Hi there,

A quick update regarding this WebKitGTK+ build failure...

It turns out that Buildroot it already doing the correct thing, and it's
passing “-DENABLE_OPENGL=OFF” when there is only an EGL provider but no
GL/GLES provider. As soon as I have a fix for the WebKit CMake files I can
send a patch to add it to Buildroot. In the meantime I am afraid that trying
to build WebKitGTK+ when the target only has EGL but no GL/GLES will be
broken — this is not expected to affect real-world uses, though; I imagine
whenever EGL is chosen there will be also GL/GLES as well.

I have also posted a set of two patches to get WebKitGTK+ updated to 2.18.6;
note that this build issue is still present in that new release.

Cheers,
