Hi, When trying to emerge several apps which use libGL, (including mythtv, gtkglarea, smpeg) I recieve unknown reference errors when they are linked. It looks as though some functions which used to be available through libGL are now in libGLcore? If I modify the respective ebuilds to link against libGL and libGlcore they compile fine.

If I modify the setting.pro file for mythtv adding "-lGLcore" to the opengl EXTRALIBS variable it compiles.

I had an old 1.0.6xxx version of the GL libs that I had installed last year using Nvidias installer. running "nvidia-installer --uninstall" followed by a "opengl-update nvidia" fixes it. Oooops. Sorry.
