you should select carefully what type of warnings to disable in this way. in my example i turned off warnings only for unused variables and parameters that in general should not pose any serious threat to your code (in fact i cannot imagine an example in which such approach would fail, do you have

you can specity to gcc that warnings coming from outside library should be ignored wrapping the include in a pragma // Tell the compiler to ignore specific kind of warnings: #pragma GCC diagnostic ignored "-Wunused-variable" #pragma GCC diagnostic ignored "-Wunused-parameter" #include // Restor

To avoid this... if you are not needing to compile any fortran then you can just use the MPI that comes with OSX (OpenMP). Just set CC, CXX, etc to mpicc, mpicxx etc for both PetsC and libMesh... and don't tell PetsC to download mpich. Note that we don't typically work this way. We usually dow
