Does main.cpp #include AboutDialog.h? If so, does AboutDialog.h define
such functions (note, not just functions with the same name, but
taking the type and number of arguments you've supplied in the
function call in main())? If so are you linking the files correctly -
see your compiler documentation for more info on that.
Hope this helps,
Matt.
