How to modify makefile by calling FPGA and GPU?

Using the example "vector-add" given by the cloud platform, I simply added "queue q1(default_selector, exception_handler);", to get an FPGA and a GPU at the same time using" queue q(d_selector, exception_handler);
queue q1(default_selector, exception_handler);", what commands should be used when compiling? Here is my Makefile.fpga, with the output error information.

"dpcpp -O2 -g -std=c++17 src/vector-add-buffers.cpp -o vector-add-buffers.fpga_emu

Makefile.fpga:19: recipe for target 'vector-add-buffers.fpga_emu' failed ".

So how do I modify makefile. Command in FPGA?Please understand the friends give some advice.

Hi ,

Can you share the complete source file and make file which you have changed.

Thanks and Regards
