Compiling Linux kernel

Lambdo uses a Linux kernel compiled from source. This is a guide to compile the kernel.

Install dependencies

bash

sudo apt update
sudo apt install git build-essential bc flex bison curl tar

bash

sudo dnf install git gcc make xz bc flex bison diffutils curl tar

bash

sudo pacman -Syu git gcc make xz bc flex bison diffutils curl tar

Download and extract the kernel source:

bash

curl -L https://cdn.kernel.org/pub/linux/kernel/v6.x/linux-6.5.9.tar.xz --output linux.tar.xz
tar xf linux.tar.xz

Generate the default configuration:

bash

cd linux
sudo make tinyconfig

Compile the kernel:

bash

KCFLAGS="-Wa,-mx86-used-note=no" sudo make bzImage -j `nproc`

The image is located at arch/x86/boot/compressed/vmlinux.bin
