Prerequisite
An i686 host running some flavor of Linux.
Download All the Required Tarballs
First, download the cross toolchain (arm-2005q3-2-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2), mkimage, and the source archive (linux-2.6.12_lsp.1.7.8.tgz):
$ cd /some_directory $ wget -H -c http://downloads.linkstationwiki.net/Uploads/OldUploads/LS_Pro_temporary/CrossToolchains/CodeSourcery/arm-2005q3-2-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2 $ wget -H -c http://downloads.linkstationwiki.net/Uploads/OldUploads/LS_Pro_temporary/CrossToolchains/mkimage $ wget -H -c http://downloads.linkstationwiki.net/LSPro_ARM9/GPL/gpl_ls-gl/linux-2.6.12_lsp.1.7.8.tgz
If the files were not at the locations indicated above, fear not! Just look in every directory on the server (like I did).
Prepare the Environment
Then, install (i.e., untar) the toolchain and mkimage:
$ cd /some_path $ tar -xjf /some_directory/arm-2005q3-2-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2 $ cd bin $ export PATH=`pwd`:$PATH $ cp -p /some_directory/mkimage . $ chmod a+rx mkimage
Strictly speaking mkimage should not go into /some_path/bin. But, hey...
Now untar the source of the kernel in some directory:
$ cd /some_directory $ tar -xzf linux-2.6.12_lsp.1.7.8.tgz $ cd linux-2.6.12_lsp.1.7.8
Ready, Get Set, Build!
While still in some_directory, type the following:
$ make menuconfig [pick and choose the desired features...] $ make uImage
The kernel will be ready at arch/arm/boot/uImage.
Enjoy!
