Linux: Compiling Xorg programs

Thanks, it helped a lot. This allowed me to compile system without problem.

But we found out that while X is running gstreamer ducati plugin doesn't work. After killing X I use it to play video via kmssink. It fails in initialization like here(I attached strace of that command):

gst-inspect-1.0 ducatijpegdec

...1

version             : The codec version string

                       flags: ../git/libdce_linux.c:70: dce_init ERROR: Failed OmapDrm_FD > 0 error val -7readable

                       String. Default: null

4137.strace.txt

Edit: It appears to work with a ugly hack of replacing drmopen by do { OmapDrm_FD = open("/dev/dri/card0", O_RDWR | O_CLOEXEC);} while (OmapDrm_FD < 0) ;
