5.6 Compiling the Kernel (uImage)
y
1. As root, change to the kernel source directory
DD = 2 digit day
HH = 2 digit hour
mm = 2 digit minutes
# date 031310002006
# make mrproper
4. Create a new .config file by copying the config-save file to
.config
# cp config-save .config
# make uImage
Unlike other some other Linux distributions, the Gentoo kernel can be nativel
compiled on the HW400c/2 following standard Linux kernel build procedures.
Rebuilding the kernel is necessary when changing the kernel configuration
parameters.
These are the basic steps necessary to compile the kernel natively on the HW400c/2;
# cd /usr/src/linux-2.6.9-gigateak
2. Set the date (see man date) MMDDHHmmYYYY
Where MM = 2 digit month
YYYY = 4 digit year
3. Clean up old .config files
5. Create the changes in the .config file
# make oldconfig
6. Compile the kernel
# make
7. Create the kernel binary (uImage)
8. On the host machine, copy uImage to /tftpboot
# cp uImage /tftpboot/.
ASCII terminals, such as Minicom and Hyperterminal, may not run menu driven kernel configuration
utilities such as menuconfig properly from the HW400c/2 console. There two options here, ssh to
the HW400c/2 from the host and use menuconfig from the host path:
/opt/gentoo/usr/src/linux,
then finish the compile from the HW400c/2, or on the
HW400c/2, use the config utility (make config), which will step through each option individually.
