Thread: Systemtap on 10.3

  1. Systemtap on 10.3


    I feel close to getting systemtap to work on 10.3 (perhaps) but,

    In executing the socktop example the following error was noted, there
    seems to be several notes on this on the web but not a clear resolution
    that I understand.


    ../socktop -P UDP
    semantic error: libdwfl failure (missing kernel debuginfo): invalid
    `Elf' handle while resolving probe point kernel.function("dev_queue_xmit")

    [Q] Do you use which kernel ? /boot/vmlinuz-2.6.22.13-0.3-debug
    or /boot/vmlinuz-2.6.22.13-0.3-default

    I am trying the debug kernel -> uname -> Linux zap64x2
    2.6.22.13-0.3-debug #1 SMP 2007/11/19 15:02:58 UTC x86_64 x86_64 x86_64
    GNU/Linux

    I guess I am unfamiliar with the debuginfo part, is it a library or the
    above kernel ?

    Anyway I will keep plugging away at it.

    Found my own answer, debuginfo is an rpm which at the moment is only
    supplied for the default kernel, the process of offering it for updates
    is being discussed for 11.0.
