You seam to have multiple Criticals and Warnings. Try to fix one by one.
The first seams to be that the overlay pointer hasn't been set (still NULL).
I would recommend you look into the code of a similar application of what
you are trying to do. Specially one which you can build and run in Windows,
so you confirm you have all the neccesary system libraries.
