Hi Fabio, > I see only symbols "unexpected cases" and not build errors, I not have
Yes, that is the problem. Gcc 10 seemingly breaks practically all packages due to symbols changes - I am really surprised that this happens, is this on purpose? I will make updates to the packages after the long weekend we are having here (and a online conference I somehow co-organized).
