ghc-cvs-snapshot with wxHaskell

[Georg Martius]

Hi again,

Fuck! The problem is different indeed!
As Patrick pointed out earlier, the problem with the import-paths is the -M run, not the normal compilation run.
> /usr/bin/ghc -M wxcore/src/Graphics/UI/WXCore/WxcClassTypes.hs  \
>   -iout/wxcore/imports -Iwxc/include
works fine with ghc-6.2, but ghc-6.4:
> Could not find module `Graphics.UI.WXCore.WxcObject'
Therefore Patrick suggested to include -iwxcore/src/
However it should not be necessary for ghc, but I see why it needs it to produce the spurious line :-)
  Simon?

Another bug in ghc!
> /usr/bin/ghc -M wxcore/src/Graphics/UI/WXCore/WxcClassTypes.hs  \
>   -iout/wxcore/imports -Iwxc/include -iwxcore/src \
>   -odir out/wxcore/imports/Graphics/UI/WXCore/
produces (among others):
> out/wxcore/imports/Graphics/UI/WXCore//Graphics/UI/WXCore/WxcClassTypes.o : \	wxcore/src/Graphics/UI/WXCore/WxcClassTypes.hs
where you see that the -odir is not handled correctly.

Now I see the reason why I added the source directories to the import search-path in general. The current appoach for the depfiles (until the -odir thing is fixed):
  - include -isourcepath and NO -odir
  - use grep to get rid of the spurious dependency lines
  - use the old approach for renaming
(patch attached)

Cheers,
	Georg
