Help running valgrind

I’m having some trouble runnign valgrind on root. When I run it, I get basically nothing back - which I have trouble believing… :slight_smile:

[code]bash-3.2$ valgrind --leak-check=full root -q

This was a debug build (I did the build)… W/out the suppression file there is no way it was that clean. And even if I do more, I still see a report almost as clean. So - is it really this clean? Or am I running this incorrectly? :slight_smile: -GOrdon.

you must run on root.exe, not root. see Users Guide


Ah! Thanksm Rene. I didn’t think to look in the users guide for something like this, and on Linux, it didn’t occur to me that a .exe would exist (nor does it show up in the process list). Have created a script to do this so I don’t forget next time. Should help me with my other problems!
