如何最好地确定二进制文件是否包含STAB或DWARF调试信息? [英] How do I best determine if a binary contains STAB or DWARF debug information?

问题描述

当涉及到ELF时，两种随附的调试格式在其他格式中极为流行，即 STAB和DWARF .我想要一种简单的方法来确定给定的二进制文件是否包含一种形式或另一种形式的调试信息，最好不必检查节名称(.stab等).

When it comes to ELF, two accompanying debugging formats are overwhelmingly popular to others, namely STAB and DWARF. I'd like an easy way to ascertain whether a given binary contains debug information of one form or the other, preferably without having to inspect section names (.stab, etc.).

有什么好的方法可以做到这一点?

推荐答案

当涉及到ELF时，两种伴随的调试格式非常流行

When it comes to ELF, two accompanying debugging formats are overwhelmingly popular

在过去10年中，ELF平台上的任何当前编译器均未默认使用STABS格式.绝对不是压倒性的流行".

The STABS format has not been used by default by any current compilers on ELF platforms for the last 10 years. It's definitely not "overwhelmingly popular".

告诉方式:

readelf -WS ./a.out | egrep '\.(stab |debug)'

如果二进制文件具有STABS，您将看到.stab部分.如果您具有DWARF，则将看到.debug_info，.debug_line等.如果根本没有调试信息，您将什么也看不到.

You will see .stab section if the binary has STABS. You will see .debug_info, .debug_line, etc. if you have DWARF. You'll see nothing if you don't have debug info at all.

最好不必检查部分名称

preferably without having to inspect section names

如果不查看部分内容就无法完成:正是这些部分的存在或不存在使二进制文件包含或不包含调试信息.

Can't be done without looking at sections: it's the presence or absence of these sections that makes the binary contain or not contain debug info.
