Gdb 在发布模式下分析应用程序的调试器输出

我使用Ubuntu12.10下的i686-w64-mingw32-GCC4.7.2交叉编译器开发了一个win32应用程序

当我运行在发布模式下编译的应用程序时，它崩溃了，我可能会收到如下输出

我想知道如何解释它？我能从中得到一些有用的信息吗？例如，可以从堆栈转储获取源代码中的行吗

Make sure that your X server is running and that $DISPLAY is set correctly.

我想知道如何解释它

看起来已经很清楚了：您的代码，更准确地说：地址

0x401cb1

处的指令试图解除地址

0x00006c11

处的内存引用。该内存访问无效，并触发了页面错误

我能从中得到一些有用的信息吗

是的，如上所述

例如，可以从堆栈转储获取源代码中的行吗

当然：在发布模式下构建应用程序时，添加

-g

标志。然后

addr2line -fe analyser 0x401cb1

---

应该告诉您地址

0x401cb1

对应的文件/行。

特别感谢您指出我不知道的addr2行。
