yes it works fine with android drivers/libraries, but not with linux EGL version

We were checking the wrong extension here. The correct extension is: GL_OES_EGL_image: http://www.khronos.org/registry/gles/extensions/OES/OES_EGL_image.txt

Comment on attachment 643547 [details] [diff] [review] patch I'm ok with the ext change but NOT the ifdef stuff. conditional r+ on that being removed.

Oops, fixed and carried over r+.

Ok, that fix did not solve the problem. real problem in lookup function which never initialized in GL context and without that function we cannot load symbols on linux (don't know why it works on android)

Comment on attachment 644807 [details] [diff] [review] SetupLookup function before load GL symbols Review of attachment 644807 [details] [diff] [review]: ----------------------------------------------------------------- Interesting. Yes, this is indeed the case. We do this on WGL, GLX, and even OSMesa, but not EGL. GLLibraryLoader::LookupSymbol is designed to try to work even in the absence of mLookupFunction, but it's not as likely to.
