[SOLVED] gcc-12/13: std::stacktrace is still not found

Issue

I have this code:

#include <stacktrace>
#include <iostream>

int nested_func(int c)
{
    std::cout << std::stacktrace::current() << '\n';
    return c + 1;
}

int func(int b)
{
    return nested_func(b + 1);
}
 
int main()
{
    std::cout << func(777);
}

I install gcc-12 and gcc-13 by following on ubuntu22.04

sudo apt install gcc-13 g++-13
sudo apt install gcc-12 g++-12

Then I try to compile the code:

g++-13 -std=c++23 -lstdc++_libbacktrace test.cpp

Yet I get following error for both gcc-12 and gcc-13

test.cpp: In function ‘int nested_func(int)’:
test.cpp:6:23: error: ‘std::stacktrace’ has not been declared
    6 |     std::cout << std::stacktrace::current() << '\n';
      |

Solution

As in the comments, this is probably because your distribution does not fully support c++23 yet. Thus, the _GLIBCXX_HAVE_STACKTRACE checked in the header <stacktrace> is not set.
