linux - 如何显示包含在C/C++共享库中的头文件和src文件的名称

Question

对于C/C++共享库(.so文件)，如何查看其中包含的所有头文件和源文件的名称？

我尝试使用 -g 选项编译共享库，并使用 readelf -Wl，但我只能得到如下内容:

Answer 1

你的 .so 甚至不一定有任何这些信息，除非它是用“-G”显式编译的。

建议:

• How can I know what type of debug info is in an ELF object file?

  objdump -g

  objdump -W file.elf

• How do I best determine if a binary contains STAB or DWARF debug information?

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

• Debugging formats DWARF and STAB
