Re: [petsc-dev] Compiling C code with C compiler

What did you expect when you used --with-clanguage=C++ for your buid? Or were you misunderstanding what this options means wrt PETSc build?

I understand what it was trying to do but it is necessary for sieve (especially with certain mesh generators). Why does all of PETSc need to be compiled with C++ in order to use sieve is the real question? .c -> compiled with mpicc .cxx -> compiled with mpicxx Is there something else missing? (Perhaps linking?) Sean
