 Posted: Thu Aug 28, 2008 7:29 am Post subject: Attaching a running process |
 |
|
Hi,
I'm having difficulties when I try to attach a running process in Ubuntu. I've set the "Build result" to point to my executable, but when ever I try to attach the debugger I get "The executable with the selected project does not match the selected processID". What am I doing wrong?
Cheers,
Kristofer |

I can't say without more information. Can you look in /tmp (possibly
/var/tmp) for
the most recent gdb-cmds*.log file (immediately after trying to attach)?
Verify the
time and date match the attempt you just made.
If the failure is before gdb is started, there won't be a log showing
the failure. If
this is the case, try running "netbeans -J-Dgdb.logger.level=FINE" and
send me
the messages.log file from your userdir (default is
~/.netbeans/<NB-version>/var/log/messages).
It would also help if you said what version of NetBeans you're running.
By the way,
when you selected the process, did you also select the matching project
at the bottom
of the attach panel? You need this because gdb requires sources to debug
and the only
way to tell netbeans' gdb module where they are is from the selected
project.
Thanks,
Gordon

The C/C++ project is created from existing source, so the code is not in the "workingDirectory". Could this be an issue?
Also, I did make sure that the correct project was selected in the drop-down list.

I'm still having issues with this? I need help to understand what I'm doing wrong if this indeed isn't a bug. You may call me fool or stupid if it helps.

You're providing so little information that it is difficult to help. For
sure there is no known bug like what you see.

Alright! I thought I had provided the information that was asked for. What else do I need to supply?

You meant this:

I think you should file a bug against cnd/gdb and then the assigned
engineer will ask more specific questions (if any).

Update: If I don't set the "Run Directory"-property and at the same time don't forget to set the "Build result directory"-property it would appear I'm able to attach running processes. |

I found the root problem on this topic.
If the path in the settings contains any symbolic link path, Nebeans is unable to attach the process. I mean when '/bin/pwd' doesn't match 'echo $PWD'. To avoid the problem, the path must be set based on the path returned from '/bin/pwd'. Otherwise, Netbeans fails to attach, even on Nebeans 6.7. |

Can you please file a bug with the testcase,
I'm sure it can be fixed quickly.
Thanks,
Egor
