[petsc-users] Can not find the header file for OpenMPI

[Satish Balay]

You are misinterpreting  --with-mpi-include --with-mpi-lib options.

Any particular reason you want to use these options instead of mpi compilers?

$ mpicc -show
gcc -I/home/balay/soft/mpich-4.0.1/include -L/home/balay/soft/mpich-4.0.1/lib -Wl,-rpath -Wl,/home/balay/soft/mpich-4.0.1/lib -Wl,--enable-new-dtags -lmpi

gfortran -fallow-argument-mismatch -I/home/balay/soft/mpich-4.0.1/include -I/home/balay/soft/mpich-4.0.1/include -L/home/balay/soft/mpich-4.0.1/lib -lmpifort -Wl,-rpath -Wl,/home/balay/soft/mpich-4.0.1/lib -Wl,--enable-new-dtags -lmpi

i.e here I would use:

--with-cc=gcc --with-cxx=g++ --with-fc=gfortran --with-mpi-include=/home/balay/soft/mpich-4.0.1/include --with-mpi-lib="-L/home/balay/soft/mpich-4.0.1/lib -Wl,-rpath -Wl,/home/balay/soft/mpich-4.0.1/lib -lmpifort -lmpi"
