[petsc-users] compiling 3.2 on Windows

[Dominik Szczerba]

I think I know what the reason is. blas/lapack seems to be linked on
cygwin as a cygwin library while I need a native Windows library, like
I am doing with hypre. Is there a way to go here or do I need to (and
actually can) setup blas/lapack myself? Will it also happen with
parmetis? Note, parmetis and blas/lapack used to compile fine natively
some time ago.
