Hi,
Based on my understanding, you are using the command eg:i++ stream_test.cpp -v -march=x86-64 -o test-x86-64 or make test-x86-64, am I right?
If yes, this command is used to compile the C++ source
code to an x86-64 binary executable and run the generated executable on your
CPU.
You could able to use command eg: make test-fpga or i++ -march=Arria10 stream_test.cpp -o test-fpga
to have a .prj directory and you could able to find a .qpf file to open in Quartus Prime software.
Beside, I could not able to compile the file with error: 'utils.hpp' file not found. Could you try to attached the full design file?
Thanks
