$ pkg-config --cflags libdrm -I/usr/include/drm -I/usr/include/libdrm Because of the first one trying to include a directory that does not exists everything that uses pkg-config to find cflags (on my system at least every gtk+ application) gets warnings like pulseaudio: cc1: warning: /usr/include/drm: No such file or directory This gives unecessary big and hard parsed build logs, and is just messy. The expected is that "pkg-config --cflags libdrm" should just include the directory libdrm has installed its include files to.
Confirmed. However, this seems to be fixed in 2.4.21; and as it is a minor issue, I think we'll simply wait till 2.4.21 goes stable.
Closing fixed, we'll start working on the stabilization of xorg-server 1.9 soon. Thanks
