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. -- Regards, Keith.
