Have you deleted the k2 project and retry?

Please post screenshots describing the commands you have run?

[zaheera01]

ok..

AFter setting it to GCc and Cmake . directly i went to k2 and executed the "setup.py "

[csukuangfj]

As said before, you have to delete the k2 project and retry.

Please post all.screenshots, including the.one about how you.delete k2

Your first step is wrong. Remember to follow.the doc.exactly.
