Hi
However, I also want to develop Hoogle using WinHugs on Windows on a computer without a C compiler, and it seems that the generated Paths_Hoogle module requires FFI on Windows? Is there any way round this, or am I just out of luck in using Cabal's path feature in this situation?
Perhaps it could call things from the System.Win32 lib instead of doing the FFI directly.
Could you investigate what external functions we need exactly and if they're exported from System.Win32.
foreign import stdcall unsafe "windows.h GetModuleFileNameA" getModuleFileName :: Ptr () -> CString -> Int -> IO Int32
That's the only one. Wouldn't it make more sense to put this FFI call in Cabal (which is always there, and always required) instead of Win32, which isn't an existing dependancy?
Well I guess that's just the issue. Cabal also isn't an existing dependency. It'd be pretty bad to make every library & program depend on Cabal. Perhaps it's just as bad to make it depend on Win32, but I think it's probably less bad. Or it could go in base or we could leave it as is as an FFI import. Duncan
