C++ undefined reference to WinMain@16 (Code::Blocks)

Question

I\'m learning C++ with Code::Blocks, and everytime i try to create a new class, I get an error message saying:

undefined reference to `WinMain@16\'
         


        

Answer 1

I just had this issue too! The problem was that I put my main function under a specific namespace while my classes were not part of this namespace and looked like I have no "main" for them. As soon as I removed the namespace/added the classes to the same namespace the build issue was gone.
