Removed the old build symlink in /lib/modules/2.6.17-1.2462.fc6xen. Then made a new symlink: ln -s ../../../usr/src/kernels/2.6.17-1.2462.fc6-xen-x86_64/build build Also had to deal with bz#197220 cd /usr/src/kernels/2.6.17-1.2462.fc6-xen-x86_64/build touch include/config/auto.conf This allowed the very simple systemtap script to run: /usr/bin/stap -vv -e 'probe begin { log("hello, world"); }' The change in the symbolic link and touching the include/config/auto.conf allow the systemtap testsuite to run on a xen kernel. change QA contact Checked to make sure that this bug doesn't affect RHEL5. RHEL5 works fine on the 2.6.18-8.1.6el5-xen-i686. It looks like the problem has been resolved in the newer versions. |
Description of problem: The directory structure used for /usr/src/kernel/2.6.17-1.2462.fc6-xen-x86_64 doesn't match the directory structure used for other kernel-devel packages. This prevents third party modules, e.g. systemtap modules from building. Version-Release number of selected component (if applicable): kernel-xen-devel-2.6.17-1.2462.fc6 How reproducible: Always Steps to Reproduce: 1. Have system running kernel-xen. Also have kernel-xen-devel, kernel-xen-debuginfo, and systemtap installed installed. 2. As root attempt to run a simple hello world systemtap script. /usr/bin/stap -vv -e 'probe begin { log ("hello world") }' Actual results: Created temporary directory "/tmp/stapz5uekT" Searched '/usr/share/systemtap/tapset/2.6.17-1.2462.fc6xen/x86_64/*.stp', match count 0 Searched '/usr/share/systemtap/tapset/2.6.17-1.2462.fc6xen/*.stp', match count 0Searched '/usr/share/systemtap/tapset/2.6.17/x86_64/*.stp', match count 0 Searched '/usr/share/systemtap/tapset/2.6.17/*.stp', match count 0 Searched '/usr/share/systemtap/tapset/2.6/x86_64/*.stp', match count 0 Searched '/usr/share/systemtap/tapset/2.6/*.stp', match count 0 Searched '/usr/share/systemtap/tapset/x86_64/*.stp', match count 1 Searched '/usr/share/systemtap/tapset/*.stp', match count 26 Searched '/usr/share/systemtap/tapset/LKET/2.6.17-1.2462.fc6xen/x86_64/*.stp', match count 0 Searched '/usr/share/systemtap/tapset/LKET/2.6.17-1.2462.fc6xen/*.stp', match count 0 Searched '/usr/share/systemtap/tapset/LKET/2.6.17/x86_64/*.stp', match count 0 Searched '/usr/share/systemtap/tapset/LKET/2.6.17/*.stp', match count 0 Searched '/usr/share/systemtap/tapset/LKET/2.6/x86_64/*.stp', match count 0 Searched '/usr/share/systemtap/tapset/LKET/2.6/*.stp', match count 0 Searched '/usr/share/systemtap/tapset/LKET/x86_64/*.stp', match count 0 Searched '/usr/share/systemtap/tapset/LKET/*.stp', match count 13 Pass 1: parsed user script and 40 library script(s) in 80usr/0sys/103real ms.
