Hi List,
I do the following on Fedora kernel src rpm : (1) rpm -ivh kernel-xxx.rpm (2) Go to ~/rpmbuild/SPECS dir (2) rpmbuild -bp kernel.specs --nodeps
then in the ~/rpmbuild/BUILD/ dir I get kernel-xxx dir where in there are two source dir - (1) linux-xxx <-------- A (2) vanilla-xxx <-------- B
Why are these two dir created - How do I use the configuration file /boot/config-xxx to build vmlinuz and initrd image ?
Directory B is vanilla kernel source which is standard kernel source. This is a same source which is available on kernel.org Directory A is actually for source which has been modified by user. In this case it will have patches from FEDORA above standard kernel from kernel.org. To build vmlinuz and initrd image copy /boot/config-xxx to Directory A (linux-xxx) and run "sudo make oldconfig" then follow normal compilation steps
Which dir A or B sould I use for building ?
You should be using directory A
