[C++] How do I correct this: warning LNK4221: no public symbols found ... ?

Means that the .obj file has no public symbols exported. The solution is to remove any such .obj files from the link stage.

What do you mean by 'public symbols'?

He means exported symbols that would be seen by the other translation units. For example, a function, a class member, a global variables, and so on.

Thanks, but how do any of those get public/private?

In other words, what's really going on is that the particular .obj file doesn't contain any code that will end up in your .exe

You have compiled a .c/.cpp, but you haven't called any of the functions/class members from it in your application, so the .obj file won't be used to create the .exe

Does that make sense to you?

"public", as used, doesn't mean the same thing as "public:" in a class declaration, btw.
