Yeah,

I just created it myself as told in initial posting. I thought it was a directory needed by the pipe.

Judging from Nate's suggestion i need to install an executable there. Will update thread, when I do.

Thanks,

Nikos

Hi Nate,

I imagine you refer to baudline.py which is in the error trace.

baudline: command not found

For baudline.py to run, I would have to have /usr/local/lib/python2.7/... part of my PATH, which i don't.

/opt/AMDAPPSDK-3.0:/opt/AMD/CodeXL:/home/nikos/bin:/home/nikos/baudline_1.08_linux_x86_64:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:.

Is this smt i should add to my PATH?

BR,

You have nothing in your baudline directory, other than the usual "." and ".." housekeeping links.

Hi Nikos,

Does baudline start if you just run the command "baudline" from the terminal?

Can you send the output of this command:

ls -al /home/nikos/baudline_1.08_linux_x86_64 ​
