qt compile mac os undefined symbols AVFMediaPlayerService AVFVideoRendererControl

问题

Im trying to compile Qt 5.9.x on my Mac OS High Sierra computer.

I configure with the following options:

./configure --prefix=/Users/myuserid/opt/qt593 \
    -opensource  \
    -release -gui -widgets -no-opengl -confirm-license \
    -shared -no-dbus -nomake examples

After configuring I compile and after a while it stops with the following undefined symbols:

Undefined symbols for architecture x86_64:
  "AVFVideoRendererControl::staticMetaObject", referenced from:
      AVFMediaPlayerService::releaseControl(QMediaControl*) in avfmediaplayerservice.o
  "AVFVideoRendererControl::AVFVideoRendererControl(QObject*)", referenced from:
      AVFMediaPlayerService::requestControl(char const*) in avfmediaplayerservice.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[5]: *** [../../../../plugins/mediaservice/libqavfmediaplayer.dylib] Error 1
make[4]: *** [sub-mediaplayer-make_first] Error 2
make[3]: *** [sub-avfoundation-make_first] Error 2
make[2]: *** [sub-plugins-make_first] Error 2
make[1]: *** [sub-src-make_first] Error 2
make: *** [module-qtmultimedia-make_first] Error 2

How do I fix or get past this error? I haven't seen an AVMediaPlayer package to download for Mac OS? I really don't need it anyhow since Im not planning on doing any Sound or Video?

Anyone see this error and know how to fix it? Thanks

I'm currently compiling Qt 5.9.3 on osx. I get the same error when I use the '--no-opengl' switch, without it, the compilation is successful. I don't know if this is an option for you, though.
