[Haskell-cafe] GLFW Textures (bloxorz)

strangely I don't get this behavior. I'm also running GHC 6.10.4 on
Linux, Are you sure that your system GL driver handles double
buffering correctly?

BTW, "cabal install bloxorz" fails to compile due to some type
mismatch between GLfloat and Float. But once this is fixed, everything
compiles and runs smoothly.

One thing you might look into though, is to get glfw-2.6 C library
from http://glfw.sourceforge.net/, and see if running its sample
programs produces correct result. If they do, you can install the
dynamically linked glfw C library system wide, and re-install GLFW
haskell library using "cabal install GLFW --flags=dynamic". This will
tell GLFW to dynamically link with system glfw.so instead of compiling
a static version on its own.
