If you load this function in ghci, it behaves absolutely the same way.
How can I create OpenGL window in
GLFW-b in ghci?

Prelude> initWindow
Loading package array-0.4.0.0 ... linking ... done.
Loading package deepseq-1.3.0.0 ... linking ... done.
Loading package containers-0.4.2.1 ... linking ... done.
Loading package GLFW-b-0.1.0.2 ... linking ... done.
DefaultProfile
Version {versionBranch = [2,7,2], versionTags = []}
Version {versionBranch = [0,1944,1342031663], versionTags = []}
"Trying to open the window"
False

For me it seems like calls to GLFW are normal but when I use indirectly GL (through GLFW) I see a mess.
How could not they be connected properly?

Please, give me any hint...
I use Ubuntu 12.04 and The Glorious Glasgow Haskell Compilation System, version 7.4.1

Hi all!

I want to use GLFW-b ( http://hackage.haskell.org/packages/archive/GLFW-b/0.1.0.2/doc/html/Graphics-UI-GLFW.html ) and I wrote this:
  initWindow = do
    True <- GLFW.initialize
    print =<< GLFW.openGLProfile
    print =<< GLFW.getGlfwVersion
    print =<< GLFW.getGlVersion
    print "Trying to open the window"
    result <- GLFW.openWindow GLFW.defaultDisplayOptions
    print result

And got this:
  DefaultProfile
  Version {versionBranch = [2,7,2], versionTags = []}
  Version {versionBranch = [-1867951663,39789305,39789305], versionTags = []}
  "Trying to open the window"
  False

Why do I always get random numbers as GLVersion?
How can I detect incompatibility preventing me from opening a window?

Thanks in advance
