Hi.
I'm trying to compile a C++ project in Eclipse on Mac OS X, and keep getting this error. I don't really know what it means, or how to fix it, and I've looked it up and haven't found much useful info on how to solve it. I'm almost positive I have all the libraries/headers that I'm trying to use properly installed as Eclipse seems to be able to use them in auto-complete. If you could please tell me what this error means and maybe how I can fix it that would be really helpful. Thanks
