Re: [xmonad] xmonad: xmonad-extras 0.12 fails to build

Thanks for responding Brent. Not very good at haskell myself. Im looking at the XMonad.Actions.Volume and there i find: infixl 1 <* (<*) :: Monad m => m a -> m b -> m a pa <* pb = pa >>= \a -> pb >> return a I'm assuming this is what you were referring to for solution (1). I've been trying to play with it but i get mixed errors when building, how do i rename? Here is the code just in case im looking at it wrong: https://hackage.haskell.org/package/xmonad-extras-0.12/src/XMonad/Actions/Vo... I also plan to email the maintainer, but i would like to have this work for educational purposes. Thanks, Dave On Thu, Apr 9, 2015 at 10:04 AM, Brent Yorgey wrote:

It looks like XMonad.Actions.Volume defines an operator (<*), but as of base-4.8 an operator with that name has been added to the Prelude. The fix would be to either (1) rename the operator in XMonad.Actions.Volume, or (2) hide the operator from Prelude and tell everyone who wants to use XMonad.Actions.Volume.(<*) that they need to hide it from Prelude too.

xmonad-extras is not officially a part of the xmonad project; you should contact the maintainers listed at http://hackage.haskell.org/package/xmonad-extras .

This is my first time posting here so i hope im doing this right. Just updated ghc to 7.10.1 and had to rebuild xmonad, xmonad-contrib, and xmobar. I also use xmonad-extras but it failed during the build. I tried using cabal and also from source but both give same output:

$ cabal install xmonad-extras

I got to look at the log but it just has what i pasted above. System is Arch 3.19.2-1-ARCH

Any input is appreciated. Thanks dave _______________________________________________ xmonad mailing list xmonad@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/xmonad
