Oh, I forgot to post the build log.  Here it is:

Hope that may help shed some light(some names have been changed).

Thanks again.

Hello all,

I'm getting some strange linking errors in my project. It's all C+ + and I'm getting errors about these symbols being undefined.

__ZnwmPv
__ZdlPvS_

The only thing that the files referenced have in common is that they all use "new". I've tried linking explicitly to libstdc++ but that doesn't make a difference.

The only thing that I've found online was a post from late last year. They recommended using a unexported symbols file, which I tried to no avail. Any ideas?

Thanks in advance!
