我在Xcode中为OS X建立了一个大型的C / C ++ / Objective-C项目。该项目链接到预先构建的Qt5库。
这一切都很好用，直到崩溃并且我得到一个带有Qt函数的堆栈跟踪。如果我点击其中一个Qt函数的堆栈框架，Xcode / lldb显示汇编而不是源 - 我使用Qt作为外部库，所以我没有任何Qt源代码项目。我怎样才能解决这个问题？
我尝试将Qt5源添加到项目中而不将其添加到我的可执行目标中，但是Xcode / lldb仍然没有看到＆＃39;＆＃39;源或计算出我添加到项目中的源文件与Qt调试符号中引用的源文件相同。
如何告诉Xcode / lldb在哪里找到我正在使用的外部库的来源？
编辑：
在这里添加更多细节，当我输入＆＃39;目标模块查找-t QMenuBar＆＃39;在Xcode / lldb控制台中，这就是我所看到的：

显然，我的可执行文件中包含某种符号。它说这个定义来自qmenubar.h。我的硬盘上有qmenubar.h - 如何告诉Xcode / lldb在哪里找到它？
在Windows的Visual Studio中，如果我单击堆栈跟踪中没有Visual Studio可以轻松找到的源的框架，VS会弹出一个窗口，要求我浏览源文件 - 从那时起在，Visual Studio似乎直觉来源的其余部分基于您浏览的源的位置。例如，如果我有一个带有QMenuBar :: focusInEvent（）的堆栈跟踪，并且我点击它，Visual Studio会问我qmenubar.cpp在哪里。我可以浏览到C：\ Users \ ted \ Downloads \ qt5-everywhere-src-5.3.2 \ qtcore \ src \ qmenubar.cpp（或者无论它在哪里），然后Visual Studio假定其他来源可能位于附近。< / p>
这如何与Xcode一起使用？

我想我已经找到了问题的答案，但实际上只会引出更多问题。见Xcode equivalent of Visual Studio's "Find Source"。
我认为也许我的程序或我的Qt 的构建没有符号，或者没有必要的符号。特别是，在这个链接的SO问题中target modules lookup --address <address> --verbose（image是target modules的lldb同义词）的输出：

的Ack！哪里有源文件（CompileUnit）参考？感谢@vsoftco的建议以及其他任何看过这个问题的人。我将不得不深入研究Qt5构建系统并找出这些符号的位置。
