mac vagrantでGLUTのGUIの立ち上げ方法

VagrantでGULTのGUIが立ち上がらない

#include <GL/glut.h>

void display(void){

}

int main(int argc, char *argv[]){
	glutInit(&argc, argv);
	glutCreateWindow(argv[0]);
	glutDisplayFunc(display);
	glutMainLoop();
	return 0;
}

$ ./app
freeglut (./app): failed to open display ”

1.一旦ログアウトしてvagrantを止めます。

$ exit
$ vagrant halt

2. Vagrantfileにssh.forward_x11を追記します。

Vagrantfile

Vagrant.configure("2") do |config|
  config.vm.box = "ubuntu/bionic64"
  config.vm.network "private_network", ip: "192.168.33.10"
  config.ssh.forward_x11 = true　//　追加
end

https://www.vagrantup.com/docs/vagrantfile/ssh_settings.html
config.ssh.forward_x11 (boolean) – If true, X11 forwarding over SSH connections is enabled. Defaults to false.

X Window Systemとは、UNIX系OSで標準的に用いられるウィンドウシステム。

XQuartzをダウンロード
-> MacユーティリティでXQuartzを起動し、terminalから再度実行

あれ、何故だーーーーーーーーーー
色々検索していたところ、同じ解決方法を発見

Try the following: 1) ensure you are running up-to-date Xquartz. 2) in a terminal, defaults write org.macosforge.xquartz.X11 enable_iglx -bool true 3) restart xquartz. This worked for me to get a simple java app running. I tried "glxgears" and it starts, but the gears don't turn. I presume they're supposed to

mac側のterminalでX11をenableにする。
$ defaults write org.macosforge.xquartz.X11 enable_iglx -bool true

再度XQuartzでsshログイン
$ ./app
