不真实的源代码构建在xcode中挂起

Question

我正在尝试使用Unreal源代码和generated Xcode工作区来构建我的虚幻引擎项目。然而，Xcode或xcodebuild在构建过程开始后不久就挂起了。我在系统日志、构建日志中找不到任何有用的信息，或者任何关于为什么它会挂起的信息。不会花很长时间，我的CPU几乎是空闲的。

有没有人遇到过这个问题？我在Unreals论坛上已经两个多月没有收到关于这个话题的回复了。

我也遇到过类似的问题，我不能确定你是否也有同样的问题。但问题是，/bin/ps -eaw -o pid,comm可能会产生超过64K的输出数据。运行/bin/ps -eaw -o pid,comm | wc查看是否是这种情况。

这听起来可能很牵强，但在类MacBuildHostPlatform和方法GetProcesses()中的BuildHostPlatorm.cs中，会使用该命令进行进程调用：

    Proc.Start();
    Proc.WaitForExit();
    // ... then output is read

因此，如果输出大于管道缓冲区，命令就会卡住。在4.27中，通过移动Proc.WaitForExit()直到读取进程的输出，解决了这个问题。如果你使用的是早期版本，只需将WaitForExit();移到读取循环后的位置即可。
