For x86 architectures, verify the 64-bit kernel option unset, and select the processor family as appropriate for the machine's processor.

Compiling and installing

With the configuration now done, it is time to compile and install the kernel. Exit the configuration and start the compilation process:

root #make && make modules_install


Note
It is possible to enable parallel builds using make -jX with X being an integer number of parallel tasks that the build process is allowed to launch. This is similar to the instructions about /etc/portage/make.conf earlier, with the MAKEOPTS variable.

When the kernel has finished compiling, copy the kernel image to /boot/. This is handled by the make install command:

root #make install

This will copy the kernel image into /boot/ together with the System.map file and the kernel configuration file.
