newbie question : compiling kernel and debug info.


When I started using systemtap, I had tried to compile my kernel and use systemtap (binary -- came with fedora) on it. But I was not very successful (I used to get a number of symbol mismatch/function not found ..etc errors) and finally I started using systemtap with Fedora kernel. So far, it has worked fine.

$ stap -V
SystemTap translator/driver (version 0.6.2/0.127 built 2008-03-27)

$ uname -a
Linux mophia.sfbay.sun.com 2.6.23.17-88.fc7 #1 SMP Thu May 15 00:02:29 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux


Some questions on compiling custom kernels
1. Should I compile and replace my existing systemtap with a newer version in order to use it for a custom-compiled kernel? (Is there any relation between system tap binary and kernel on which it is used?)


2. How to compile modules with debuginfo?

Thanks,
Om.
