I guess we aren't talking about the same thing, but I've got to tell
you... I'm not surprised. The landscape of BLAS is incredibly
frustrating and oftentimes I can't make head or tail of instructions.
I was under the impression that using the Fortran libraries on Windows
is a major pain because of the unavailability of Fortran compilers for
Windows that are free and interoperate with Visual Studio well. As a
result, the solution is to use a C implementation of BLAS such as
gotoblas, which I compiled to a .lib. Now I just want to be able to use
that library with ublas. I thought that was accomplished by defining the
CLAPACK variable and then using the headers clapack.h and f2c.h which
are provided here
If you have the patience for it, I would appreciate it if you could
explain to me what ATLAS and LAPACK really are in relation to gotoblas
because now I'm completely confused.
