Add the following library to the linker input files:
VS 2015 now uses inline definitions that call internal functions for many of the stdio.h functions. If an object file (or library member) depends on one of those functions, then the legacy_stdio_definitions.lib provides an externally linkable version of the function that can be linked to.
Your other option is to recompile the unit that depends on those functions with VS 2015 (this is probably the preferred option).
I have resolved it.Thanks
