I don't know, but then I don't see why it shouldn't compile for you. You didn't show any error messages, so it's hard to tell. > Would this even work on my computer?

Yes, it will work, assuming that Gnomonic and Geodesic don't have their code in a library, only in the 2 .hpp files. > Is there a manual of the compile (in Win / DOS command wiondow)?

So it's hard to try to do anything with this code.
