Error : implicit declaration of function

[Ashu2k]

First of all thank you so much for the code. I need a little bit of your help now.
I am using Eclipse IDE (Mars) with windows to develop my project. I have included all the necessary files required for your project and made all the necessary change in makefile, user_main.c and user_config.h (otaupdate project). But I am getting this error when trying to build the project

I tried with SDK version 1.5 and 1.3 but i get the same error every time.
I use the same header file in my other projects "osapi.h" and it works fine.
I don't know where the problem exists. Any help would be appreciated
