Even so the "numeric_bindings" are also tested with mkl, I have to admit that I tested the cblas interface only with atlas, not with mkl. So I didn't notice that you are forced to include both the headers from the "numeric_bindings" and "mkl_cblas.h" in the same source file. However, fixing this is not high on my priority list.

Hi Tomas

My fix is:

#ifndef BOOST_NUMERIC_BINDINGS_CBLAS_INC_H
#define BOOST_NUMERIC_BINDINGS_CBLAS_INC_H

extern "C" {

#ifdef BOOST_NUMERIC_BINDINGS_MKL
#include <mkl_cblas.h>
#include <mkl_service.h>
#undef P4 // mkl_types.h defines P4 macro which breaks MPL
#else
#include <cblas.h>
#endif

}

#endif
