#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
  clang 7                         |
----------------------------------+----------------------------------------
 {{{
 Operating system:Mac OS X 10.11.6
 Xcode version: 7.3.1

 Problem: The Terminal command

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

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

 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:

 libtool: compile:  /usr/bin/clang -DHAVE_CONFIG_H -I. -I../../../..
 -I/opt/local/include -L/opt/local/lib -I../../../../gst-libs -I

 -c gstglcontext_cocoa.m  -fno-common -DPIC -o .libs/libgstgl_cocoa_la-
 gstglcontext_cocoa.o

 executed in the folder

 `/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_gnome_gstreamer1
 -gst-plugins-bad/gstreamer1-gst-plugins-bad/work/gst-plugins-
 bad-1.12.0-i386/gst-libs/gst/gl/cocoa'

 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' >
 #else
         < original statement >
 #endif

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

Comment (by ryandesign):

 Sounds like a problem that is unlikely to be specific to MacPorts, so it
 should be reported to the developers of this software.
