HELP! gcc multiple errors related to libraries

Everything was going well until this morning when I tried to build my project and.. well this happened.. anyone knows what the hell is this, and how can I fix this??
there were many more errors but i took these 4 random prints, if you need more to get this please just say it.

Thank you.
