Is it possible for you to use a newer version GNU compilers?
If not - your alternative is to build PETSc with --with-cxx=0 option
But then - you can't use --download-superlu_dist or any pkgs that need c++ [you could try building them separately though]

I am trying to compile petsc on a cluster ( x86_64-redhat-linux, ' *configure.log'* is attached herewith) . Initially I got an error related to 'C++11' flag, to troubleshoot this issue, I used 'CPPFLAGS' and 'CXXFLAGS' and could surpass the non-compliant error related to c++ compiler but now it gives me another error 'cannot find a C preprocessor'. How to fix this?
