Comment 3 for bug 1215374

Hi Nautilus. -eglfs is not defined, but it's enabled by default if autodetected.

However it does not get enabled on x86, and defining it explicitly yields an error (see https://launchpadlibrarian.net/156301005/buildlog_ubuntu-trusty-amd64.qtbase-opensource-src_5.2.0~beta1%2Bdfsg-0ubuntu1~trusty1~test1_FAILEDTOBUILD.txt.gz) even though libegl1-mesa-dev is installed.

I guess it's because on x86 -opengl desktop is defined and on armhf -opengl es2. Technically using desktop OpenGL shouldn't necessarily disable EGL support, but maybe it does in Qt? So the question then becomes whether the ES2 subset of OpenGL should be used also on the desktop. The difference is general is probably not that huge, but I'm not aware of all the possible consequences.
