A program that I've been working on for a while, that I upgraded from Xcode 2 to Xcode 3 when I upgraded to Leopard, has been manifesting weirdness in regarding certain symbols as multiply defined when I don't think they are.

I had similar problems, but managed to resolve them today. Our projects may have appeared to work correctly in Xcode 2 due to Zerolink, which is no longer used in Xcode 3. These discussions gave me some useful clues:

In my case, there were several constants with the same names declared in different files.

I wanted to share some of these constants between the files. I fixed these by sorting out my declarations ("extern <type> const <varname>") and definitions "<type> const <varname> = <value>".

I wanted other constants to be private to the individual files concerned - fixed by prefixing the definition with "static".

Hope this helps with resolving your problems.
