GLFW 3.3 for Go Build Status GoDoc


  • GLFW C library source is included and built automatically as part of the Go package. But you need to make sure you have dependencies of GLFW:
    • On macOS, you need Xcode or Command Line Tools for Xcode (xcode-select --install) for required headers and libraries.
    • On Ubuntu/Debian-like Linux distributions, you need libgl1-mesa-dev and xorg-dev packages.
    • On CentOS/Fedora-like Linux distributions, you need libX11-devel libXcursor-devel libXrandr-devel libXinerama-devel mesa-libGL-devel libXi-devel packages.
    • See here for full details.
  • Go 1.4+ is required on Windows (otherwise you must use MinGW v4.8.1 exactly, see Go issue 8811).
go get -u


If your target system only provides an OpenGL ES implementation (true for some ARM boards), you need to link against that implementation. You do this by defining the appropriate build tags, e.g.

go get -u -tags=gles2

Supported tags are gles1, gles2, gles3 and vulkan. Note that required packages might differ from those listed above; consult your hardware's documentation.


package main

import (

func init() {
	// This is needed to arrange that main() runs on main thread.
	// See documentation for functions that are only allowed to be called from the main thread.

func main() {
	err := glfw.Init()
	if err != nil {
	defer glfw.Terminate()

	window, err := glfw.CreateWindow(640, 480, "Testing", nil, nil)
	if err != nil {


	for !window.ShouldClose() {
		// Do OpenGL stuff.
