PIXEL fails compile

[godfather667]

When compiling the following program and others I have problems like this:

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

In file included from ./glfw/src/internal.h:169:0,
from ./glfw/src/context.c:28,
from ../github.com/go-gl/glfw/v3.2/glfw/c_glfw.go:4:
./glfw/src/x11_platform.h:39:10: fatal error: X11/Xcursor/Xcursor.h: No such file or directory
#include <X11/Xcursor/Xcursor.h>
^~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

I get similar errors with GL Library Components.

Can I assume that this is a problem with the version I am using??

package main 
import (
	"github.com/faiface/pixel"
	"github.com/faiface/pixel/pixelgl"
	"golang.org/x/image/colornames"
)

func run() {
	cfg := pixelgl.WindowConfig{
		Title:  "Pixel Rocks!",
		Bounds: pixel.R(0, 0, 1024, 768),
		VSync:  true,
	}
	win, err := pixelgl.NewWindow(cfg)
	if err != nil {
		panic(err)
	}

	win.Clear(colornames.Skyblue)

	for !win.Closed() {
		win.Update()
	}
}

func main() {
	pixelgl.Run(run)
}

Have you installed requirements as described here?

Are you using dep to manage your dependencies @godfather667?

I ran into a similar problem, where any directories under https://github.com/go-gl/glfw/tree/master/v3.2/glfw/glfw failed to vendor and caused a compilation crash.

Not an issue with faiface/pixel, definitely a dependency issue - Found this specific error coming from https://github.com/go-gl/glfw/blob/master/v3.2/glfw/glfw/src/x11_platform.h#L39. Was able to fix by making sure I had all contents of https://github.com/go-gl/glfw/tree/master/v3.2/glfw/glfw properly loaded.

I had a glfw issue as well, I had to manually put it in the right place. It was a while ago, but I remember copying ?/glfw/glfw/ to somewhere.

Compilation fails for me too, even though I have all of the required packages installed:

@domust are you sure that's failing to compile? Those are the expected warning messages from GLFW. See: #143

[fgrosse]

Maybe this issue is now resolve since we upgraded to Go modules to track specific versions and also we are now on GLFW 3.3?

[AlexMapley]

Yeah I would say so too @fgrosse, this issue isn' really relevant anymore with go mod.

[fgrosse]

Cool, @delp I think we can close this then now 😃
