Hi, can you post the stack trace?

As follows:

Traceback (most recent call last):

Seems that you were trying to test a program, but the script failed to find the program binary.

Did you compile the examples?

Yes, I sure did. As I've mentioned earlier, the script can test the program well within a python debugger (pdb), except that it has to be run in the sudo mode. I was running it on Ubuntu 12.04.2 LTS with Linux 3.2.0-43-generic x86_64 and gcc 4.6.3.

I never encountered this before. Can you try to run the script in sudo mode as well?

Also, what's your python version? 2.7?

I did run the script in the sudo mode. The python version is 2.7.3.

Sorry, I cannot reproduce this problem on my machine. It would be great if you can dig it on your machine.

Many thanks for your effort! I just figured out that it is because I was using a path abbreviation "~" for PIN_HOME in the script. I revised the script to load pdb. But in this version, I was using the full path. Apparently, the former does not work.

Would it be possible for me to get a copy of the source code of your case studies on splash2 programs (i.e., fft and radix)? This would help understand how to work with maple in details.

Hi, wolvre

I get the same problem as yours. But I don't make the problem clear. Could you give more details? My issue trace is as follows.

Thanks.

Sorry that I don't recall much details on this problem. My earlier comment suggests to use full paths for the environment variables, e.g., PIN_HOME. Hope this can solve the problem.
