Boost stack-trace not showing function names and line numbers

Question

I was exploring the boost::stacktrace by trying a simple example to print the call stack of a recursive function.

#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);
}

However the output of the code does not include any information about the function name and line number:

 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

This is in contrast with the sample output from the boost website: (copied from 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

Why don't I see the source line numbers and function names in the stack-trace output?

I have enabled debugging information in my project-level CMakeList.txt:

set(CMAKE_BUILD_TYPE Debug)

I can also see the symbols are present when demangling the binary file:

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

0000000000000f40 t _GLOBAL__sub_I__Z9factoriali
00000000000010f0 T factorial(int)

You need to do a few things (this is for Linux):

1. Make sure that debug info is enabled: e.g., -g

2. Link against libdl: -ldl

3. Define one of the necessary macros (to get line numbers): e.g., -DBOOST_STACKTRACE_USE_ADDR2LINE
