There’s this patch file…

package/qt5/qt5multimedia/0008-gsttools-videooverlay-Support-overriding-video-win-i.patch:+ QVideoWindowAbstractInterface *intf =
package/qt5/qt5multimedia/0008-gsttools-videooverlay-Support-overriding-video-win-i.patch:+ dynamic_cast<QVideoWindowAbstractInterface *>(window);
package/qt5/qt5multimedia/0011-gsttools-videowidget-Provide-widget-window-id-for-vi.patch:+class QGstreamerVideoWidget : public QWidget, public QVideoWindowAbstractInterface

which adds 'QVideoWindowAbstractInterface ’ to qgstreamervideooverlay.cpp in linux-sdk/buildroot/output/rockchip_rk3399/build/qt5multimedia-5.6.3/src/gsttools/ which causes this error

I’ve grepped for QVideoWindowAbstractInterface in the entire tree, and can only find the moidifed sources and the patch file.

Please do a repo sync first before building.
The Qt version in the up-to-date Buildroot is 5.9.4 , FYI.

Okay, assuming I didn’t, but did subsequently (and periodically) do repo sync after building? How do I fix it?

Repo diff shows 0 differences…

As I was writing that, I realized, maybe you mean ‘do it NOW’ so I did a sync and got some updates but it’s still failing in the same area.

This is biuldroot/packages/qt5/qtmultimedia
I guess last time I tried this was july 17 which is before this all started…

is there a stable tag point/checkpoint I can get back to?
In ‘repo branches’ there are no branches…
