Why don’t include guards make a circular #include work?
The preprocessor is a program that takes your program, makes some changes (for example include files (#include), macro expansion (#define), and basically everything that starts with #) and gives the “clean” result to the compiler. The preprocessor works like this when it sees #include: When you write: #include “some_file” The contents of some_file almost literally …

This is not a compiler error: the error is coming from the linker. After compilation, the linker will merge the object files resulting from the compilation of each of your translation units (.cpp files). The linker finds out that you have the same symbol defined multiple times in different translation units, and complains about it …
