[unable to compile and link C++ code with g++ 12.3]

[Maxim Abalenkov]

Dear Dave et al.,

I’m unable to run the ‘xcodebuild —version’. It complains:

xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

The version of Xcode reported by the ‘About Xcode’ graphical menu item is:

Version 15.0 (15A240d)
