I cross compile qt5. Here is the config

load(qt_config)
I found that if I close -eglfs, config is ok, opengl is opened. But EGL---no If I turn on -eglfs. It will show the error
ERROR: Feature 'eglfs' was enabled, but the pre-condition '!config.android && !config.darwin && !config.win32 && features.egl' failed.
The link is 404. https://doc.qt.io/QtForDeviceCreation/qtee-preparing-hardware-jetsontx1.html
I want to us eglfs and any suggestions？
