Hi,
I assume that GL is enabled and supported on your device, so hardware can be excluded as the trouble maker.
LD_LIBRARY_PATH points out of the sysroot. I wouldn’t recommend to use it at all in cross compile environments. Better to set an RPATH instead.On a side note: Ubuntu 24 isn’t supported yet. We’re working on it. Better try 22, just to exclude one more potential issue.

Okay thank you. I am now working on
Ubuntu 22.04.5 LTSI believe I may have only one problem to solve now. How to influence
