c++ compilation

When I invoke the c++ compiler in macOS Big Sur Version 11.5.1 (20G80) I get the following:

objc[80581]: Class AMSupportURLConnectionDelegate is implemented in both /usr/lib/libauthinstall.dylib (0x20cbc3ad8) and /System/Library/PrivateFrameworks/MobileDevice.framework/Versions/A/MobileDevice (0x1165dc2b8). One of the two will be used. Which one is undefined.

objc[80581]: Class AMSupportURLSession is implemented in both /usr/lib/libauthinstall.dylib (0x20cbc3b28) and /System/Library/PrivateFrameworks/MobileDevice.framework/Versions/A/MobileDevice (0x1165dc308). One of the two will be used. Which one is undefined.

My question: What to do about these messages?

Thanks in advance,

This is log noise that you can ignore. It has nothing to do with your C++ code.
