            Bug ID: 781606
           Summary: testegl-testegl.o: undefined reference to symbol
                    'glUniformMatrix4fv'
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Mac OS
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-omx
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: minfrin at sharp.fm
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

gst-omx from git master fails to build on Raspbian Jesse with the following
error:

/usr/local/gcc-6.2.0/bin/ld: testegl-testegl.o: undefined reference to symbol
'glUniformMatrix4fv'
/opt/vc/lib/libGLESv2.so: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status

The symbols are provided on the RPi as follows:

pi at towerofpi9:/opt/vc$ find . -type f -name "*.so*" | xargs nm -o 2>/dev/null |
grep glUniformMatrix4fv
./lib/libGLESv2.so:0000f29c T glUniformMatrix4fv
./lib/libbrcmGLESv2.so:0000f2a4 T glUniformMatrix4fv

It appears that the gstreamer build is passing the libraries in the wrong
order, thus causing the breakage.

Not a clue what the right order is, alas.
