dpcc code for fpga emulation using jupyter notebooks

Question

I was performing emulation of hough transform for FPGA's on Jupyterlab but then all i had to do was run the cells:

I get the following error ->

u196294 is performing Hough Transform compilation emulation notebook.

icpx: warning: use of 'dpcpp' is deprecated and will be removed in a future release. Use 'icpx -fsycl' [-Wdeprecated] src/original/hough_transform.cpp:8:10: fatal error: 'CL/sycl/INTEL/fpga_extensions.hpp' file not found #include <CL/sycl/INTEL/fpga_extensions.hpp> //try this and prev ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1 error generated. /bin/bash: bin/hough_transform.emu: No such file or directory

I am not sure how to solve this. I am unable to find the header files that they are supposed to include. I cant even find the parent directory which is supposed to be 'CL'.

Has anyone done fpga emulation using jupyterLabs and gone through the same problem? i am eagerly looking for help, thanks

Please try to make the following changes in the code and it will work perfectly, try to ignore the warnings if you get any.

In the hough_transform.cpp please make the below changes -

1. In line 9 change from

   #include <CL/sycl/INTEL/fpga_extensions.hpp>

to

#include <sycl/ext/intel/fpga_extensions.hpp>

2. In line 72 change from

   sycl::INTEL::fpga_emulator_selector device_selector

to

sycl::ext::intel::fpga_emulator_selector device_selector

3. In line 76 change from

   sycl::INTEL::fpga_selector device_selector

to

sycl::ext::intel::fpga_selector device_selector

In hough_transform_kernel.hpp please make the below changes -

1. In line 9 change from

   #include <CL/sycl/INTEL/fpga_extensions.hpp>

to

#include <sycl/ext/intel/fpga_extensions.hpp>

2. In line 30 change from

   INTEL::fpga_emulator_selector device_selector

to

intel::fpga_emulator_selector device_selector

3. In line 32 change from

   INTEL::fpga_selector device_selector

to

intel::fpga_selector device_selector

And you are getting the error " cannot create directory 'bin': file exists " because there might be a directory named bin already present in that path.

You need to delete it and re-run the cells again and it should work without any errors like the screenshot given below.
