I'm developing an application using qt5.11 on Raspberry Pi 3. My code works on my laptop with ubuntu 18.xx. When I put my code on the RPi, I can compile it with the Makefile (make -j2) but when I want to launch my program I get the following message:
16:02:44: Starting /home/pi/build-VideoProcessor-Desktop-Debug/VideoProcessor... **libEGL warning: DRI2: failed to authenticate** **qt5ct: using qt5ct plugin** (VideoProcessor:985): GLib-GObject-WARNING **: 16:02:55.208: cannot register existing type 'GtkWidget' (VideoProcessor:985): GLib-GObject-CRITICAL **: 16:02:55.208: g_type_add_interface_static: assertion 'G_TYPE_IS_INSTANTIATABLE (instance_type)' failed (VideoProcessor:985): GLib-GObject-WARNING **: 16:02:55.208: cannot register existing type 'GtkBuildable' (VideoProcessor:985): GLib-GObject-CRITICAL **: 16:02:55.208: g_type_interface_add_prerequisite: assertion 'G_TYPE_IS_INTERFACE (interface_type)' failed (VideoProcessor:985): GLib-CRITICAL **: 16:02:55.208: g_once_init_leave: assertion 'result != 0' failed (VideoProcessor:985): GLib-GObject-CRITICAL **: 16:02:55.208: g_type_add_interface_static: assertion 'G_TYPE_IS_INSTANTIATABLE (instance_type)' failed (VideoProcessor:985): GLib-GObject-CRITICAL **: 16:02:55.208: g_type_register_static: assertion 'parent_type > 0' failed I don't understand what's going on with my RPi because my code works with my laptop.
Somebody could help me? Thanks.
