Hallo! I have built and installed gcc 4.3.2 on Tru64 v5.1 on alpha and now trying to build qt4 library. At some point the following errors occur when linking shared library: .obj/release-shared/qtcpsocket.o: non-virtual thunk to QAbstractSocketPrivate::exceptionNotification(): multiply defined .obj/release-shared/qtcpsocket.o: non-virtual thunk to QAbstractSocketPrivate::proxyAuthenticationRequired(QNetworkProxy const&, QAuthenticator*): multiply defined .obj/release-shared/qtcpsocket.o: non-virtual thunk to QAbstractSocketPrivate::writeNotification(): multiply defined .obj/release-shared/qtcpsocket.o: non-virtual thunk to QAbstractSocketPrivate::readNotification(): multiply defined .obj/release-shared/qudpsocket.o: non-virtual thunk to QAbstractSocketPrivate::exceptionNotification(): multiply defined .obj/release-shared/qudpsocket.o: non-virtual thunk to QAbstractSocketPrivate::proxyAuthenticationRequired(QNetworkProxy const&, QAuthenticator*): multiply defined .obj/release-shared/qudpsocket.o: non-virtual thunk to QAbstractSocketPrivate::writeNotification(): multiply defined These methods are declared as abstract in base class and then explicitly defined in derived class directly in class declaration (as inline). If I leave only declarations in derived class and define the actual method bodies in .cc file, then errors dissappear. I suspect the problem is related to tru64 linker. Did anybody here have similar problem? Maybe some patch should be applied to tru64? Or some option can be given to g++? Regrettably just fixing these two files is not enough, it seems to occur for all virtual methods defined directly in class definitions :-( Best regards, -- \ / | Michael Ivanov.
