Solution 1

Your are building for Win RT target. These functions arent available for that platform.

Check the project settings and the libraries...

What do you mean by Win RT target. Still getting the same linker errors. Is there are any
procedures to work on Win RT issue in VS2012.

Check the platfrom tool set in the project settings.

Are you building an Windows 8 App?

We are building in VC++2012. So we have now VC++2012.
This Error is displayed when migrating from VC++2008 to VC++2012.

you should carefully check the project settings. Somehow your settings will build a Windows 8 App.

And that doesnt work. Or you remove the functions calls which are the problems: always the first call of the linker errors.
