Hello Mageia Users, linux-userspace-headers contains the headers for the source code of Linux kernel. All source code necessary to compile a new kernel is included in two packages linux-userspace-headers, and kernel-source. You will need to install both linux-userspace-headers (needed for general Linux compilation), and kernel-source in order to compile a new kernel. The kernel is the central process of your Linux machine, the mediator between the hardware and your programs. It is responsible for memory allocations, process managing, device access... Although modern kernels are very flexible thanks to dynamic modules, you may need to compile your own kernel for various reasons: your found a new module which need a more recent kernel, you need a feature of a new kernel, etc... Here is a short sum-up of what you can find in the Kernel-HOWTO. Consult it in case of a problem or if the shortcut here provided does not meet your needs. You should also consult the README of kernel-sources. 1. Configure your new kernel You should never build a kernel as root, so as a normal user: Copy the source in /usr/src/linux/ to ~/kernel/ Change to ~/kernel/ and clean-up previous compilations, by issuing "make mrproper", In console mode, run "make menuconfig", Under X11, run "make xconfig". Then configure all sections of your kernel making each feature you need available constantly or as a module. Note that you should compile most features as a module, as it consume less memory, taking into account that some of them cannot be modules as you may need them at boot time, before dynamic modules be loaded... 2. Compile it Just issue "make ARCH=<arch>" where <arch> is the one you want to build, like "i386" or "x86_64" to create a compressed kernel image and the modules you configured. 3. install your new kernel Now you need root privilegies, so: Issue "su" and enter root password. Issue "make ARCH=<arch> modules_install" This will copy your modules and needed files to /lib/modules/ Issue "make ARCH=<arch> install" This will copy your new kernel and system.map to boot dir (/boot/) with correct names including version, and change respective links. It finally runs installkernel from bootloader-utils which will update the bootloader config (eg: grub) in order to take into account your new kernel. 4. Reboot your machine... And pray. Anyway if something goes wrong, you just need to reboot and choose your old kernel with lilo.
