Can't really see anything obviously bogus about the following:
% cat Foo.chs module Foo where
#include "foo.h"
fooOne i = {# call foo1 #} i
I solved my problem, but thought I'd send a mail to the list for anyone who's struggling as much as me (if that's even possible).
The problem was that GHC requires a commandline argument telling it to deal with FFI. Including the following in Foo.chs resulted in successful compilation:
{-# OPTIONS_GHC -fffi #-}
Or the simpler way is to include in your .cabal file: extensions: ForeignFunctionInterface That then applies to every module in the lib and has the advantage of being portable between compilers. Duncan
