Irrlicht Engine

I'm really struggling with drawing a 3d line and looking at it with a camera. Here's my code so far:

#include <irrlicht.h>
#include <iostream>
#include <cstdlib>
#include <conio.h>
#include <cmath>

using namespace std;
using namespace irr;
using namespace core;
using namespace video;
using ...

I'm trying to compile irrlicht with the gcc compiler in code::blocks, and I looked for the gcc library, but it's not there. Where can I get the library so I can compile my project?

I was looking through that, but I still can't find the problem. Here's the full code of the entire program:
#include <irrlicht.h>
#include <iostream>
#include <fstream>
#include <cstdlib>
#include <conio.h>
#include <stdio.h>
#include <string>
#include <vector>
#include <ctime>

using namespace ...

I'm trying to use the getSelected() function with my listbox, and every time I do it, I get this error:

Unhandled exception at 0x10010740 in dumb cake thing 2.exe: 0xC0000005: Access violation reading location 0x000000b1.

The code compiles fine, but when I actually select the item, this error is ...

Use this code just pauses the processor for a brief amount of time to let it cool down.

Thanks! I checked the console, and it was saying it couldn't open the .bmp file, and if it was made with the font tool, to try to open the .xml. Once I did this, the fonts are opening and displaying perfectly! Thanks again!

I created a font, made a font variable in my program, but when I try to display the font, it throws an unhandled exception error.

I am trying to display a timer in a corner of my screen and i need a descent sized font, but the game's default font is way too small. Can someone please point me to a bigger font? Thanks!
