为什么GDB调试器不断冻结Xcode 4？ [英] Why does GDB debugger constantly freeze Xcode 4?

问题描述

我正在使用摄像头Feed处理iPhone项目，并通过OpenGL着色器运行它以将效果应用于它。但是，每次我只是在代码中创建一个新的GLfloat时，调试器会在启动时冻结...我无法复制和粘贴文本，因为整个XCode都冻结了，但我已经从一个日志文件：

（gdb）
  

手机尚未冻结，因为我可以按主页按钮并继续做其他的东西。然而，Xcode 4已经完全冻结，运行在99％CPU的沙滩球，我必须强制退出并重新启动它。

然而...真奇怪的事情我有iPhone 3GS，当我借用某人的iPhone 4时，它会编译并运行正常。当我切换回iPhone 3GS时，仅适用于第一次的时间......此后，它会再次冻结。

是这可能是我正在做的事情，还是另一个XCode 4错误？我想尝试将调试器切换到LLDB，但是这并没有出现在Scheme窗口的下拉列表中...即使Xcode用户指南指出GDB和LLDB都可用：

谢谢！

解决方案

尝试让终端打开，并在程序生成并开始运行时在FOREGROUND（在XCODE的顶部）。 b
$ b

另外，如果可能，请尝试下载xcode 4.1。这似乎解决了这个烦人的问题，并且我可以再次使用调试器！

This is a really weird bug...

I'm working on an iPhone project using the camera feed and running it through an OpenGL shader to apply effects to it. However, every time I simply create a new GLfloat in the code, the debugger freezes when launched... I can't copy and paste the text because the whole of XCode freezes up, but I've cobbled it together from one of the log files:

(gdb) 

The phone has not frozen, because I can hit the home button and carry on doing other stuff on it. However, Xcode 4 has completely frozen with a beachball running at 99% CPU, and I have to Force Quit and start it again.

However... The really strange thing is I have an iPhone 3GS, and when I borrow someone's iPhone 4 it compiles and runs fine. When I switch back to the iPhone 3GS, it's fine for the first time only... After that, it freezes constantly again.

Is this possibly something I am doing, or is it yet another XCode 4 bug? I wanted to try switching the debugger to LLDB, but that doesn't appear in my dropdown list in the Scheme window... Even though the Xcode User Guide states that both GDB and LLDB are available:

Thanks!

解决方案

Try to have terminal open, AND IN THE FOREGROUND (ON TOP OF XCODE) when the program builds and begins running.

Also, if possible, try downloading xcode 4.1. This seemed to fix this annoying problem for good, AND I can actually use the debugger again !
