如何在clang（或gcc）中解码C ++名称？

Question

I'm trying to write a quick-and-dirty demangler for clang. I've found a piece of code that uses abi::__cxa_demangle , but I can't figure out which header it requires. The obvious choice is ABI.h but:

demangle.cpp:2:10: fatal error: 'ABI.h' file not found
#include <ABI.h>
         ^

What do I need to use abi::__cxa_demangle ?

Answer 1

Include cxxabi.h . In Ubuntu 13 this header is in /usr/include/c++/4.x where x is minor gcc version.

Answer 2

包括cxxabi.h，但是对于Ubuntu上的clang，你需要安装包libc ++ abi-dev。
