I'm trying to use SystemTap.
I followed the instructions here:
http://sourceware.org/systemtap/wiki/SystemTapWithSelfBuiltKernel
I built the kernel with these options:
Kernel hacking --->
[*] Kernel debugging
[*] Compile the kernel with debug info
Instrumentation Support --->
[*] Kprobes (EXPERIMENTAL)
And also, with CONFIG_RELAY, despite the documentation says it's optional.
General setup --->
[*] Kernel->user space relay support (formerly relayfs)
I'll update the website. relayfs is no longer optional.
From the error messages, it seems like you have a kernel with
CONFIG_DEBUG_FS disabled. It should be included by default in new
kernels. I'll add in a specific check for that. Could you check if that
is the problem.
