So, did you even go so far as to search google using these messages, or even the first one? You reported this problem two weeks ago, various suggestions and diagnostic avenues have been suggested, most of which you seem to have ignored. Your code provided is essentially a copy/paste from this SO post, with an additional button on the GUI, which includes one solution (already suggested here). If explicitly linking a library ensure they actually exist at the path you provide.

If you want to use tool to successfully achieve a goal you need to learn how they work and how to use them. If people make suggestions it's usually not for their own good. If someone suggests various things to try, try them all before replying

The example works properly with the pp call provided under Windows 7 with Strawberry Perl.
