Hey @zerotrzy, do you have a problem completing the build, or are you just pointing out that the compiler generates a number of warnings, but the build is successful. I've noticed this also, but I haven't had time to dig in and resolve the warnings, I have a hard enough time keeping up with the bugs 😝
