Supported Platforms

Quickstart supports the main 3 desktop platforms:

• Windows
• Linux
• MacOS

VSCode Users (all platforms)

Note You must have a compiler toolchain installed in addition to vscode.

• Download the quickstart
• Rename the folder to your game name
• Open the folder in VSCode
• Press F5 to build
• You are good to go

Windows Users

There are two compiler toolchains available for windows, MinGW-W64 (a free compiler using GCC), and Microsoft Visual Studio

Using MinGW-W64

• Double click the build-MinGW-W64.bat file
• CD into the folder in your terminal
• run make
• You are good to go

Note on MinGW-64 versions

Make sure you have a modern version of MinGW-W64 (not mingw). The best place to get it is from the W64devkit from https://github.com/skeeto/w64devkit/releases or the version installed with the raylib installer

If you have installed raylib from the installer

Make sure you have added the path

C:\raylib\w64devkit\bin

To your path environment variable so that the compiler that came with raylib can be found.

DO NOT INSTALL ANOTHER MinGW-W64 from another source such as msys2, you don't need it.

Microsoft Visual Studio

• Run build-VisualStudio2022.bat
• double click the .sln file that is generated
• develop your game
• you are good to go

Linux Users

• CD into the build folder
• run ./premake5 gmake2
• CD back to the root
• run make
• you are good to go

MacOS Users

• CD into the build folder
• run ./premake5.osx gmake2
• CD back to the root
• run make
• you are good to go

Output files

The built code will be in the bin dir

Working directories and the resources folder

The example uses a utility function from path_utils.h that will find the resources dir and set it as the current working directory. This is very useful when starting out. If you wish to manage your own working directory you can simply remove the call to the function and the header.

Building for other OpenGL targets

If you need to build for a different OpenGL version than the default (OpenGL 3.3) you can specify an OpenGL version in your premake command line. Just modify the bat file or add the following to your command line

For OpenGL 1.1

--graphics=opengl11

For OpenGL 2.1

--graphics=opengl21

For OpenGL 4.3

--graphics=opengl43

For OpenGLES 2.0

--graphics=opengles2

For OpenGLES 3.0

--graphics=opengles3

Thanks

Special thanks to the massively helpful Raylib and EnTT communities. Thanks to Jeffery Meyers for providing the build boilerplate
