It's not good enough to put it in the source code which uses the library : {-# LANGUAGE ForeignFunctionInterface #-} what I don't understand is why the hsc processing and/or cabal build doesn't automagically handle this. maybe a ghc version thing ? I'm using 6.12.1. the binding-DSL examples do NOT use the above PRAGMA anywhere in the code.
