I am attempting to compile the nearest neighbors example (https://github.com/jclay/cppyy-knearestneighbors-example), using cppyy 2.4.2. I am getting the following errors at the linker stage:

It seems like maybe a library is not being properly included?

I am also getting the line CRITICAL: While parsing: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1/wchar.h:123[15] 'wchar.h' file not found but it does not seem to halt the make process.

Not sure about the first (it's not my code, so haven't tried it in a long while), but for the last, MacOS has been moving the standard headers around, so now older versions of Cling can no longer find them automatically. You need to use cppyy 3.1.0 to find the automatically again or supply the paths manually.
