boost堆栈跟踪不显示函数名和行号

我在探索 boost::stacktrace 通过尝试一个简单的例子来打印递归函数的调用堆栈。

#include "boost/stacktrace.hpp"

int factorial(int x){
    if (x < 2) {
        std::cout << boost::stacktrace::stacktrace();
        return 1;
    }
    return x * factorial(x - 1);
}

int main(int ac, char *av[]) {
    std::cout << factorial(4);
}

但是,代码的输出不包括有关函数名和行号的任何信息:

 0# 0x000055A6F6B57C0F in /home/user/myapp
 1# 0x000055A6F6B57C42 in /home/user/myapp
 2# 0x000055A6F6B57C42 in /home/user/myapp
 3# 0x000055A6F6B57C42 in /home/user/myapp
 4# 0x000055A6F6B57C9D in /home/user/myapp
 5# __libc_start_main in /lib/x86_64-linux-gnu/libc.so.6
 6# 0x000055A6F6B57AEA in /home/user/myapp

这与boost网站的示例输出相反: (抄送自 https://www.boost.org/doc/libs/1_68_0/doc/html/stacktrace/getting_started.html#stacktrace.getting_started.how_to_print_current_call_stack )

0# bar(int) at /path/to/source/file.cpp:70
1# bar(int) at /path/to/source/file.cpp:70
2# bar(int) at /path/to/source/file.cpp:70
3# bar(int) at /path/to/source/file.cpp:70
4# main at /path/to/main.cpp:93
5# __libc_start_main in /lib/x86_64-linux-gnu/libc.so.6
6# _start

为什么在堆栈跟踪输出中看不到源行号和函数名?

我已在项目级别启用调试信息 CMakeList.txt :

set(CMAKE_BUILD_TYPE Debug)

我还可以看到在请求二进制文件时出现的符号:

nm -an myapp | c++filt | grep factorial

0000000000000f40 t _GLOBAL__sub_I__Z9factoriali
00000000000010f0 T factorial(int)
