• Product: Gentoo Linux
• Status: RESOLVED DUPLICATE

[Description Petr Pisar 2016-06-05 11:53:18 UTC]

kde-plasma/kinfocenter-5.5.5 defaults to USE=opengl without X flag. This combination fails to build on linking kcm_opengl.so:

See <https://forums.gentoo.org/viewtopic-p-7892228.html> for the same issue.

I think the ebuild should enable X, if opengl is requested. (I have no idea about wayland).

The X USE flag is dropped from 5.6.x because of this.
