Hi,
Thank you for posting in Intel communities.
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_selectorto
sycl::ext::intel::fpga_emulator_selector device_selector
3. In line 76 change from
sycl::INTEL::fpga_selector device_selectorto
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_selectorto
intel::fpga_emulator_selector device_selector3. In line 32 change from
INTEL::fpga_selector device_selectorto
intel::fpga_selector device_selector
In addition, you can run the command (i.e. mkdir bin) to make the directory bin and proceed with the compilation like I did in the below screenshot.
If you face any issue please connect back to us.
If this resolves your issue, make sure to accept this as a solution. This would help others with a similar issue. Thank you!

Thank you so much for your help diya, but now the jupyter doesn't recognize the dpcpp, as shown in code snippet below. it cannot even find icpx.
Thanks a lot, the first line,
source /opt/intel/oneapi/setvars.sh --forcehelped in setting the environment and i got the output
:: oneAPI environment initialized ::
but when i try to emulate i again get the error: /usr/bin/ld: cannot open output file bin/hough_transform.emu: No such file or directory, even though i created the bin directory, as can be seen in the attached pic
thank you,with your kind guidance, i have reached to the optimization stage,
Platform name: Intel(R) FPGA Emulation Platform for OpenCL(TM)
Device name: Intel(R) FPGA Emulation Device
Kernel execution time: 0.016045 seconds
VERIFICATION PASSED!!
The compile is finished.
but when i see reports.html in the
bin/unroll/hough_transform_split.prj/reports/report.html
nothing appears when i press trust html button, as shown in screenshot in the pic attached
although i can see the report_data.js file as below
after getting: Kernel execution time: 0.016045 seconds
VERIFICATION PASSED!!

The compile is finished.
then i followed the instruction in the file as shown in following screenshot:
therefore, when i searched the path bin/split/hough_transform_split.prj/reports/report.html, i found the files
report_data.js and many. According to FPGA_Optimization_Report_Generation_Using_Intel_oneAPI_Base_Toolkit.pdf file, for getting reports, i need to open report.html file and press trust HTML, and pressing is not giving any output.
Hi,
We tried to investigate the issue from our end and came up with a solution.
It seems like Jupyter has issues trying to load local HTML files even after pressing the "trust HTML" button.
https://github.com/jupyterlab/lumino/issues/240
So, please try to extract the "report.html" file from Jupyter and view it in a browser and you can view the reports.
If you face any issues, please connect back to us.
If this resolves your issue, make sure to accept this as a solution. This would help others with similar issue. Thank you!
