Applications should never just link directly against either libmpi.so or libmpich.so or anything else. They should always use mpicc and friends. Linking directly to a library without using mpicc and friends will break when MPICH2's I/O library enables support for some third-party libraries such as PVFS, for example. It'll automatically add more library flags to mpicc and friends, but the symbols are not added into libmpich.so Note that this is not the case for MPICH2 alone, but for any MPI implementation. For example, Open MPI uses our MPI I/O library, so they have the same problem too. -- Pavan -- Pavan Balaji http://www.mcs.anl.gov/~balaji -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".
