[petsc-users] compiling 3.2 on Windows

[Satish Balay]

What do you have for:

cd /cygdrive/c/pack/petsc-3.2-p5/win64-msvc-release/lib/ dumpbin
/SYMBOLS libf2clapack.lib |grep dgetrs

For some reason configure is able to find ddot in libf2cblas.lib - but
not dgetrs in libf2clapack.lib [when invoked this way with
--with-blas-lib etc..]. And I don't understand why..
