Development
You can change the kernel and compile your own .deb files:
|
Compile on a 32-bit machine or setup a 32-bit compilation environment on a 64-bit machine |
- Install the programs and tools required for kernel building
$ sudo apt-get install libncurses5 libncurses5-dev kernel-package
- Prepare sources, apply patches and setup config file
$ cd /path/to/itc-linux/kernel/linux-3.2 $ patch -p1 < ../patches/linux_3.2.0-38.61.diff $ patch -p1 < ../patches/compulab.cm-itc.diff $ cp ../config-3.2.37-compulab.cm-itc .config
- Make your modifications and configure the new kernel
$ make menuconfig optional: change CONFIG_LOCALVERSION="-compulab.cm-itc" to "-yourname.cm-itc"
- If you have a more than one processor or more than one core, you can speed things up by running concurrent compile commands. Setup CONCURRENCY_LEVEL=8 for 8 cores
$ export CONCURRENCY_LEVEL=8
- Compile the kernel and create the .deb packages
$ fakeroot make-kpkg --initrd --revision=10.00 kernel_image kernel_headers optional: change revision=10.00 to another custom string, it will appear as part of the .deb file
- The linux-image-*.deb and linux-headers-*.deb packages are created in the parent directory
- Install new .deb packages on the CM-iTC
sudo dpkg -i linux-*.deb
