Hi, I've some questions related to Cabal. The command "ghc-pkg list" reports two versions of Cabal : 1.2.4.0 and 1.4.0.2. How do I get rid of the first one ? Also, I try to build a Cabal package of my own but configuring it doen't work : $ runhaskell Setup.lhs configure Configuring ae-fast-0.1... Setup.lhs: At least the following dependencies are missing: GLUT -any, OpenGL -an I have the OpenGL and GLUT packages (doing :m + them in ghci works). I run the configure command in this directory : $ ls ae-fast.cabal Graphics LICENSE Setup.lhs $ cat ae-fast.cabal name: ae-fast version: 0.1 Cabal-Version: >= 1.2 synopsis: Miscellaneous stuffs to easily try new ideas description: Miscellaneous stuffs to easily try new ideas category: Graphics license: BSD3 license-file: LICENSE author: Vo Minh Thu maintainer: Vo Minh Thu build-type: Simple Library Build-Depends: base, OpenGL, GLUT Exposed-Modules: Graphics.AE.Fast.GLUT What's wrong ? Thank you, Thu
