[petsc-users] PETSc on GCC

[Simon Zhang]

To whom it may concern,

I'm trying to install PETSc on my computer and PETSc is compliant with GCC
but something keeps going wrong at the compilation step. It's returning the
following message.

PETSc requires c99 compiler! Configure could not determine compatible
compiler flag.

How can I fix this problem?

Thank you,
Simon Zhang
