[Trilinos-Users] [EXTERNAL] trilinos in MSVC

Fri May 17 14:22:19 MDT 2013

Dear Brent,
Thank you for the elaboration. I didn't have any success with
CLAPACK_CMAKE so used the f2cblas and f2clapack libraries from the
previous installation of petsc. Interestingly they worked!
So, I made separate VC projects for f2cblas and f2clapack,
successfully compiled them. (The only issue was the missing quadruple
scalar definition in VC++). Now, everything is fine.

Thank you Chetan, your script helped me a lot.
Thank you Ross for your advise.

Yours,
Mohammad
