Hi Suzuki-san Thank you very much When I add kms and gbm, it seems that the program can work. Thanks. Best regards Zhou Mingying From: Tasuku Suzuki <Tasuku.Suzuki@xxxxxx> Sent: Thursday, June 20, 2019 9:26 PM To: Zhou, Mingying/周 明英 <zhoumy@xxxxxxxxxxxxxx>; automotive-discussions@xxxxxxxxxxxxxxxxxxxxxxxxx Subject: RE: QtwaylandCompositor initialize error Hi, Can you check config.summary file which is generated during configure in qtbase? When gbm is available and enabled, a plugin called libqeglfs-kms-integration.so will be built. https://code.qt.io/cgit/qt/qtbase.git/tree/src/plugins/platforms/eglfs/deviceintegration/deviceintegration.pro?h=5.9 I recommend you to start simpler Qt apps such as qmlscene first with -platform eglfs. If it works, any QtWaylandCompositor apps should work with eglfs as a wayland compositor.

The strace detail is appendix "strace.log". Do anyone met the same problem before? Or Can you give me any advice to deal with this problem? The below is the details 1 Before I run the command ./minimal-qml, I add the eglfs to qtbase_%.bbappend, and make new agl-demo-platform image. - PACKAGECONFIG_GL = "${@bb.utils.contains('DISTRO_FEATURES', 'opengl', 'gles2', '', d)}<mailto:$%7b@bb.utils.contains('DISTRO_FEATURES',%20'opengl',%20'gles2',%20'',%20d)%7d>" + PACKAGECONFIG_GL = "${@bb.utils.contains('DISTRO_FEATURES', 'opengl', 'gles2 eglfs', '', d)}<mailto:$%7b@bb.utils.contains('DISTRO_FEATURES',%20'opengl',%20'gles2%20eglfs',%20'',%20d)%7d>" 2 After building image, I write it to a sd card, and start AGL. And I check that the eglfs plugin is installed.(See below ) ------------------------------------------------------- m3ulcb:~/wayland/minimal-qml# rpm -ql qtbase-plugins-5.9.7+git0+81b29a44d2-r0.aarch64 /usr /usr/lib /usr/lib/qt5 /usr/lib/qt5/plugins /usr/lib/qt5/plugins/bearer /usr/lib/qt5/plugins/bearer/libqconnmanbearer.so /usr/lib/qt5/plugins/bearer/libqgenericbearer.so /usr/lib/qt5/plugins/bearer/libqnmbearer.so /usr/lib/qt5/plugins/egldeviceintegrations /usr/lib/qt5/plugins/egldeviceintegrations/libqeglfs-emu-integration.so /usr/lib/qt5/plugins/generic /usr/lib/qt5/plugins/generic/libqevdevkeyboardplugin.so /usr/lib/qt5/plugins/generic/libqevdevmouseplugin.so /usr/lib/qt5/plugins/generic/libqevdevtabletplugin.so /usr/lib/qt5/plugins/generic/libqevdevtouchplugin.so /usr/lib/qt5/plugins/generic/libqtuiotouchplugin.so /usr/lib/qt5/plugins/imageformats /usr/lib/qt5/plugins/imageformats/libqjpeg.so /usr/lib/qt5/plugins/platforminputcontexts /usr/lib/qt5/plugins/platforminputcontexts/libibusplatforminputcontextplugin.so /usr/lib/qt5/plugins/platforms /usr/lib/qt5/plugins/platforms/libqeglfs.so /usr/lib/qt5/plugins/platforms/libqminimal.so /usr/lib/qt5/plugins/platforms/libqminimalegl.so /usr/lib/qt5/plugins/platforms/libqoffscreen.so /usr/lib/qt5/plugins/platforms/libqvnc.so /usr/lib/qt5/plugins/sqldrivers /usr/lib/qt5/plugins/sqldrivers/libqsqlite.so ------------------------------------------------------- 2 the env of my environment is ------------- m3ulcb:~# export QT_QPA_EGLFS_KMS_CONFIG="/etc/kms.conf" m3ulcb:~# export XDG_RUNTIME_DIR=/run/user/0 m3ulcb:~# env LD_LIBRARY_PATH=/usr/lib EDITOR=vi XDG_SESSION_ID=c1 HUSHLOGIN=FALSE USER=root PWD=/home/0 HOME=/home/0 QT_QPA_EGLFS_KMS_CONFIG=/etc/kms.conf MAIL=/var/spool/mail/root SHELL=/bin/sh TERM=xterm SHLVL=1 QT_QPA_PLATFORM=wayland LOGNAME=root DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/0/bus XDG_RUNTIME_DIR=/run/user/0 PATH=/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin PS1=\h:\w\$ _=/usr/bin/env --------------------- Best regards, Zhou Mingying ----------------------------------------------------------------------------- Nanjing Fujitsu Nanda Software Tech.
