    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
