OpenBLAS detection on Windows (and Linux) wanted #144

Closed miroi closed 8 years ago

miroi commented 8 years ago

Hi,

currently, the CMake's FindBLAS package does not detect the OpenBLAS library, which is the only one working for MS Windows:

https://ci.appveyor.com/project/bast/autocmake/build/1.0.413#L298

The previous _mathlibs.cmake contained working OpenBLAS detection. Would it be possible to have the corresponding openblas.cmake macro ?

Also, we would need Linux CI service testing openblas library detection.

Is there a some flag for math-libs preference (like pick openblas instead of system_native blas or atlas blas) ? Is it possible to combine libraries (like --openblas --blas ) in case of missing routines ?

It is certainly possible and certainly the plan to have such a module. I don't understand the question with the preference since you then tell exactly what you want by the flags. And combining math libraries is tricky. From the Autocmake perspective this is no problem but the code has to then deal with multiple definitions.

Hi,

wrt combining libraries: for example, openblas does not contain the whole lapack. Therefore I would combine -openblas -lapack to supply missing lapack routines in openblas. Is it good approach ?

Also, how about the automatic detection of MKL (ESSL) libraries ?

I have created a forum to discuss things and will try to keep issues for real issues. Please see http://autocmake.readthedocs.org/en/latest/general/help.html
