New to linux programming in C++ and need help

[jdoge13]

I'm trying to write out a very simple program (the one most people learn first that simply displays "Hello World") it works perfectly when I compile it in Dev C++ on my pc, however I'm getting a indecipherable (to me) error message below are the code and error. I think it must be some error with my compiler or with the iostream library. Any ideas? Thanks for any help in advance.

Code:
#include <iostream>
using namespace std;

main(){
cout << "Hello World." << endl;
}

(the only difference between this and the windows code is I used the system("pause"); command in the windows version)

The Error:

In ubuntu, you need to install the build-essential package in order to be able to compile anything:


sudo apt-get install build-essential


Also, make sure that you're using g++ to compile your C++ program (I mean, don't use gcc, which is the C compiler)

Thanks a lot...had no idea about the g++ thing, makes a big difference. haha.
