Hi, When building qt-3.3.8 and wxGTk on Tru64 UNIX 5.1 (alphaev67-dec-osf5.1) with gcc-4.2.4, we got linker failures about duplicate non-virtual thunks, e.g. from qt: /usr/ccs/bin/ld: .obj/release-shared-mt/qmotifdnd_x11.o: non-virtual thunk to QDragMoveEvent::~QDragMoveEvent(): multiply defined .obj/release-shared-mt/qmotifdnd_x11.o: non-virtual thunk to QDragMoveEvent::~QDragMoveEvent(): multiply defined .obj/release-shared-mt/qmotifdnd_x11.o: non-virtual thunk to QDragEnterEvent::~QDragEnterEvent(): multiply defined .obj/release-shared-mt/qmotifdnd_x11.o: non-virtual thunk to QDragEnterEvent::~QDragEnterEvent(): multiply defined
This appears to be because the non-virtual thunks are not output weak on this platform, so, those that appear in multiple objects will cause linker errors like this (in the above case, there are _ZThn16_N14QDragMoveEventD0Ev and _ZThn16_N14QDragMoveEventD1Ev in both qdnd_x11.o and qmotifdnd_x11.o). Tru64 appears to have some weak symbol support, is there a reason that these thunks are not weak? Peter -- Peter O'Gorman po...@thewrittenword.com
