Hi,

I get the following error when profile with debugging  as root(use sudo).

How to setup and generate the correct file for it?

syscall failed: No such file or directory
error opening /tmp/901059da-2b0a-44dd-b5e8-0de4e58dcb93-shared-mem-vgdb-80885-by-root-on-??? shared memory file

No problem. Please let us know the email address associated with your license so that we could link it to your support profile.

I am still using trial verison since last week,  I will purchase one  before the trial ends and some problem is solved.

Hi,

This looks like an incompatibility between valgrind and your kernel and not something directly caused by VisualGDB.

As far as our support goes, we can explain how VisualGDB launches valgrind and what modes it uses, however we would require an active license for that.

According to our records, we have replied to your inquiry with the details on the academic license purchase.

Hi,

Thanks, we have linked your key to your profile. Regarding this error, please try enabling View->Other Windows->VisualGDB Diagnostics Console and starting a profiling session without debugging.

If it still doesn’t work, please take a note of the valgrind command line shown in the VisualGDB diagnostics console. It will show the path to the profiled program and some other arguments.

Please then try manually running valgrind with that program without any other options, e.g.

valgrind /tmp/my-program

Does valgrind work when launched manually? If yes, please post the exact command line you captured from VisualGDB Diagnostics Console and the exact command that worked manually.
