In the MPI/LAM world the issues of linking are often complex enough that helper scripts are needed to build packages. Common helper scripts in MPI are called mpicc, mpif77, mpiCC and such. When you configure a message passing program it can help if you configure the C compiler to be "mpicc" and not gcc. The helper script "mpicc" will correctly invoke the C compiler used to build the MPI libs and find all the libs as needed. Of interest one of the authors of LAM has begun pointing MPI programmers at Open MPI because LAM support is waining. Is there a chance that you have multiple MPI packages. Last I invoked LAM I had to use 'alternatives to get it right. alternatives [] (8) - maintain symbolic links determining default commands -- T o m M i t c h e l l Found me a new hat, now what? -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
