[mpich-discuss] Needs information

[Dave Goodell]

In general, we recommend compiling with "mpicc" (and friends) rather than attempting to get the compiler flags correct yourself.  However, if you really don't want to do that, then look at the output of "mpicc -show" (or the equivalent command for your language, cxx maybe?).  It looks to me like you're missing a "-L" for the MPICH2 lib directory.
