附加到远程进程进行调试 [英] Attaching to a remote process for debugging

问题描述

在OSX 10.5上使用Xcode 3.1;是否可以将（调试器）附加到正在运行的远程进程？

我知道可以启动和调试远程进程（如 here ），但是如果我可以找到一种方法来附加到已经运行的远程进程，那将是很好的...

编辑添加：谢谢。我向苹果提交了一个错误报告。如果/当我听到他们的话，会更新这个问题。

解决方案

在XCode中没有很好的gui，但是你可以这样做：

1. 通过远程调试从XCode启动程序的第二个实例，


2. 使用控制台中的GDB attach命令

分步说明：

1. 按照Apple的说明设置远程调试：




2. 找出您的程序运行实例的远程框中的：

   
   
   

   sshremotemachine'ps -x -w -w' grepAppName

   
   
   

   （您也可以使用ARD和ActivityMonitor）




3. 将断点您的应用程序主机，并从调试器（在远程框上）启动第二个实例




4. 在GDB控制台（运行/控制台菜单）中输入： p>
   
   

   附加 process-id




5. 现在你有XCode附加到运行过程。您现在可以使用图形调试器。

（在早期的XCode中，没有GUI附加到本地进程，所以 this技巧/黑客是解决方案... ）

Using Xcode 3.1 on OSX 10.5; is it possible to attach (the debugger) to a running remote process?

I know that it's possible to start and debug a remote process (as explained here), but it would be great if I could find a way to attach to an already running remote process...

edit to add: Thanks. I've submitted a bug report to Apple. Will update this question if/when I hear back from them.

解决方案

There is no nice gui for it in XCode but you can do it this way:

1. start a second instance of the program from XCode with remote debugging,
2. use the GDB attach command from the console

Step by step instructions:

1. Follow Apple's instructions to set up remote debuging:

2. Find out the process-id of the running instance of your program on the remote box:

   ssh "remotemachine" 'ps -x -w -w' | grep "AppName"

   (you can also use ARD and ActivityMonitor)

3. Put a breakpoint to your app main, and start a second instance from the Debugger (on the remote box)

4. In the GDB console (Run/Console menu) enter:

   attach process-id

5. Now you have you XCode attached to the running process. You can now use the graphical debugger.

(In early XCode, there was no GUI for attaching to local processes, so this trick/hack was the solution...)
