Hello everybody,

I was trying to build xmonad and stumbled upon a problem. I have already installed X11-1.3.0 and X11-extras-0.4. It seems that they both expose a module 'Graphics.X11.Xlib.Extras'. As a result of this, while trying to build xmonad, I get: ---------------------------------------------------------------- santanu@sc214:~/Desktop/xmonad/xmonad-0.4$ runhaskell Setup.lhs build Preprocessing executables for xmonad-0.4... Building xmonad-0.4... XMonad.hs:38:7: Could not find module `Graphics.X11.Xlib.Extras': it was found in multiple packages: X11-extras-0.4 X11-1.3.0

santanu@sc214:~/Desktop/xmonad/xmonad-0.4$ ghc-pkg list /usr/lib/ghc-6.6/package.conf: Cabal-1.1.3, Cabal-1.1.6, X11-1.3.0, X11-extras-0.4, base-2.0, filepath-1.0, (ghc-6.6), haskell98-1.0, mtl-1.0, parsec-2.0, readline-1.0, regex-base-0.71, regex-compat-0.71, regex-posix-0.71, rts-1.0, stm-2.0, template-haskell-2.0, unix-1.0, unix-2.0 -----------------------------------------------------------------

How do I solve this problem? (I am completely new to haskell. So I apologize in advance if this is too trivial a question).

By the way, I also tried to unregister X11-1.3.0 and installed X1-1.2.3 (since it does not seem to expose the module in question) and tried again. But that did not work either.

Thanks in advance for your help.

Regards, Santanu Chatterjee

Yes, you've run across an inadvertant problem with the recent release of X11-1.3.0. To build xmonad 0.4, you should use only X11 1.2.3, and X11-extras. So you should unregister X11 1.3.0, install X11 1.2.3, and X11-extras, and then be sure to clean your xmonad build: runhaskell Setup.lhs clean before rebuliding, which should solve any remaining build problem. Spencer, perhaps we should do a point release of xmonad -- or just get 0.5 out sooner? -- Don
