Re: [Haskell-cafe] help with glfw seg-fault

Ah, yeah, that blog post I linked is using the "gl" package rather than the "OpenGL"/"OpenGLRaw" packages, so some of the names of things are a bit different. Glad you got it sorted in the end! 2015-05-29 13:32 GMT+09:00 :

Hi Brian,

Have you checked for / output any GL errors that happen before you call swapBuffers? I have a function printErrors (as defined here http://dpwright.com/posts/2015/03/25/the-haskell-gl-package/#error-handling-... ) which I scatter around when things go wrong to try and find the root cause...

bug report!

m@(~(Just w)) <- createWindow 400 400 "Title" Nothing Nothing when (isNothing m) (error "Couldn't create window!")

GLFW.makeContextCurrent m ^^^^^^^^^^^^^^^^^^^^^^^^^

then no seg-faults.
