OSError: [Errno 13] Permission denied

[Shaikhul Hadi]

Hi, 

I have installed sniper in my machine (OS: Ubuntu 20.04) , compiled sniper and it compiled fine.

But when I want to run any test, like test/fft, after simulation starts, It shows this error :

wait for some times and then terminate showing error message:

ERROR: Could not establish SIFT connection, aborting! Check benchmark-app*.log for errors

I'm root user, so I have no permission restriction. I tried both "sudo make run" and run this while logged in as root. Both cases, I got  same result. I also tried to run sniper within the docker, got same error too. Could any one suggest me how could I resolve this issue?

Thanks

When you get permission denied, it could be because the file is not executable. Use ls - l to list all the files in the test/fft folder. Then use chmod a+x file to edit the permissions to executable. It should work after that.
