[petsc-users] Using "long int" variable in MatSetValues

[Evan Um]

Dear PETSC users,

Using C++, I tried to build a very large sparse matrix and had a problem
shown below. Indices of the matrix should be "long int" rather than "int"
but PETSC does not allow this. How could I dodge this problem? Thanks for
your comments.

Regards,
Evan
