Cannot find -liostream

[Yoooooo]

Hello. My codeblocks hasn't worked since I turned on the PC today.The compiler literally can't find the iostream library and I don't know why. I gave it the right extension: .cpp when using c++ language.
This is the build log that showed up after rebuild:

Cleaned "ehusosoenflsfmsdk - Debug"

I use GNU GCC compiler , my current codeblocks version is 16.01. The thing is that I had a couple of moments ago the 10.05 version of codeblocks and I was given the same error. But i uninstalled it and I installed the current version, but it keeps returning that error. I installed the codeblocks from here: http://www.codeblocks.org/downloads/26#windows , choosing the forth option from the Windows XP/Vista etc section. I have windows 8.1 by the way. What could be the cause? Thank you very much!

EDIT: SOLVED BY ME, I'M A GENIUS
