Question

I have some C++ source code with templates maybe like this – doxygen runs without errors but none of the documentation is added to the output, what is going on?

/// /// A class /// class A {   ///   /// A typedef   ///   typedef B<C<D>> SomeTypedefOfTemplates; }; 

Answer 1

Yeah, so what is going on is the template instantiation is bogus. The ‘>>’ like that is ambiguous and is meant to be a compile time error. You couldn’t see it because maybe your compiler (VC++) let it slip by but I guess doxygen was stricter on that. Add a space like shown.

/// /// A class /// class A {   ///   /// A typedef   ///   typedef B<C<D> > SomeTypedefOfTemplates; };
