I got following error when trying to emerge media-video/vlc-9999: checking for x86_64-pc-linux-gnu-protoc... no checking for protoc... protoc checking protobuf-lite matches protoc version 23.3... yes checking for Qt5Core >= 5.12.0 Qt5Widgets Qt5Gui Qt5Quick Qt5QuickWidgets Qt5QuickControls2 Qt5Svg... no configure: error: Package 'Qt5Quick', required by 'virtual:world', not found Package 'Qt5QuickWidgets', required by 'virtual:world', not found Package 'Qt5QuickControls2', required by 'virtual:world', not found. If you want to build VLC without GUI, pass --disable-qt. !!! Please attach the following file when seeking support: !!! /var/tmp/portage/media-video/vlc-9999/work/vlc-9999/config.log * ERROR: media-video/vlc-9999::gentoo failed (configure phase): * econf failed * And I installed dev-qt/qtquickcontrols2 manually(with/without USE="widgets"),then I can emerge vlc Please check
Some build failure in 9999 can never be major.
