macOS 'Undefined symbols' when using std c++ libraries

[sammich]

In something as simple as:

#include <iostream>
using namespace std;

int main() {
	return 0;
}

I get a list of the undefined symbols bookended by "ld: symbol(s) not found". I am compiling using just gcc -o test test.cc, something which has worked in the past.

I have XCode 3.2 (1610) installed. And making a project as a CLI tool (10.6) and building it works.

And preferably I'd like to keep from downloading XCode all over again as I don't exactly have a that much bandwidth for the month to spare.

What happened? I haven't used C++ in a while as I was doing a course that required straight C so I don't know where things stopped working.

Updated my post above:

Building the code as a CLI tool in XCode as a 10.6/10.5 executable works without a hitch.

So are there some extra arguments that I need to give to gcc to get it to compile properly?

Are you sure you are compiling it right?

g++ test.cpp -o test

g++ test.cpp -o test

Ouch. You can can really tell I've been away from C++ for too long and attached to C.

Thanks for not mocking me
