When writing a lcg dictionary for a converter class using a custom std container, as

std::vector<UserDefNamespace::UserDefEnum>

lcg dictionary must know all related classes that are used.

So in selection.xml file one should have:

<class name=”std::vector<UserDefNamespace::UserDefEnum>” />

<class name=”std::vector<UserDefNamespace::UserDefEnum>::iterator” />

because probably also the iterator will be used. Same applies also for PackageDict.h file.

Be aware that for a std::map also the std::pair definition is needed.
