CBLAS is kind of tricky to get working when it doesn't come bundled
with a BLAS implementation, so I wrote a little Fortran FFI and
updated math.blas to build off of it. It looks mostly like the C FFI.
You declare your Fortran functions using a bastardized C-ish syntax:
USE: alien.fortran
LIBRARY: blas
FUNCTION: REAL CDOTU
( INTEGER N, COMPLEX ALPHA, COMPLEX(*) X, INTEGER INCX,
COMPLEX(*) Y, INTEGER INCY ) ;
SUBROUTINE: SAXPY
( INTEGER N, REAL ALPHA, REAL(*) X, INTEGER INCX, REAL(*) Y,
INTEGER INCY ) ;
Right now it only supports the ABI used by g77/gfortran. Someday I'll
add support for the slightly different Intel Fortran and f2c ABIs,
which should cover the common cases used in commercial and free
software math software distributions.
