This fork is to merge the implementation of the new GLFW Vulkan functions from vulkan-go/glfw into the current go-gl/glfw codebase.
- 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
andxorg-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.
- On macOS, you need Xcode or Command Line Tools for Xcode (
- Go 1.4+ is required on Windows (otherwise you must use MinGW v4.8.1 exactly, see Go issue 8811).
go get -u github.com/go-gl/glfw/v3.3/glfw
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 github.com/go-gl/glfw/v3.3/glfw
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 (
"runtime"
"github.com/go-gl/glfw/v3.3/glfw"
)
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.
runtime.LockOSThread()
}
func main() {
err := glfw.Init()
if err != nil {
panic(err)
}
defer glfw.Terminate()
window, err := glfw.CreateWindow(640, 480, "Testing", nil, nil)
if err != nil {
panic(err)
}
window.MakeContextCurrent()
for !window.ShouldClose() {
// Do OpenGL stuff.
window.SwapBuffers()
glfw.PollEvents()
}
}
- Joystick functions now uses receivers instead of passing the joystick ID as argument.
- Vulkan methods are intentionally not implemented.
Window.Handle
can be used to create a Vulkan surface via the this package.

- Easy
go get
installation. GLFW source code is now included in-repo and compiled in so you don't have to build GLFW on your own and distribute shared libraries. The revision of GLFW C library used is listed in GLFW_C_REVISION.txt file. - The error callback is now set internally. Functions return an error with corresponding code and description (do a type assertion to glfw3.Error for accessing the variables) if the error is recoverable. If not a panic will occur.
