Ah, it seems the issue isn't with the compiler itself, but rather with the default C++ standard, which is set to 17 on my system running Ubuntu 22 here is the edited CMakeList.txt which work fine |

Interesting! A more backwards compatible approach would be to use the spaceship operator instead of implementing specific ones like we do now. I believe that would make it work on C++17 too. See #509 |

Hmm, and one more thing: the contains method for maps is not available for the standard version less than 20. So, I'm also encountering an error for that |

Yep. The documentation (https://jsontoolkit.sourcemeta.com/) clarifies that C++20 or later is expected. Probably a lot more would be needed to make it work on C++17 which is likely not worth it |
