warning::debuginfo - systemtap missing-debuginfo warnings
For many symbolic probing operations, systemtap needs DWARF debuginfo for
the relevant binaries. This often includes resolving function/statement
probes, or $context variables in related handlers. DWARF debuginfo may
be found in the original binaries built during compilation, or may have
been split into separate files. The
environment variable affects where systemtap looks for these files.
If your operating system came from a distributor, check with them if
debuginfo packages or variants are available. If your distributor does
not have debuginfo-equipped binaries at all, you may need to rebuild it.
- kernel debuginfo
For scripts that target the kernel, systemtap may search for the
file created during its original build. This is distinct from the
file, and much larger. If you have a hand-built kernel, make sure
it was built with the
- process debuginfo
For scripts that target user-space, systemtap may search for debuginfo.
If you have hand-built binaries, use
to compile them.
On some platforms, systemtap may advise what commands to run, in order
to download needed debuginfo. Another possibility is to invoke systemtap
script included with systemtap may be able to download the
appropriate kernel debuginfo. Another possibility is to install and
remote-compilation instance on a machine on your network, where
debuginfo and compilation resources can be centralized. Try the
option, in case such a server is already running.
