How can we possibly be expected to deduce what might be the source of
the OP's problem, when we aren't shown:

  - the exact command used to compile
  - any error messages produced by the compiler?

All we've be shown so far, is a chunk of (incomplete) source code, and
we've been asked if we might try to compile it; since it is incomplete,
we can't even begin to do so, but I would question this:

>>> #include <C:\mingw\bin\Gnomonic.hpp>
>>> #include <C:\mingw\bin\Geodesic.hpp>

That's just wrong!  The angle brackets tell GCC to search the system
include paths for the headers, but they aren't there; they are in the
absolute path C:\mingw\bin, but since that path doesn't begin with a
"/", GCC may not even recognize it as an absolute path, so will affix
system path prefixes, until it exhausts all possibilities, without
finding them.

What I suspect is intended, is that these headers are in the same
directory as the program which includes them, so correct syntax would be:

   #include "gnomonic.hpp"
   #include "geodesic.hpp"

and for $DEITY's sake:

  - stop using C:\MinGW\bin as a working directory;
  - get out of the habit of using mixed case file names for
    program code; (it may not matter on Windows, but it is
    sure to bite, if cross-compiling on a case-sensitive
    platform);
  - if your header references _must_ include directory name
    separators, get into the habit of using the "/", as
    $DEITY intended, in preference to the "\" favoured by
    the demons of Redmond.
