Undefined referance to 'vxAccessImagePatch' error while building code

I am writing custom kernel to copy data from one image to other image using OpenVX . I have used
vxAccessImagePatch() API to access data reom Image .

I have also included vx_compatiblity.h file at starting of my file . But implementation to vxAccessImagePatch is not discovered during Compilation

I am Currently building code using TI -PSDKRTOS SDK . Can Anybody explain why i am getting this error ?
