• Status: RESOLVED DUPLICATE of bug 533704
• Product: Gentoo Linux

[Description Reto Gantenbein (ganto) 2015-01-03 16:57:27 UTC]

When I first tried to emerge webkit-gtk-2.6.4 with USE="-opengl" as I've configured it in /etc/portage/package.use for older webkit-gtk releases, the compilation failed with:

[...]

 }

If the "opengl" USE flag is added, the compilation successfully completes.

x11-libs/cairo-1.12.18 is installed with USE="X glib opengl openvg svg xcb xlib-xcb (-aqua) -debug (-directfb) (-drm) (-gallium) (-gles2) (-qt4) -static-libs -valgrind"

Reproducible: Always

Steps to Reproduce:
Compile webkit-gtk-2.6.4 with USE="egl geoloc gstreamer introspection jit libsecret spell webgl -coverage -debug -doc -opengl" emerge =net-libs/webkit-gtk-2.6.4
Actual Results:  
Compilation failed with the error mentioned above.

Expected Results:  
Compilation works or hint about invalid USE flag configuration.
