I am getting link errors using Xcode with the 3.3 compiler targeting the
10.2.8 SDK (although the SDK is not really relevant here).
I am compiling and linking a library, then using that library to compile
and link a program.
The link errors are similar template instantiations.
I have done some digging using nm.
The missing symbols all appear twice in the library. Once with a "U" and
once with an "S" including an address. However, when the program is
linked with the library, the symbols are not found.
As an experiment, I added one of the source files to the application and
it was able to locate that symbol.
It is also interesting to note that I had been using gcc 4 and didn't
have these link errors. So this seems something to do with gcc 3.3.
Why isn't the linker locating the symbols in the library? What do I need
to do to get the symbols to resolve.
Thank you for your help,
...Duane
