Where is the mpi.h header? (I can't seem to build mpich myself.) You probably need to add that directory to CPPFLAGS with an -I argument. For example if it is in /opt/local/include, you need... export CPPFLAGS=-I/opt/local/include ...before you begin. Similarly, you probably need to say where the libraries are, e.g. with: export LDFLAGS=-L/opt/local/lib _______________________________________________ macports-users mailing list [email protected] http://lists.macosforge.org/mailman/listinfo.cgi/macports-users
