[petsc-users] Fortran: undefined reference to petscsfdistributesection

[Danyang Su]

Hi Matt,

Thanks.

BTW: DmPlexGetVertexNumbering now can work using the latest develop 
version. But the index is not in natural ordering when DMSetUseNatural 
is called. That's why I want to use PetscSFDistributeSection to check if 
I miss anything in the code.

Regards,

Danyang
