java - Mac 上未设置 X11 DISPLAY 变量

Question

我正在从终端运行应用程序。预计将推出一个特定于应用程序的调试器 GUI，在内部与 GDB 对话。我尝试过 {export DISPLAY=localhost:0.0} & {export DISPLAY=:0.0}。这是行不通的。在我的 Linux 机器上，我能够运行该应用程序，而无需设置 DISPLAY。

No X11 DISPLAY variable was set, but this program performed an operation which requires it.

Mac 默认情况下不运行 X11(Mac 上的核心桌面环境也称为 Quartz )。您需要安装(并运行)X 服务器。每Apple support

X11 is no longer included with OS X, but X11 server and client libraries for OS X are available from the XQuartz project.

XQuartz可用。
