Hi, could anybody give me a hint regarding the folloing errors I get from the linker when linking a particular program: /usr/ccs/bin/ld: Duplicate symbol "vtable for BCDumper" in files FM_PFC.o and /l home/braisch/modbau/obj/libMF.a(MFModel.o) /usr/ccs/bin/ld: Duplicate symbol "VTT for BCDumper" in files FM_PFC.o and /lhom e/braisch/modbau/obj/libMF.a(MFModel.o) /usr/ccs/bin/ld: Duplicate symbol "typeinfo for BCDumper" in files FM_PFC.o and /lhome/braisch/modbau/obj/libMF.a(MFModel.o) /usr/ccs/bin/ld: Duplicate symbol "construction vtable for std::basic_ostream<ch ar, std::char_traits<char> >-in-BCDumper 0" in files FM_PFC.o and /lhome/braisch /modbau/obj/libMF.a(MFModel.o) Strangely, the code links correctly with gcc 3.3.1 on HP-UX 11.0, but I need 10.20. Could it be the case that something is wrong with the installation of the compiler? Thanks, Andreas Geisler > SIEMENS I&S IP PEP AD P.O.
