Subject: [PATCH 2/4] Do not try to initialize GL without libGL
|
||
|
|
||
|
_gdk_x11_screen_update_visuals_for_gl() will end up calling epoxys
|
||
|
GLX api which will exit() if libGL.so.1 is not present. We do not
|
||
|
want that to happen and we don't want every app to have to set
|
||
|
"GDK_GL=disabled" environment variable: so use #ifdef set based on
|
||
|
opengl distro feature.
|
||
|
|
||
|
Upstream is not interested in the fix as it is: Either epoxy should be
|
||
|
fixed (to not exit) or GTK+ possibly could do some additional probing
|
||
|
before calling epoxy APIs.
|
||
|
|
||
|
Upstream-Status: Denied
