如何使用gcc和行号信息获取C ++的堆栈跟踪？ [英] How to get a stack trace for C++ using gcc with line number information?

问题描述

我们在专有的 assert 类似的宏中使用堆栈跟踪来捕捉开发人员的错误 - 当发现错误时，会打印堆栈跟踪。

我发现gcc的对 backtrace（） / backtrace_symbols（）方法不足：

1. 名称已损坏


2. 无行信息
   

第一个问题可以通过 abi :: __ cxa_demangle < a>。

然而第二个问题更加困难。我发现替换backtrace_symbols（）。
这比gcc的backtrace_symbols（）好，因为它可以检索行号（如果使用-g编译），并且不需要使用-rdynamic编译。

任何提议？

PS

gdb可以打印传递给函数的参数。
可能已经太多要求：）

解决方案

不久前我回答了类似的问题。您应该查看方法＃4上的源代码，该代码还会打印行号和文件名。

We use stack traces in proprietary assert like macro to catch developer mistakes - when error is caught, stack trace is printed.

I find gcc's pair backtrace()/backtrace_symbols() methods insufficient:

1. Names are mangled
2. No line information

1st problem can be resolved by abi::__cxa_demangle.

However 2nd problem s more tough. I found replacement for backtrace_symbols(). This is better than gcc's backtrace_symbols(), since it can retrieve line numbers (if compiled with -g) and you don't need to compile with -rdynamic.

Hoverer the code is GNU licenced, so IMHO I can't use it in commercial code.

Any proposal?

P.S.

gdb is capable to print out arguments passed to functions. Probably it's already too much to ask for :)

解决方案

Not too long ago I answered a similar question. You should take a look at the source code available on method #4, which also prints line numbers and filenames.
