In order to compile a source code into a portable document format (pdf), it is required to install a $\TeX$ compiler ($\TeX$ distribution). If you are using Windows operating system, you can install a complete version of $MiK\TeX$, or $Pro\TeX t$. If your operating system is UNIX, you are recommended to install $\TeX live$. But if you are using MacOSX, you must install $Mac\TeX$.
