The correct thing to do here is specify the compilers to configure. ./config/configure.py --with-cc=gcc --with-fc=g77 --download-mpich=1 --download-f-blas-lapack=1 If you need to use PETSc from different compilers [or other variation in options] create multiple installs of PETSc with different values of PETSC_ARCH ./config/configure.py --with-cc=gcc PETSC_ARCH=linux-gcc make PETSC_ARCH=linux-gcc ./config/configure.py --with-cc=icc PETSC_ARCH=linux-icc make PETSC_ARCH=linux-icc etc..
