Source code is not installed by default, and it's
not included on the 4 "binary" CDs that you use to install Fedora. Which
particular source are you looking for?
I'm particulary looking for Bluez source code. But I prefer to have all source code because I want to rebuild My kernel.
in which repertory is the files '.menuconfig.log' because i want to use the menuconfig with: #make menuconfig
The Fedora sources are available in SRPMs at: http://download.fedora.redhat.com/pub/fedora/linux/core/3/SRPMS/
Also at most mirrors of this site (choose one local to you). Do you know how to handle SRPMs?
If you want to build your own kernel, see the HOWTO at: http://crab-lab.zool.ohiou.edu/kevin/kernel-compilation-tutorial-en/
