#54202: gstreamer1-gst-plugins-bad @1.12.0 : incompatible types casting
'dispatch_queue_t' to 'gpointer'
 Reporter:  herzog-bernd          |      Owner:
     Type:  defect                |     Status:  new
 Priority:  Normal                |  Milestone:
Component:  ports                 |    Version:  2.4.1
 Keywords:  bridget cast in       |       Port:  gstreamer1-gst-plugins-bad

 Problem: The Terminal command

         sudo port -svk install gstreamer1-gst-plugins-bad +universal

 emits the above error message. More precisely, the complete error messages

 gstglwindow_cocoa.m:131:28: error: incompatible types casting
 'dispatch_queue_t' (aka 'struct dispatch_queue_s *') to 'gpointer' (aka
 'void *') with a __bridge_retained cast
   window->priv->gl_queue = (__bridge_retained gpointer)
                            ^                  ~~~~~~~~
 gstglwindow_cocoa.m:404:31: error: incompatible types casting 'gpointer'
 (aka 'void *') to 'dispatch_queue_t' (aka 'struct dispatch_queue_s *')
 with a __bridge cast
   dispatch_queue_t gl_queue = (__bridge dispatch_queue_t)priv->gl_queue;
                               ^         ~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~

 They come from the compiler call:

 The project builds without error, if one replaces the bridged casts by
 usual casts. One could replace
 the two problematic statements with conditionals

 #if defined(__llvm__) && __clang_major__ == 7
     < the statement without any '__bridge_retained' or '__bridge resp' >
         < original statement >

 I'm not sure whether this fixes the problem: it should be decided by
 someone who really knows
 what's going on.
