[petsc-users] compiler related error (configuring Petsc)

[maitri ksh]

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?
