Comment:
I poked around on this a little and found that loadDynamic in
compiler\ghci\Linker.lhs doesn't try to append an extension because addDll
(from job rts\Linker.c) does that job. But if you don't add the extension
it isn't going to find the file.
{{{
#!hs
-- return Nothing == success, else Just error message from dlopen
loadDynamic :: [FilePath] -> FilePath -> IO (Maybe String)
loadDynamic paths rootname
= do { mb_dll <- findFile mk_dll_path paths
; case mb_dll of
Just dll -> loadDLL dll
Nothing -> loadDLL (mkSOName rootname) }
-- Tried all our known library paths, so let
-- dlopen() search its own builtin paths now.
where
mk_dll_path dir = dir </> mkSOName rootname
mkSOName :: FilePath -> FilePath
mkSOName root
| isDarwinTarget = ("lib" ++ root) <.> "dylib"
| isWindowsTarget = -- Win32 DLLs have no .dll extension here, because
-- addDLL tries both foo.dll and foo.drv
root
| otherwise = ("lib" ++ root) <.> "so"
}}}
