Hello,

You can ignore that, it's to build the documentation (the same as the
web site), or you can install doxygen.

That's right, you need to instantiate the Repository singleton before
you can call any of its functions. It doesn't have to be static, it
just has to persist for as long as your program uses it.
You could put this at the top of your main function:
ObjectHandler::Repository repository;
Please have a look at the ExampleCpp project.
