In this case supportsService is a macro. Multiple inheritance of the same UNO interface does happen, and you then need to help the compiler by static_casting this to one of the branches through which it is inherited. (Though multiple inheritance of XServiceInfo rather smells like a design bug that should be cleaned up.) Unwind the use of IMPLEMENT_SERVICE_INFO3 in dbaccess/source/core/api/query.cxx, find out through which branches XServiceInfo is inherited, and use a static_cast around the this pointer in the implementation of OQuery::supportsService. -- You are receiving this mail because: You are on the CC list for the bug.
