[Haskell-cafe] What's wrong with these foreign calls?

[Андрей Янкин]

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
