FC3 Release Note

Obtain the kernel-<version>.src.rpm file from one of the following sources:
- The SRPMS directory on the appropriate "SRPMS" CD iso image
- The FTP site where you got the kernel package
- By running the following command:
  up2date --get-source kernel
Install kernel-<version>.src.rpm (given the default RPM configuration, the files this package contains will be written to /usr/src/redhat/)
Change directory to /usr/src/redhat/SPECS/, and issue the following command:
rpmbuild -bp --target=<arch> kernel.spec
(Where <arch> is the desired target architecture.)
On a default RPM configuration, the kernel tree will be located in /usr/src/redhat/BUILD/.
In resulting tree, the configurations for the specific kernels shipped in Fedora Core 3 are in the /configs/ directory. For example, the i686 SMP configuration file is named /configs/kernel-<version>-i686-smp.config. Issue the following command to place the desired configuration file in the proper place for building:
cp <desired-file> ./.config
Issue the following command:
make oldconfig

An exploded source tree is not required to build kernel modules against the currently in-use kernel.

For example, to build the foo.ko module, create the following file (named Makefile) in the directory containing the foo.c file:


obj-m    := foo.o

KDIR    := /lib/modules/$(shell uname -r)/build
PWD    := $(shell pwd)

default:
    $(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules

Issue the make command to build the foo.ko module.
