I have resolved most of the errors i was getting but now i only have two errors which i can't resolve : Undefined Symbol: Fl_JPEG_Image::Fl_JPEG_Image(char const*) and Undefined Symbol: Fl_GIF_Image::Fl_GIF_Image(char const*). Does anyone know how to resolve this?

i have resolved all issues and errors using guidance from Gpt, it is so much more useful than google.
