Hi I would like to install xmonad 0.9.2 (which worked fine for me) on my Ubuntu 12.04 system (GHC 7.4.1). Following the instructions on README, xmonad-0.9.2 compiles fine but xmonad-contrib-0.9.2 fails at the build stage: [101 of 180] Compiling XMonad.Layout.MouseResizableTile ( XMonad/Layout/MouseResizableTile.hs, dist/build/XMonad/Layout/MouseResizableTile.o ) XMonad/Layout/MouseResizableTile.hs:182:17: Could not deduce (Eq t) arising from the literal `0' from the context (Num t) bound by the type signature for replaceAtPos :: Num t => [Rational] -> t -> Rational -> [Rational] at XMonad/Layout/MouseResizableTile.hs:(182,1)-(185,61) Possible fix: add (Eq t) to the context of the type signature for replaceAtPos :: Num t => [Rational] -> t -> Rational -> [Rational] In the pattern: 0 In an equation for `replaceAtPos': replaceAtPos [] 0 x' = [x'] cabal: Error: some packages failed to install: xmonad-contrib-0.9.2 failed during the building phase. The exception was: ExitFailure 1 Is there a way to get this to build on my system? thank you for any help ~l
