Re: undefined reference to `eglGetProcAddress'

I tried the latest build . Still having the same problem .
Is there a problem with my cogl build? Maybe?

It's very hard for me to tell you whether you have a problem with your setup, but have you tried building webkit-clutter without webgl support?

I tried with nm utility, libEgl.so has eglGetProcAddress with reference , but libwekit_clutter.so shows this with U flag.

and the function eglProcAddress inside the wekit is exported with KHRONOS_API , so it should've been exported, but its not?

Should i export it somehow?

Well, Cogl should be abstracting the GL* APIs, so you shouldn't have to care about that. We used to do some weird stuff in order to support WebGL and the snapshot you have may still have the problematic code.

As said before, try with a more recent snapshot (I would recommend latest master if you are going to ask for help upstream, to make easier for others to help you).

I tried compiling webkit snapshot webkit-clutter-1.11.2+20130129+5cf54f3,

having clutter 1.13.2 and mx-2.0,

have egl glx and opengl installed and recognized by webkit.

Disabled egl as backend option , so its installed with opengl and glx backend.

Though this should work, I don't know of anybody that is currently testing webkit-clutter with big GL (only with GLES2), so there may be bugs lingering. I would also recommend using a more recent version.

For debugging this kind of linker errors, I recommend reading this page and getting familiar with the tools mentioned:
