    I finally found the solution. The answer is : compiling c++ code in fpga mode with i++ compiler needs a huge amount of Ram and hdd resource for page filing. For example a cycloneV design needs about 64gb ram and resource. it depends on your design. That is it.

Hi @Engineer87,


Thank you for the hold, we have managed to try and compile the code provided and it compile successfully for emulator mode. (with some minor error where main.cpp include image.h instead of Image.h)

Hence there are still posibilities that it is environment or code might be the issues. So perhaps would suggest to check on the below:

- did you managed to compile the design emulator flow and successfully completed?

- did you managed to compile other more simple design from the example?

- based on the error logs there seems to be connection to math.h, however did not see it part of the import, may i know what is the connection there?


Best Wishes

BB

Hello and thnx for your answering. Fyi the design is ok with x86 architecture in i++ compiler and make .exe file correctly but in fpga mode does not work and had error as mentioned. And for your second note i should say yes i try and successfuly compiled and program cyclonev chip with counter.cpp and image down.cpp example so i think my program version is ok . but in your third sentense you said math.h , i appreciatd that you spread it more for me... about log and what you saw in it about math.h and what should i do? Thank you for your attention and i wait for your answer. I saw other topic problem like command line is too long, and i did not found any useful solution for it. Fyi :

Please check it. I am still waiting for your solutions.

Best regards.
