[petsc-users] petsc on windows

[Sam Guo]

Thanks for the quick response. Attached please find the configure.log
containing the configure error.

Regarding our dup, our wrapper does support it. In fact, everything works
fine on Linux. I suspect on windows, PETSc picks the system mpi.h somehow.
I am investigating it.

Thanks,
Sam
