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.

Indeed I didn't have it enabled:


$ zgrep DEBUG_FS /proc/config.gz
# CONFIG_DEBUG_FS is not set


I'll recompile the kernel and try again.
