It was a big difficulty: I've been developing and maintaining this codebase since Y2K, and to make it portable on different OSes (Linux, Mac, Windows, Emscripten, Android), we often had to "reinvent the wheel". At the very beginning in the 90's, we did not even have std::string ! As time passes, I can get rid of some code. For instance, FileSystem will be replaced by std::filesystem, spinlocks with std::atomic (if they are as efficient) and so on and so forth... I'd be interested to know what is a true "showstopper" for you, do not hesitate to post issues here: https://github.com/BrunoLevy/geogram/issues https://github.com/BrunoLevy/geogram/issues
