Hello All,

I am trying to run Valgrind on FreeBSD. I am getting the error about 
ksem_open which i stated below. I have searched for  a solution to be 
able to solve this problem and found the calgrind patch. I could not 
found the instructions to apply this patch. How can i use valgrind on 
FreeBSD with ksem_open enabled?

Kind Regards
Resit Sahin

I use valgrind version:  valgrind-3.6.0
FreeBSD Version :FreeBSD 8.1-RELEASE-p2 FreeBSD 8.1-RELEASE-p2 #6:  amd64

The error i get : (The valgrind output)
