Dear ROOTers, Is there “nice looking” way to load given namespaces in my macro? Lets say that I have MyLib that contains MyNamespace and MyClass. Now I have to use MyClass before calling namespace e.g. MyClass *d = 0x0; Int_t val = MyNamespace::Something(); I tried to call gSystem->Load(“MyClass…

I tried to include “raw” MyNamespace.h but it gives me error "IncrementalExecutor::executeFunction: symbol X unresolved while linking [cling interface function]!. C++fil…
