startup failure

[wolvre]

Hi there,

When I tried the example shared_counter, maple always aborted with an OSError: No such file or directory. But if I ran the tool within a python debugger, it seems fine. Any hint for this issue?

Best,
P

Hi, can you post the stack trace?

[wolvre]

As follows:

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

Did you compile the examples?

[wolvre]

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.

[jieyu]

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?

[wolvre]

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

[jieyu]

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

[wolvre]

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.

[wolvre]

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.

[owl337]

I did use full paths. 2017-09-05 17:05 GMT+08:00 wolvre <notifications@github.com>:
