dumpcpp doesn't generate correct code for a reference to an enum value, it generates something like:

inline void GetEntry(int index, int& hMemberPad, A_RTM_OPERATION& iOperation, int& lDataPeriod);

when it should be in the relevant namespace like:

inline void GetEntry(int index, int& hMemberPad, AltiComLib::A_RTM_OPERATION& iOperation, int& lDataPeriod);
