Hi. It's been a long time ago since I wrote and compile this code. It'd be for sure a way for ignoring these errors/warnings and compiling the whole source code. Unfortunately, I do not have any plan to update this repository but if you feel like contributing to my project and solving these issues you are more than welcome.
