           Summary: conflicting types for ‘GLsync’
    Classification: Platform
           Product: GStreamer
           Version: git master

            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: ensonic at sonicpulse.de
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

Unlike in https://bugzilla.gnome.org/show_bug.cgi?id=777167 I am still with

here
 typedef struct __GLsync *GLsync;
                          ^~~~~~

Which means the check in gst-plugins-base/m4/gst-gl.m4 GLsync is not defined
and hence defines it. The configure check in base that fails is:

conftest.c: In function 'main':
conftest.c:105:21: error: expected expression before ')' token
 if (sizeof ((GLsync)))
                     ^

The last thing to note, is that those types are conditionally defined in the gl
headers.
