Hello, I built PETSc with -with-cxx=0 in order to get around a likely Intel C++ compiler bug. However, the MPICH that also gets built by PETSc then picks up the wrong C++ compiler; mpicxx -show indicates that it is using G++, while mpicc is correctly using icc.
Is there a way to get PETSc to pass the correct C++ compiler for the MPICH build when using -with-cxx=0? I need to compile parts of my own program with mpicxx/icpc.
