Valgrind permission denied on file

Question

I am running Ubuntu 12.04 and installed Valgrind configure and installed it. Everytime i run valgrind ./ file I always get permission denied even under root.

Answer 1

turn on the executable bit and then retry:

chmod a+x ./file

it is a safety feature to disallow executing just about any file by default. and be very careful with unknown files in your root account.
