iPhone 开发者 : Xcode debugger does not stop on breakpoints

标签 iphone xcode cocoa-touch debugging xcode3.1

我在 OS X 10.5.5 上安装了 Xcode 3.1.2。我有一个 iPhone 项目，可以正常构建，但调试器不会命中我设置的任何断点。我已经尝试了在网上找到的所有标准修复:

  1. 我已在 Xcode 偏好设置中关闭“延迟加载符号”
  2. 我的事件配置是调试
  3. build设置中的优化级别为 0
  4. 我已清理并重建了所有目标
  5. 我使用“构建和调试”(而不是“构建和运行”)

我认为我可能无意中调整了项目的设置。所以我创建了一个新项目，该项目也有同样的问题。

我希望我在这里错过了一些简单的事情。我的调试器几天前还在工作，但突然停止了。

<小时/>

更新:

事情正变得越来越奇怪。以下是对回复的一些回答

  1. 我在任何地方都找不到“GCC 4.0 - 代码生成”选项。我在“目标”和“可执行信息”页面上都看过了。我看到的唯一选项是选择编译器版本，并选择了 GCC 4.0，但这是一行部分，没有其他选项。
  2. 关于在哪里放置断点:我目前唯一的断点在 main() 中，并且没有被击中
  3. 我正在使用“运行”->“调试”(/% Y) 命令启动调试器。还是没有运气
<小时/>

更新 2:

  1. 将目标设置中的 Base SDK 更改为 Sim 2.2.1。将 Active SDK 更改为 Sim 2.2.1。
  2. 现在我可以看到 GCC 4.0 代码生成选项 - 调试符号已选中
  3. 仍然没有达到断点

这里是控制台日志(断点设置在 main.m 的第一行):

<- (gdb)

最佳答案

I cannot find 'GCC 4.0 - Code Generation' options anywhere. I've looked hi and low in both Target and Executable Info pages. The only option I see is to select the compiler version, and GCC 4.0 is selected, but that is a one-line section with no additional options.

如果 Active SDK 与目标的 Base SDK 不同步，则这是 3.1.1 和 3.1.2 中的 Xcode 错误。将 Target 的 Base SDK 设置为 Simulator，确保您的 Active SDK 为 Simulator，然后重试。

如果您确实想要回答这个问题，则必须发布有关您的项目的更多信息:build设置的屏幕截图或来自调试器控制台的文本。

更新: 另请注意 Xcode > 首选项 > 调试: alt text http://idisk.mac.com/cdespinosa/Public/GDB%20Log.png

选中该框，在路径字段中输入合理的路径，尝试您的调试方案，然后在http://bugreporter.apple.com处提交错误附上日志和对您的情况的描述，或者通过 xcode-users@lists.apple.com 询问好人。 gdb 日志包含有关调试器如何与应用程序交互的所有信息。
