Bug 135289 – [GTK] Build depends on OpenGL ES

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Michael Catanzaro]

On Fedora I need mesa-libGLES-devel installed in order to build WebKitGTK+, but it's not listed in Tools/gtk/install-dependencies.

I'll add it to the list of Debian dependencies as well (which I did not test, but I'm pretty sure I have the right package).

How is the build failing?

Feel free to land this one.

If I remember correctly it's failing in Extensions3DOpenGLES.cpp.

Hrm. Odd. This should only be compiled if OpenGLES support is installed.

I think those are unconditionally build so I guess we need to add the proper guards

Why use(EGL) here? The context creation API shouldn't come into play here, as far as I can tell.

Sure, this change is not directly related to the failure, I just saw the egl include on top and decided to improve a bit the guarding of the file, but I can remove it.

Ah, I see now! I think it's okay to simply fail to build when you try to use OpenGLES without EGL. There aren't any platforms that support this configuration that I know of.
