HELP WITH CONIO! PLEASE

[Cirabou]

Hi, everyone! New here. I am working on a C++ project and I am trying to add some color to my console. I also want to use the clear screen function. Even though I installed conio.2, I keep getting an 'undefined reference' error.

At the beginning of my program, I have included the following libraries:
#include <cstdlib>
#include <iostream>
#include <conio.h>
#include <cmath>
#include <conio2.h>

Also, under 'compiler options' in the linker command line, I have the following (and only the following):
-lconio


I tried redownloading the conio package and it said it was already installed.

Can someone please, please help??? This project is due at eleven, and this is my final touch!

When i use conio.h i simply add it into my project and include it inside my header file and im set to use it. Do you have your headers added into your project?
