Compiling and linking two opencl files

Hi,

   I wrote kernels which are distributed between two files. And I tried compiling , it looked to be compiling fine.

But during linking it throws error as below.

I am also attaching my Makefile for reference.

Please let me know how i can solve this error.

 make
aoc -v -report -march=emulator -legacy-emulator -I ../../stb -I device/RTL -L device/RTL -l rtl_lib.aoclib  -g ./device/conv_pipe.cl ./device/frcnn.cl
