I configured with the following command:

./configure --prefix=/home/ancborin/mpich2-install --enable-shared --enable-static --enable-wrapper-rpath

I did not find the directive for compiling for 32-bit.

I have the libmpich.so file in the directory /home/ancborin/mpich2-install/lib/, which is included in the LD_LIBRARY_PATH.

To run in parallel, I do: mpirun -np 2 firefly8.mpich2.ex -i EXAM09.INP -ex /home/ancborin/ff8_rc40_linux -o exam09.out -f

The problem, now, is: firefly8.mpich2.ex: error while loading shared libraries: libmpich.so: wrong ELF class: ELFCLASS64

Maybe, it has to do with the 32-bit version you have mentioned.

Any suggestion?

Best,
Antonio
