I have problem which was mentioned here multiple times, but i still cant find out how to relsove it.

I want use ceil() function in NetBeans-IDE, but still getting error Undefined reference to 'ceil'. I tried add -lm into gcc compiler by project properties but no success.

Can someone help me how to solve this specific problem?

I tried code from that post, but still getting the same error – user1827257 Oct 29 '16 at 12:40
Where is `-lm` in the link line? Before or after the object file that references `ceil()`? You've not shown the linking command line, but if `-lm` occurs too soon, it may as well not be there. – Jonathan Leffler Oct 29 '16 at 18:28
