration process?

Hello, thanks for this quick answer. Meantime, as suggested the compilation output, i added “-fpermissive” to g++ flags in order to see if the whole compilation ends correctly. It works, also the make check is OK. Yes i know it’s dirty trick…
In fact I think after many checks that it seems more related to the version of MPICH2. We use a ScaleMP patched version:
mpich2-1.4-vSMP3.5.20_20150819.el5.x86_64.rpm as part of the software bundle for our cluster.
I’ve seen that these version of MPICH2 use a void* for the first argument:
/opt/ScaleMP/mpich2/1.4/include/mpi.h:int MPI_Reduce(void* , void*, int, MPI_Datatype, MPI_Op, int, MPI_Comm);
but the FF++ expect a const void* . So may be it’s related to the version of our MPICH2. As it’s part of the ScaleMP bundle we have to check with them how to get a newer version of MPICH2.
Thank you for your time
ps: So may be it could be interesting to check the version of MPICH2 during the config process, what do you think about ?
Nice day
JM

Can you share the rmp package of FreeFem on CentOS 7 or other version! Thank you very much!
