GLFW 3.2 for Go

Installation

• 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).

et -u github.com/go-gl/glfw/v3.2/glfw

Usage

age main

rt (
"runtime"
"github.com/go-gl/glfw/v3.2/glfw"


 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()


 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()
}

Changelog

• 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.
