I am trying to build package/app/utility which has to use kernel header (for gpio ) and library headers.

Your build environment is referring to both the (wrong) include files in your toolchain's staging directory and to the (right) include files under your target directory.

The reason why this happens is unclear from your post, though. If you have attempted the ordinary "make distclean" etc. solutions, then perhaps the GNU make makefile that you use to build your application, or the OWRT package's "makefile" may yield some clues as to why this is happening? Have you checked the include directories?

The discussion might have continued from here.
