Objective C sources that include C++ have to have the suffix ".mm" instead of ".m" so that C++ features are enabled.

And to head off another question: the file that contains the main() for your app (usually main.m) needs to be a .mm (e.g., rename main.m to main.mm) to get xcode to link against the C++ standard library.

You may need to make any ObjC file that includes a C++ header into a .mm, which may be your own ObjC files. I don't exactly remember what it includes what.

Other than that, I'm not sure. It's a problem in your project setup. You can look at ScanTest for correct setup. It builds correctly.

int main(int argc, char *argv[]) {

NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
int retVal = UIApplicationMain(argc, argv, nil, @"myproject");
[pool release];
return retVal;
