I was working on some stuff for work and ran into this snag:

It's a very basic hello world, it uses <iostream> and cout. It doesn't want to compile. Now the even odder thing, is that my OpenGL/SDL code compiles fine without any errors. It doesn't use <iostream> though, so it sort of appears that iostream doesn't want to work. Or I'm including it wrong. I've tested this on 2 different gentoo systems. Just looking for a push in the right direction. Thanks.
#include <iostream>
using namespace std;
int main () {
cout << "hello world!" << endl;
}
gcc file.cpp -Wall -o test
I'm not compiling as root, if that helps.

Use g++ not gcc to compile C++ code (to link against the proper
libstdc++). |

| Well, gcc isn't a C++ compiler, use g++ for that. |
