Has anyone tried to use systemtap on SUSE SLES10? I was able to run a
simple "hello world" script but I always get errors when trying to
access kernel functions. For example, this script:

<<<
global reads

probe begin {
printf("probe beginning\n")
}

probe syscall.read {
reads [execname()] <<< count
}

probe end {
foreach (prog_name in reads) {
  printf("Name: %s, # Reads: %d, Total Bytes: %d, Avg: %d\n",
       prog_name, @count(reads[prog_name]),
       @sum(reads[prog_name]), @avg(reads[prog_name]))
}
}
>>>

Gives the following error:

semantic error: libdwfl failure (dwfl_linux_kernel_report_offline): No
such file or directory while resolving probe point
kernel.function("sys_read")
semantic error: no match for probe point while resolving probe point
syscall.read
Pass 2: analysis failed. Try again with more '-v' (verbose) options.

Am I missing some package?

Thank you. Kind regards,
