### Installing Dependencies
#### Installing MinGW (Windows only)
Building [raylib](https://github.com/raysan5/raylib) libraries requires the installation of MinGW ([32](http://www.mingw.org/) and [64](http://mingw-w64.org/doku.php/download) bit versions). Please ensure that all you link MinGW's `bin` directory to your system environment variables for BOTH the 32 and 64 bit versions. You can follow the instructions here for the [32-bit](https://www.youtube.com/watch?v=sXW2VLrQ3Bs) and here for the [64-bit](https://code.visualstudio.com/docs/cpp/config-mingw) bit versions.

After installing MinGW, you should be able to execute basic g++ commands. You can verify this by running the command:
After installing MinGW, you should have G++ installed. You can verify this by running:
```console
$ g++ --version
> g++ --version
g++ (x86_64-posix-seh-rev0, Built by MinGW-W64 project) 8.1.0
```
#### Installing G++ & Make (Linux only)
Some Linux distributions do not come preinstalled with the basic build tools required to do C/C++ development. In the case that you do not have them, you can install them all with one very handy meta-package aptly named `build-essential` using the following two commands:
```console
$ sudo apt update
$ sudo apt install build-essential
```
After installing the package, you should have both G++ and Make installed. You can verify this by running:
```console
$ g++ --version
g++ (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0
$ make --version
GNU Make 4.2.1
Built for x86_64-pc-linux-gnu
```
#### Installing ALSA, Mesa & X11 (Linux only)
On Linux, raylib is reliant on a number of libraries for audio, graphics, and windowing that may not come preinstalled, these being ALSA, Mesa & X11 respecively. Fortunately they can all be easily installed through your distribution's package manager with just a few lines:
##### Debian/Ubuntu
```console
$ sudo apt-get update
$ sudo apt install libasound2-dev mesa-common-dev libx11-dev libxrandr-dev libxi-dev xorg-dev libgl1-mesa-dev libglu1-mesa-dev
```
##### Fedora
```console
$ dnf check-update
$ sudo dnf install alsa-lib-devel mesa-libGL-devel libX11-devel libXrandr-devel libXi-devel libXcursor-devel libXinerama-devel
```
### Building the Project
1. Download the [raylib](https://github.com/raysan5/raylib) repository and generate a static library file (`.a` on UNIX-based systems or `.lib` on Windows) using the [build and installation instructions](https://github.com/raysan5/raylib#build-and-installation) in the repository README.
