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. -- *JSR * *"Montani Semper Liberi"*
