Hi, Some warning messages @Thomas-Sparber

Thomas-Sparber commented 5 months ago

Hi, I just did the following:

In Makefile, I changed the C++ version to 17 by adding the flag -std=c++17. After that I recompiled everything and for me, everything is still working.

What you posted are just warnings, in my opinion you can ignore them and it should still work.

So unfortunately for me its not reproducible

Ok，tks.
