You have to know how the Fortran compiler's API maps to a C API, but there are only two or three conventions around, which differ in trivial things like underscores added to subroutine names. Fortran 95 and later are a different story. Konrad. -- You received this message because you are subscribed to the Google Groups Racket Users group.

Julia is also speedy doing math. I wrapped a bit of Fortran recently: https://github.com/jkominek/lbfgsb/ I had to learn more about the Fortran ABI than I cared to, but it's doable. If you needed to do a lot of it, it would be worth creating something like ffi/fortran/unsafe with FFI types that map a bit more directly to Fortran's types, and wrapping _fun with something that know's about Fortran's quirks. -- Jay Kominek -- You received this message because you are subscribed to the Google Groups Racket Users group.
