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
立ち上がったーーーーーーーーーーーー
