fedora 8 update to 2.6.24.3-12.fc8, error: linux/hrtimer.h: No such file or directory

[Frank Singleton <javabear at tx dot rr dot com>]

Hi,

Thanks for the great instrumentation tool :-)

Was happily playing with systemtap until I took a kernel/debuginfo 
update today on fedora 8.

now simple stap example fails to compile

Any thoughts ??

run a simple stap to see if all is well, but it complains about missing 
file.

So check autoconf-hrtimer-rel.c

[root@cray frank]# more /usr/share/systemtap/runtime/autoconf-hrtimer-rel.c
#include <linux/hrtimer.h>

int x = HRTIMER_REL;  /* as opposed to HRTIMER_MODE_REL */
[root@cray frank]#

Lets check hrtimer.h location

[root@cray frank]# locate hrtimer.h
/usr/src/debug/kernel-2.6.24/linux-2.6.24.i686/include/linux/hrtimer.h
/usr/src/kernels/2.6.23.15-137.fc8-i686/include/linux/hrtimer.h
