             Bug #: 13100
           Summary: Building tracepoint cache all at once fails when
                    kernel debuginfo installed
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: translator
        AssignedTo: systemtap@sourceware.org
        ReportedBy: mjw@redhat.com
    Classification: Unclassified


Commit d4393459 introduced deeper searching for "hidden" tracepoints.
This uses the include files from the kernel debuginfo package.
But this seems to make the first pass of trying to create a tracepoint cache in
one go always fail because now headers are included two times (ones under
/lib/module/.../build/include and once under
/usr/src/debug////////kernel.../include/

Example:
$rm -rf ~/.systemtap
$ stap -e 'probe kernel.trace("sched_wakeup") { log("wake!"); exit(); }'
Warning: make exited with status: 2
[... wait some long time ...]
wake!

Things still work because after that first attempt it tries building each
tracepoint header file individually. So it is really just a transient warning,
causing fallback to a slow caching method.

More verbose logs:
