undefined reference to 'function' in Xilinx Eclipse SDK - c

Question

I am confronting
undefined-reference to 'function'
in my C code using Xilinx Eclipse SDK. However, the functions is already built !
In fact, I found a [solved] similar issue, but I couldn't reflect the solution to my case.
this my console output:
