Where does systemtap look for debuginfo and sources ?

[A, Satheeshpaul (EXT-Other - IN/Bangalore)]

Hi,

I am having trouble in probing a module that did not come with the RHEL
5.4 distribution. I have installed the kernel-debuginfo & kernel-devel
packages. The kernel-debuginfo packages puts the debug-build modules
under "/usr/lib/debug/lib/modules/2.6.18-164.el5/kernel/" . I have
copied my module (built with -g and no optimisation) in this location. I
also copied the sources of this module under
"/usr/src/debug/kernel-2.6.18/linux-2.6.18.x86_64/net". But systemtap is
still not able to find the probe point.

Below is the probe that fails to build.

probe module("quicksec").function("ssh_interceptor_init")
{
   printf("---%s----\n", pp( ));
}

Error:
semantic error: no match while resolving probe point
module("quicksec").function("ssh_interceptor_init")
semantic error: no probes found

I am sure I am not placing the debug-build module or the sources in the
correct location for systemtap to pick. But I could not see any
documentation on this.

Can anyone help?

With Regards,
Satheesh.
