Произошла ошибка при запуске приложения с -platform eglfs
Я использую Yocto Project 2.4 и i.MX6 Quad sabreSD.
После того, как я собрал образ без Wayland и X11, я попытался запустить свое приложение с помощью команды ниже.
./Qt5_CinematicExperience -platform eglfs
К сожалению, у меня произошла ошибка, как показано ниже.
root@imx6qsabresd:/home# Qt5_CinematicExperience -platform eglfs
QEglFSVivIntegration will set environment variable FB_MULTI_BUFFER=2 to enable d
ouble buffering and vsync.
If this is not desired, you can override this via: export QT_EGLFS_IMX6_NO_FB_M
ULTI_BUFFER=1
