Hi,
I am trying to run systemtap on arm64 kernel based on 3.14-rc3 with
kprobes patches.
[Systemtap recipe from: http://patches.openembedded.org/patch/66343/]
While running sample hello program, the systemtap is failing to
generate the source file and failing with errors -pasted- below.
Please let me know what could be going wrong here.
Thanks,
Sandeepa

The error::pass4 page advises that such problems can occur if your
kernel is much newer than your version of systemtap. Try again
with git systemtap.

Hi Frank,
I have tried with latest changes from git systemtap (commit#

What is the latest kernel revision verified with systemtap? Our
patches are based out of 3.14-rc3 kernel.
Thanks,
