Callgraph help (Error - Internal error while resolving the results file)

[Deleted_U_Intel]

Hi,

I'm trying to use callgraph collector on my linux machine.

This is the command I issue:

vtl activity test_1 -c callgraph -app tester -moi tester run

(tester is a very simple application written in C)

Vtl returns after some time, but it reports an error, and there are no results collected.

I get these messages after hitting enter:

Any help is appreciated!

(Sampling collector works fine.)

Thanks.

try running a callgraph on /bin/ls

same error?

Hi,

I had the same error. When I run:

$ vtl activity -c callgraph -app /home/akshan/code/a.out -moi /home/akshan/code/a.out run

Where a.out was compiled with gcc options "-g -O0"
After seeing this thread, I tried:


$ vtl activity -c callgraph -app /bin/ls -moi /bin/ls run

And I was able to "vtl view" the results. Any suggestion as to what I'm/we're doing wrong in the first case?

Your advice is greatly appreciated.

Hi,

Sorry to reply to my own post. But I read around some. I configured the callgraph configuration '.ini' file, setting the instrumentation level to 'Minimal' for my module. It worked. Of course it had no information in it.

My application "a.out" is a very basic, one file C program. All it does is invoke a function(defined in the same file) and exits with a exit value determined by the retval of the function. It was compiled with "gcc -g"

The activity command was:

$ vtl activity -c callgraph -app /home/akshan/code/a.out -moi /home/akshan/code/a.out run

My platform is:

a Xeon 64-bit,Red Hat Enterprise Linux 4.0 (Kernel 2.6.9-5.EL)

`uname -a`
Linux localhost 2.6.9-5.ELsmp #1 SMP Wed Jan 5 19:30:39 EST 2005 i686 i686 i386 GNU/Linux


I'm including the environment seen by the call graph activity, in the attached file

Any suggestions?
Thanks,

Aravind.

Have you experimented with various aspects of the .ini file? That is, make all functions minimal, see if it works (you did this already). Leave all functions but one "minimal," see what happens? Add functions one at a time until you find out which one is causing the failure, which may give a clue about what is failing.

HOWEVER, you should feel free to open a premier case on this, at http://premier.intel.comso our support engineers can help you out.

ALSO: have you considered using the analyzer versions 8.0 instead of 3.0?

cheers

Hi Jdg,


I tried a Callgraph activity on a Fortran module compiled with ifort, and it worked.

Since that is my primary interest and since I'm coming up against some deadlines, I'm not going to pursue this further at this point.


Thank you,
Aravind.

Thanks for the update!

It's probably too late for this thread, but I had the same problem when running vtune in Eclipse. It was working without any problems and after a total system crash I got the error.

I fixed it by closing vtune (in my case I was running it in Eclipse using vtlec). I removed the vtune tmp directories in /tmp. I removed all directories and files used by vtune in my workarea directory.

i.e. Project directory, .project, vtwrkspc.vws, .metadata

I re-started vtlec, recreated a new Call Graph view, and it worked OK.
