What's the difference between the various kernel-debug*.rpm files created after rpmbuild?

Question

I build Fedora Linux kernel (rpmbuild -bb --target=`uname -m` kernel.spec) according to this guide, and now I have among others:

• kernel-debug-debuginfo-3.18.6-100.myself.fc20.x86_64.rpm (~360MB)
• kernel-debuginfo-3.18.6-100.myself.fc20.x86_64.rpm (~360MB)
• kernel-debuginfo-common-x86_64-3.18.6-100.myself.fc20.x86_64.rpm (~51MB)
• kernel-debug-3.18.6-100.myself.fc20.x86_64.rpm (~67MB)
• kernel-debug-devel-3.18.6-100.pae_sw_tal.fc20.x86_64.rpm (~10MB)
• some others...

What's the difference between them and which one should I install if I want a development (debug-able build) version?

Answer 1

Basically you can find following information on rpmfind.net just put kernel-debug-debuginfo in the search and it will tell you what it is.

Similarly for other packages.

for e.g.

kernel-debug-debuginfo-3.18.6-100.myself.fc20.x86_64.rpm

This package provides debug information for package kernel-debug. This is required to use SystemTap with kernel-debug-3.18.6-100.myself.fc20.x86_64.rpm

And I think you need kernel-debug-3.18.6-100.myself.fc20.x86_64.rpm (~67MB)

look at the options of rpmbuild for creating less files. Options like --without devel --without debuginfo
