Мне удалось кросс-скомпилировать qt 5.11.3 без проблем из ubuntu в raspbian stretch lite, следуя https://wiki.qt.io/RaspberryPi2EGLFS однако, когда я хочу запустить пример, я получаю следующее:
$export QT_LOGGING_RULES=qt.qpa.*=true && ./qopenglwidget -platform eglfs
qt.qpa.plugin: Could not load the Qt platform plugin "eglfs" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.
Aborted
если я использую платформу linuxfb, пример работает (без отображения анимации opengl, конечно).
Я пробовал много вещей, но, похоже, ничего не работает.Любая идея о том, как заставить это работать?
Мой конфиг сборки, если это поможет:
