Linking objects causes "Can't be a weak definition" LD error

Hello everyone,

I'm using xcode 2.3 to compile a large application that is comprised of a target application and multiple sub-targets that build large object files. The application target and all sub targets build their object files without errors, but the linker tosses an undefined symbol error as follows:

undefined symbol 126062 (std::_Setfill<char> std::setfill<char>(char)) can't be a weak definition

I am linking to stdlibc++, and all calls to setfill are declared in the std namespace (IE: std::setfill). Can anyone suggest a reason why these aggregate object files would compile without fail, but the linker would complain. I also am wondering why the first part of that error message uses a capital 'S' while the function itself should be lowercase as it is printed in the second part of the error message.

Thoughts?

Thanks,

Aaron K.
