ld: duplicate symbol typeinfo

  • Hello,

    After migrating to Mac OS X 10.5 and XCode 3, I have the following link
    error in my project:

    ld: duplicate symbol typeinfo for TArray<long>in CMailBrowser.o and CPMApp.o

    CMailBrowser.o and CPMApp.o are two c++ classes, which have some
    PowerPlant classes in common in their superclasses. Some of these
    superclasses have a member variables of class TArray, which is a
    PowerPlant template class.

    I don't understand what this link error means, why it was not occurring
    with previous versions of XCode, and what can I do to fix it?

    Thanks for any help
