Simon??
This is because ghc -M works like --make, in that it traverses the module dependency graph. When multiple modules are being considered, the -ohi flag doesn't make much sense (which module does it apply to?). The right way is to use -hidir/-hisuf, which are honoured by -M and --make. Cheers, Simon

Okay that sounds reasonable. I was looking for an -odir equivalent for hi files anyway. (It was not that hard :-)). The problem with hierarchical libs remains. Example: ./out ./out/Foo ./src ./src/Foo ./src/Foo/Bar.hs
module Foo.Bar where import Foo.Bla ./src/Foo/Bla.hs module Foo.Bla
ghc -M -odir out/Foo/ -hidir out/Foo/ src/Foo/Bar.hs -isrc # DO NOT DELETE: Beginning of Haskell dependencies out/Foo//Foo/Bla.o : src/Foo/Bla.hs out/Foo//Foo/Bar.o : src/Foo/Bar.hs out/Foo//Foo/Bar.o : out/Foo//Foo/Bla.hi # DO NOT DELETE: End of Haskell dependencies
@Daan: why don't you use --make anyway? It would make obsolete so many problems IMO. Cheers, Georg -- ---- Georg Martius, Tel: (+49 34297) 89434 ---- ------- http://www.flexman.homeip.net ---------
