raylib-go

Golang bindings for raylib, a simple and easy-to-use library to enjoy videogames programming.

raylib C source code is included and compiled together with bindings. Note that the first build can take a few minutes.

It is also possible to use raylib-go without cgo (see requirements below).

Requirements

cgo

Ubuntu

apt-get install libgl1-mesa-dev libxi-dev libxcursor-dev libxrandr-dev libxinerama-dev libwayland-dev libxkbcommon-dev

Fedora

dnf install mesa-libGL-devel libXi-devel libXcursor-devel libXrandr-devel libXinerama-devel wayland-devel libxkbcommon-devel

macOS

On macOS, you need Xcode or Command Line Tools for Xcode (if you have brew installed, you already have this).

Windows

On Windows you need C compiler, like Mingw-w64 or TDM-GCC. You can also build binary in MSYS2 shell.

To remove console window, build with -ldflags "-H=windowsgui".

Android

Android example.

Wasm

For web bindings, refer to Raylib-Go-Wasm; it should be largely compatible with this repository.

purego (without cgo, i.e. CGO_ENABLED=0)

You can use raylib-go on Linux, macOS, Windows and FreeBSD without the need of cgo. 32-bit is not supported.

The shared libraries (.dll, .so, .dylib) of raylib are already embedded for Linux arm64/amd64, macOS arm64/amd64 and Windows arm64/amd64. The build tag raylib_no_embed or the environment variable RAYLIB_NO_EMBED=1 can disable this feature.

Installation

go get -v -u github.com/gen2brain/raylib-go/raylib

Build tags

• drm - build for Linux native DRM mode, including Raspberry Pi 4 and other devices (PLATFORM_DRM)
• sdl - build for SDL backend (PLATFORM_DESKTOP_SDL)
• sdl3 - build for SDL3 backend (PLATFORM_DESKTOP_SDL3)
• rgfw - build for RGFW backend (PLATFORM_DESKTOP_RGFW)
• noaudio - disables audio functions
• opengl43 - uses OpenGL 4.3 backend
• opengl21 - uses OpenGL 2.1 backend (default is 3.3 on desktop)
• opengl11 - uses OpenGL 1.1 backend (pseudo OpenGL 1.1 style)
• es2 - uses OpenGL ES 2.0 backend (can be used to link against Google's ANGLE)
• es3 - experimental support for OpenGL ES 3.0
• x11 - force X11 compatibility mode on Wayland (PLATFORM_DESKTOP/GLFW)
• wayland - force Wayland only mode (PLATFORM_DESKTOP/GLFW)
• raylib_no_embed - doesn't embed the pre-build shared libraries (only applies to purego version)

Example

package main

import rl "github.com/gen2brain/raylib-go/raylib"

func main() {
  rl.InitWindow(800, 450, "raylib [core] example - basic window")
  defer rl.CloseWindow()

  rl.SetTargetFPS(60)

  for !rl.WindowShouldClose() {
    rl.BeginDrawing()

    rl.ClearBackground(rl.RayWhite)
    rl.DrawText("Congrats! You created your first window!", 190, 200, 20, rl.LightGray)

    rl.EndDrawing()
  }
}

Cross-compile (on Linux with cgo)

To cross-compile for Windows install MinGW toolchain.

$ CGO_ENABLED=1 CC=x86_64-w64-mingw32-gcc GOOS=windows GOARCH=amd64 go build -ldflags "-s -w"
$ file basic_window.exe
basic_window.exe: PE32+ executable (console) x86-64 (stripped to external PDB), for MS Windows, 11 sections

$ CGO_ENABLED=1 CC=i686-w64-mingw32-gcc GOOS=windows GOARCH=386 go build -ldflags "-s -w"
$ file basic_window.exe
basic_window.exe: PE32 executable (console) Intel 80386 (stripped to external PDB), for MS Windows, 9 sections

To cross-compile for macOS install OSXCross toolchain.
