I just started using Irrlicht and when I compile the program it gives me this error: cannot find -lirrlicht.
Theres no point in posting the code because I all have are the iostream and irrlicht.h includes and the main function returning 0.
IDE: Code::Blocks
Irrlicht: 1.7.3
OS: Ubuntu 10.11
I've searched online, but I couldn't find an answer.
Getting an error when I compile Irrlicht
Where is libirrlicht(.a/.so/...)? You need to point the linker to it. Pass "-L <path-to-your-libs>" on the command line to do this. There's probably something in one of the Code::Blocks dialogs to set this via a GUI.
I said this in the other thread, but I'll say it again here for you in bold: Now's a really good time to read up on the C and C++ compilation model. Once you have a good understanding of that, fixing problems such these becomes very easy.

Thanks for the answer, I was able to solve the problem. And thank you for your advice, I'll look into it.

I just started following a tutorial and this is the code I added to my program:
IrrlichtDevice *device=createDevice(EDT_OPENGL, dimension2d<u32> (640, 480), 16, false, false, false, 0);
if(!device)
{
return 1;
}
and for the past two hours I've been looking for some way to solve these errors:

Did you add the irrlicht lib?
A fast way :
[source]
#pragma comment(lib, "irrlicht.lib") // Or irr.lib can't remember
[/source]

Which libraries contain those symbols? You will need to tell your linker about them, either by adding them on the command line, or by setting the appropriate option in the Code::Blocks GUI.
I guess you might need something like libx11 and libglx, but I don't have a Linux system handy to check their names.
This is another very common, easily solvable linker error. You will encounter this problem time and time again. They are very easy to fix with a little bit of knowledge. So, one last time, after which I give up: Now's a really good time to read up on the C and C++ compilation model. Once you have a good understanding of that, fixing problems such these becomes very easy.

That line of code is only used if your using Microsoft Visual Studio. I'm using Code::Blocks.

Well, could you please give me a book title that talks about this or maybe a website name...
