John, Configuring with --enable-shared or --enable-shared=yes should have worked for this. Can you send your config.log so we can inspect and see what went wrong? Ken ----- Original Message -----

Greetings to all,

I have successfully built mpich-3.0.4 to work with some applications that require parallel support. But, I face a problem that I haven't been able to solve:

I need to setup boost libraries (from boost.org ) in my system and an error has popped up. The error indicates that, during the attempt to setup boost, the library libmpich.a cannot be used when making shared objects. It is my understanding that I should use a library called libmpich.so (or something similar, that allows the creation of shared objects), however such library is not created when I build mpich-3.0.4 .

Can anybody indicate to me whether I don't get the libmpich.so (or similar) because I'm missing something during the building of mpich-3.0.4 or because it's simply not created and I need to find another flavor of mpi for this? I appreciate any inputs.

Some extra info: - system: Ubuntu 12.04 (64-bit) - compilers used: GNU, including gcc, g++, cc, c++, cpp, f95, and gfortran - libraries built in /usr/local/lib/: libmpich.a, libmpich.la , libmpichcxx.a, libmpichcxx.la , libmpichf90.a, libmpichf90.la - attempts to run ./configure script with options: <none> and --enable-shared=yes. Both produce the same libraries mentioned above and not the desired libmpich.so (or similar)

Thanks a lot and best regards.
