collect2.exe: error: ld returned 1 exit status

I am trying to build S function to perform SIL on my model. but I am getting an error for the function "Runnable_Step" which I am calling from "output" (Code description) section of S function. The error is as below :

C:\Users\105316~1\AppData\Local\Temp\mex_75352478274417_9204\S_Function_EVDC_wrapper.obj: In function `S_Function_EVDC_Outputs_wrapper': C:/Users/105316885/Documents/MATLAB/14JUN_SIL/S_Function_EVDC_wrapper.c:64: undefined reference to `Runnable_Step' collect2.exe: error: ld returned 1 exit status

Can anyone suggest any solution.
