program giving a compile time error

Diksha28 (3)
I am trying to calculate the sum of the series below (line 3). This is what I've come up with. I tried compiling and running it but there is a compile time error "[Error] ld returned 1 exit status". I'm unable to figure out why. Can anybody please help me? Thanks in advance.

This is my code:

/* FUNCTION TO PERFORM THE SUM OF THE FOLLOWING SERIES

Well, it works fine on both cpp.sh and Code::Blocks IDE, it even gives the right answer. The problem is definitely not in the code.
