>foreign import "fooble" fooble
> fooble :: PackedString -> Int -> IO Int
>
>type PackedString = ByteArray Int
With the code above I'm getting the following error:
-- Unacceptable argument type in foreign declaration: PackedString
-- When checking declaration:
-- foreign import _ccall "fooble" fooble :: PackedString -> Int -> IO Int
Is there any option that I must include when I launch ghc (I'm very new to
this compiler, as to Haskell)?
-- I'm trying with "ghc -c -fglasgow-exts test.hs"
Best regards,
Corneliu
