Dear Peng, This part of the installation documentation <http://dealii.org/8.5.0/users/cmake.html#compiler> suggests that you can explicitly indicate which MPI compilers to use with the following flags passed to CMake:
cmake -DDEAL_II_WITH_MPI:BOOL=ON -DCMAKE_C_COMPILER="<full/path/to/mpicc>" > -DCMAKE_CXX_COMPILER="<full/path/to/mpicxx>" -DCMAKE_Fortran_COMPILER=" > <full/path/to/mpif90>" <...> I would suggest in your case to pass the full paths to the MPI executables since deal.II couldn't pick them up in the first place. Presumably the means that the binaries are located at /usr/local/bin/<mpicc/mpicxx/mpif90> on your machine. Does this help you solve the problem?
