Qt Breakpad 结果

Question

我正在关注此 url

中的注释

我在我的代码中编译了它（Qt，windows，VS 2015）我运行它处于调试模式，当它崩溃时我执行以下操作：

创建符号文件

dump_syms.exe ZendeskClient.exe > ZendeskClient.sym

使用dmp和符号文件生成文本文件（每一个都试过了）

minidump_stackwalk.exe filename.dmp symbols > ZendeskClient.txt 2>&1
minidump_stackwalk.exe filename.dmp ZendeskClient.sym > ZendeskClient1.txt 2>&1
minidump_stackwalk.exe filename.dmp ZendeskClient.sym symbols > ZendeskClient2.txt 2>&1

但我没有看到任何显示导致应用程序崩溃的原因。我在文本中看到（600 行）（它不是所有信息，只是希望足以显示我要显示的内容。其余数据有些相同）：

我构建输出的方式有问题吗？我在 windows 顺便说一句

Answer 1

Windows 上的调试实践的答案是通用的。当您 compile/link 您的项目时，Microsoft Visual C++ 构建工具会生成 Program Database File 格式的输出。然后当程序崩溃时，您会得到 .dmp 或小型转储文件，您可以使用特定的函数名称/行展开堆栈。

如何进行具有转储文件的实际调试？您可以将此答案作为 Wiki 使用 dmp 和 pdb 文件进行调试：Analyzing Crash dumps in Visual Studio。只需用 Visual Studio 打开转储文件，然后指向程序数据库，然后指向源代码，您将在崩溃时看到所有 threads/stacks 的图片。

更新：我们也可以 'symbolicate' 'empty' 没有名字的转储如回答：stackwalker loads all symbol files, but still doesn't symbolicate anything. I guess that the tool name is minidump_stackwalk.
