I'm trying out CodeAnalyst on Redhat Enterprise Linux WS release 4 on a 4 CPU Opteron (Each CPU is a Dual-Core AMD Opetorn processor 2218). I've installed (or so I think) everything correctly, but when I try running Codeanalyst on an application I get the following error
"Oprofile daemon failed to start
Reason: Cannot open /dev/oprofile/buffer_size.
Please check if:
1. The file exists
2. User in in "amdca" group".
From what I can see
- Oprofile sampling driver is loaded (from "codeanalyst_init status")
- The file /dev/oprofile/buffer_size exists and is readable
- I am in group amdca
I've restarted codeanalyst, but get the same error.
What else do I need to check/fix?
