Thanks for pointing this out. I do notice with grep that gst_plugin_app_register is located in the gst_build/lib/gstreamer-1.0/libgstapp.a. So I've included: LIBS += -L$$PWD/gst_build/lib -l:libgstapp-1.0.a LIBS += -L$$PWD/gst_build/lib/gstreamer-1.0 -l:libgstapp.a But this still does not resolve the undefined reference error... > -- > Sebastian Dröge, Centricular Ltd · http://www.centricular.com > > _______________________________________________ > gstreamer-embedded mailing list > gstreamer-embedded@xxxxxxxxxxxxxxxxxxxxx > http://lists.freedesktop.org/mailman/listinfo/gstreamer-embedded > _______________________________________________ gstreamer-embedded mailing list gstreamer-embedded@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/gstreamer-embedded
