    undefined reference to `sscanf'

    greblys

      I am trying to build my App for BCM920737 using Wiced SDK and for some reason I am getting undefined reference to sscanf error even "stdio.h" is included at the top of source code. Strange that I do not have problems with sprintf() function which is located in the same library. I understand that this problem occurs when object files are linked together, so maybe I need to do something smart in my makefile? Are there any documentation or explanations about makefiles used in Wiced SDK? I am using WICED Smart 2.2 on Ubuntu 14.04.

       

      Makefile contents:
