Created attachment 427622 [details] Proposed fixed ebuild Emerging net-libs/webkit-gtk-2.10.7 with USE="-opengl -gles2" triggers the following configuration error: CMake Error at Source/cmake/OptionsGTK.cmake:306 (message): Either OpenGL or OpenGLES2 is needed for ENABLE_OPENGL. Call Stack (most recent call first): CMakeLists.txt:168 (include) -- Configuring incomplete, errors occurred! This is due to the ebuild not overriding the default ENABLE_OPENGL=ON when neither the opengl or the gles2 USE-flags are used. The attached ebuild does just that, it fixes the problem for me. Here is the diff to the current version: --- /usr/portage/net-libs/webkit-gtk/webkit-gtk-2.10.7.ebuild 2016-03-01 05:28:51.000000000 +0100 +++
