我正在尝试编译WSL中新安装的PCL库。我遵循了线程中给出的步骤：https://stackoverflow.com/questions/58040066/how-to-compile-point-cloud-library-pcl-with-examples-ubuntu。我安装了线程中提到的所有必需的依赖项，但遇到编译错误。

Projects should be ported to the NEW behavior and not rely on setting a policy to OLD.

你试图在一个WSL上编译，它只是一个子系统，也就是说，它没有一个X-server。就这么简单。看这一行：
长话短说，你不可能在WSL上编译它，因为VTK需要一个X-server来实现它的可视化，你需要从启动和运行X-server开始。我真的不知道这将如何在WSL上运行，即使你有一个X-server来处理WSL，但是我可能错了。
编辑：显然，通过转发它可以让一个X服务器在WSL上工作，但我仍然相信（特别是因为你是新来的），这比仅仅让一个双引导工作要多得多。
编辑2：Tsyvarev很好心地提供了一个关于如何获得X-server configured on WSL的很棒的链接。
