Hi there. jpeglib is a little bit butterfingers. Its headers have no=20
checking for c++ environment. You got to know, that jpeglib is a C library,=
=20
and thus, you should include them inside an extern "C" block. Just like=
 this:

extern "C" {
#include "jpeglib.h"
}

The header also doesn't really want to run together with some standard C++=
=20
includes and tries to redefine Types and stuff. Maybe it will be fixed=20
someday...
