First a general question since this happens from time to time. Is reports of failing compilations better reported in the official tracker? It is not a Blender bug really. But a development step has a flaw, a windows or linux version does not work with linux or windows specific changes and slipped throug. A forgotten semicolon, a not defined variable. One rushed untested push, and we have a commit in the master that prevents it from compilation. This simply happens from time to time.
Now to the problem. The current Blender version simply fails to compile. The trouble maker is a new commit. UV: implement copy and paset for UV. uint8_t not defined in uvedit_clipboard_graph_iso.hh
Could you please fix it
