I rebased my changes onto current LibreELEC Maser and now i can't compile it because there is no gpu-sunix drivers on master and getbuildplan.py failing to collect dependencies
Am I doing something wrong?
You missed something, because gpu-sunxi doesn't exist for some time now. It's replaced by mali-utgard package and it's selected as dependency automatically. I don't know what your changes are, but I would just remove this dependency.
i run an orange pi pc plus and i would like to know if we can expect one day to have an eMMC install script ?
As I stated few post above, there are no deadlines for any feature. In principle, you can just flash image to eMMC via ssh and it should work. Somebody wrote quick guide in this topic how to do that.
