A class declared in this way: --- namespace test { class test; } class test::foo { test(); }; --- is not imported, only the namespace is created. On the other side a class declared properly in this way --- namespace test2 { class foo { test2(); }; } --- imports both the namespace and the class. The first example is valid c++ code, therefore I'd expect them to produce the same result.

Domenichelli from comment #0) > A class declared in this way: > > --- > namespace test { > class test; You declare class test to be a member of namespace test > } > > class test::foo You define a class foo inside test, which is not declared in namespace test above > { > test(); > }; > --- This is not supported by the c++ standard. See http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n4296.pdf 7.3.1.2 Namespace member definitions 2 Members of a named namespace can also be defined outside that namespace by explicit qualification of the name being defined, provided that the entity being defined was already declared in the namespace and the definition appears after the point of declaration in a namespace that encloses the declaration’s namespace. The correct c++ fragments looks then --- namespace test { class foo; } class test::foo { test(); }; ---- Importing this code creates class test::foo.
You are right, sorry, that was all caused by a typo while trying to reproduce my issue that is actually different... The problem is that the classes are generated, but the methods are not imported for example see the difference in the classes foo and bar generated by this: --- namespace test { class foo; class bar { bar(); }; } // namespace test class test::foo { test(); }; ---
