stap fails with: "error: implicit declaration of function ‘unregister_uprobe’"

[Alain Kalker]

Trying to run this simple probe:

# stap -v -e 'probe process("ls").function("*").call {
           log (probefunc()." ".$$parms)
           }' -c 'ls -l'

fails with the following errors:

I think this may be related to the changes made for Bug #1054274 , in particular with handling the name change from 'uprobe_register' -> 'register_uprobe' et al. See uprobes-inode.c , lines 18-35.

I believe this problem was fixed back in version 1.8, as well as the current version of 2.0.

[Launchpad Janitor (janitor)]

This bug was fixed in the package systemtap - 2.1-1~experimental1

---------------
systemtap (2.1-1~experimental1) experimental; urgency=low

  * New upstream release (Closes: #690404, #701365, #701365)
    (LP: #803549, #1130626, #1075772).
  * Drop patches that are part of the new upstream release:
    - manpage-syntax1.diff
    - spelling-fixes1.diff
    - spelling-fixes2.diff
    - manpage-paths1.diff
    - fix.CVE-2012-0875.diff
  * Add patches that fix various lintian warnings. These have all
    been accepted upstream so we can get rid of them in the next
    release (thanks Frank Ch. Eigler!):
    - 0001-man-stap.1-escape-minus-sign-properly.patch
    - 0002-man-stap.1-fix-typo.patch
    - 0003-man-stapprobes.3stap-escape-minus-sign-properly.patch
    - 0005-Add-missing-usr-bin-env-stap-to-some-examples.patch

  * Backport patch to support unreadable System.map on Ubuntu:
    - 0001-translator-tolerate-unavailable-System.map.patch
  * Add patch to suggest reading README.Debian if anything
    fails. Usability testing shows that surprisingly few users
    will find it otherwise :-) This patch can not be forwarded
    upstream but it is very simple.
    - suggest-readme.debian.diff
  * Upload to experimental since wheezy is frozen.
  * Drop systemtap-grapher binary package as it has been
    removed by upstream. Remove its build-dependencies
    libgtkmm-2.4-dev, libboost-dev and libglademm-2.4-dev as well.
  * Add powerpcspe to the architecture list (Closes: #700161).
  * Ship stap-prep to help users figure out what
    debug symbol and header packages they need to install and mention
    this in README.Debian.
  * Add patches to make stap-prep work on Debian:
    - 0001-Prepare-stap-prep-for-support-for-non-rpm-systems.patch
    - 0002-stap-prep-add-support-for-deb-based-systems.patch
    - 0003-man-add-man-page-for-stap-prep-1.patch

  * Add patch to improve error messages:
    - 0001-Suggest-running-stap-prep-after-all-failures.patch
  * Enable emacs addon that makes editing .stp files easier.
  * Ensure that build log shows full build commands.
  * Bump Standards-Version to 3.9.4, no changes were needed.
