ld: duplicate symbol typeinfo


  • Subject: ld: duplicate symbol typeinfo
  • From: Jérôme Seydoux <email@hidden>

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

Jérôme
