BTW: the above doesn't make sense. Its suprising that this install is working. You should either use the prebuild mpi you have: ./configure --with-cc=mpicc --with-cxx=mpic++ --with-fc=mpif90 --download-f-blas-lapack --download-hypre or build mpich with the native compilers: ./configure --with-cc=gcc --with-cxx=g++ --with-fc=gfortran --download-mpich --download-f-blas-lapack --download-hypre Satish
