pdfpc quartz variant not working

[onnoeberhard (Onno Eberhard)]

I installed the +quartz variant of pdfpc (v4.5.0) (after installing gtk3 with +quartz). The installation works fine, but when I try to open pdfpc, I get the following error:

dyld[44980]: Symbol not found: _gdk_x11_display_get_type
  Referenced from: /opt/local/lib/libwebkit2gtk-4.0.37.44.4.dylib

Is webkit2-gtk also installed with +quartz?

[onnoeberhard (Onno Eberhard)]

Thanks! I installed webkit2-gtk with +quartz. Now I can open the application, but I get constant error windows popping up saying 'WebKitWebProcess quit unexpectedly'.

When I try to use the 'video playback' feature of pdfpc, I also get the following error:

(pdfpc:24847): GStreamer-WARNING **: 10:48:34.032: Failed to load plugin '/opt/local/lib/gstreamer-1.0/libgstgtk.so': dlopen(/opt/local/lib/gstreamer-1.0/libgstgtk.so, 0x0002): Symbol not found: _gdk_x11_display_get_type
  Referenced from: /opt/local/lib/gstreamer-1.0/libgstgtk.so
  Expected in: /opt/local/lib/libgdk-3.0.dylib

Could it be that there is still something installed with x11 instead of quartz which shouldn't be?

Yes; clearly /opt/local/lib/gstreamer-1.0/libgstgtk.so is. You can use port provides to find out what port installed that file and rebuild that port. However, there may be even more files than that.

This is why we suggest that you decide whether you want +x11 or +quartz before you install any ports. If you change your mind, it's safest to uninstall all ports, then make the change (e.g. in variants.conf), then reinstall the ports you want.

I also experience this behavior with +quartz, and the "notes" screen does not show (it is black). I am not trying to use video. That is likely a separate issue.

I just discovered that my black-screen issue on my non-presentation screen may have been caused because I had the option "Displays have separate spaces" disabled. I have since uninstalled pdfpc (and its many dependencies), and so I am not able to verify right now. Leaving this note in case it helps someone else.
