Hello I got a similar issue . error: 'SIOCGSTAMP' was not declared in this scope
The build fail due to bug in Qt qource bug : https://bugreports.qt.io/browse/QTBUG-76957
I add the recommended #include <linux/sockios.h>in qtwebengine/src/3rdparty/chromium/third_party/webrtc/rtc_base/physicalsocketserver.h to solve and continue the build
Does any patch is planned on ebuild ?
