Yes, using -i to give paths to installed packages does not work - you really have to tell ghc about the corresponding package.conf file, using -package-conf file. See also http://www.haskell.org/ghc/docs/latest/html/users_guide/packages.html#package-databases >> > catamorphism.example.hs:19:0: >> > Bad interface file: >> /root/.cabal/lib/category-extras-0.53.5/ghc-6.8.2/Control/Functor/Fix.hi >> > Something is amiss; requested module main:Control.Functor.Fix >> differs from name found in the interface file >> category-extras-0.53.5:Control.Functor.Fix >> > make: *** [all] Error 1 The problem is that all modules found by -i are expected to be in the current package - which is 'main' by default. (Build tools like Cabal specify a different package name for libraries; for example the Control.Functor.Fix is in the 'category-extras-0.53.5' package here.) > So, I've got to figure how to tell cabal install to install in right > place :( Have you tried 'cabal install --global'? To make it stick, put 'user-install: False' in root's .cabal/config file.
