osx - Unable to link OpenGL compatibility profile (EXT symbols not recognized) -


i decided use glew handling extensions instead of requesting core profile , having migrate code.

i add support fbo's through ext profile first step.

the problem gcc not link code (osx 10.10), not recognize gl*ext() functions. instance, glbindframebufferext()

flags undefined symbol. (glbindframebuffer() unrecognized...)

i link against glew , have tried using glext or glfw compatibility profile, nothing works! missing library? how tell gcc use right gl profile? obliged migrate core profile?

in macos x glew not doing lot, because there not lot of opengl extensions on macos x , due way opengl integrated in macos x functions of opengl version supported available framework available

… or not, if you're using extension function that's not supported macos x's opengl implementation.

macos x weird duckling in opengl family: opengl used @ low level in os's core graphics routines, opengl supported os. it's built deep os hardly can updated without updating whole os.

solution: don't use extension. fbos have been introduced opengl-3.3 you've create 3.3 core profile context , can use functions (without …ext) directly.
