Most usefully it would live in file like drawWindow.cpp which then should compile into drawWindow.o and should then be added to the linker line above. What's about toolkitWindow.o ? Anyway as I assume from the layout of your errors, drawWindow is a locally defined object, which should live somewhere near your code. Or should it be in some library ? You may just have forgotten object file or libary. Try to find out which.
