C++ compiling problem

[lukasmaci]

Hello, I am trying to compile my first Hello world program in C++.
I have installed g++ by Synaptic and I have written this code

#include <iostream>
using namespace std;

int main()
{
cout << "Hello world";
return 0;
}


If I try to compile it g++ prvni.cpp -o prvni g++ writes me this

and many many others errors.
Please, could you tell me what to do.
Thank you very much.

sudo apt-get install build-essential

gcc is only the compiler, you also need all the standard libarys and the like.

[narcolept]

it appears you're missing libraries. apt-cache search g++ and look for library/devel packages, and this should work for you. What the errors are saying is that it's missing those funtions. all g++ itself is is the compiler, you need libraries and header files in order to compile.

As Gord says, installing build-essential is ... well essential for Developing C++ programs. That should solve your problem.

After compiling a few programs by hand, just to see how it works , I highly suggest to install Anjuta the integrated development package.

[AndreiCiprian]

I have installed build-essential and anjuta too.
Things are working perfectly no matter what solution I choose: terminal or ide.
