It doesn't look like it made it into the 1.4.1 release. Also, it's not just /usr/include that is a problem, but the fact that the wrappers are passing their paths before the user specified ones. Here's an example using mpich2 and openmpi with non-standard install paths. Mpich2 (Some output stripped as mpicc -compile_info prints everything): jbronder@mejis ~ $ which mpicc /usr/lib64/mpi/mpi-mpich2/usr/bin/mpicc jbronder@mejis ~ $ mpicc -compile_info -I/bleh x86_64-pc-linux-gnu-gcc -I/bleh -I/usr/lib64/mpi/mpi-mpich2/usr/include OpenMPI: jbronder@mejis ~ $ which mpicc /usr/lib64/mpi/mpi-openmpi/usr/bin/mpicc jbronder@mejis ~ $ mpicc -showme:compile -I/bleh -I/usr/lib64/mpi/mpi-openmpi/usr/include/openmpi -pthread -I/bleh Thanks, -- Justin Bronder
