xmonad won't start: Irrefutable pattern failed for pattern (Data.Maybe.Just nbc_)

GoogleCodeExporter commented 8 years ago

What steps will reproduce the problem?
1. last line of ~/.xinitrc:
exec /Users/franco/.cabal/bin/xmonad

What is the expected output? What do you see instead?
I expect to have xmonad launch but i get this error in console

11/13/09 2:36:51 PM org.x.startx[7572]  xmonad-i386-darwin: 
XMonad/Main.hsc:(82,14)-(84,41): Irrefutable pattern failed for pattern 
(Data.Maybe.Just nbc_)

What version of the product are you using? On what operating system?
xmonad 0.9 (installed via cabal)
ghc-version (6.10.4) installed via the package
OSX 10.6.2 (Snow Leopard)

Are you using an xmonad.hs?  Please attach it and the output of "xmonad
--recompile".

import XMonad

main = xmonad defaultConfig

#no output

Please provide any additional information below.
on a mailing list i've seen hints that X cannot support the colors gray and red 
but i'm using a 
very stock snow leopard X11, only fullscreen is turned on

Changed state: Accepted
Added labels: Priority-Critical, Type-Defect

GoogleCodeExporter commented 8 years ago

What colors are safe for you?  Here's some Haskell to try in ghci, once you've
started X with some other window manager.

:m + Graphics.X11.Xlib XMonad.Operations
dpy <- openDisplay ""
mapM (initColor dpy) ["red", "gray", "blue", "black", "white", "#000000", 
"#ffffff"]

Feel free to put any other colors you think might work in that list on the third
line.  The ones that correspond to "Just" values (rather than "Nothing" values) 
are safe.

I think we are making progress!

From some testing on http://hpaste.org/fastcgi/hpaste.fcgi/view?id=12122#a12127 
, it
seems that XDefaultColormap is returning garbage (18022232529829921, rather 
than 32
on most systems).  Perhaps GHC is miscompiling the X11 bindings, or the user's 
libX11
is busted?

Unless some OS X testers can reproduce this, I can only assume this is a problem
specific to this user's set up.

I can reproduce this problem on a clean Snow Leopard installation.
Installed GHC 6.10.4, then the Haskell platform and then "cabal install xmonad".
This is the output of "cabal install xmonad"

I just ran a bunch of updates after installing snow leopard yesterday morning. 
After 
getting xmonad working initially it is now displaying this behavior

FYI, I get this error on 10.5.8, xmonad 0.9.1 from cabal; so it doesn't seem to 
be limited to Snow Leopard. I tried copying over the xmonad binary from 
~/.cabal/bin, but didn't seem to help.

I also get this exact same error with ghc 6.12.1, X11 1.5.0, xmonad 0.9.1 and 
snow leopard 10.6.4. I also tried to install via cabal.
