a broken kernel with a ton of bad design choices and copypasted code. It's actually not that bad anymore tho

• Building locally

• Run X server
• Full Linux binary compatibility
• Binary compatibility with other kernels

first make sure you have all submodules. Simply clone like this

git clone --recurse-submodules https://github.com/theverygaming/vix.git

you already cloned the repo? then run git submodule update --init --recursive instead

now to build for x86 you need a few extra dependencies(aside from gcc and make), on ubuntu these are installed by running

sudo apt install nasm gcc-multilib g++-multilib xorriso grub-common grub-pc mtools python3 cmake pkg-config flex bison libncurses5-dev xxd

Now refer to the general build instructions

first you have to configure the kernel, you could either simply use the default config (make alldefconfig) or configure it yourself (make menuconfig)

then you can simply build with make and then make bootimg-x86-32 (if you have a x86_32 system, otherwise use the CROSS_COMPILE environment variable or on x86_64 you can use CXXFLAGS="-m32 -march=i386" LDFLAGS="-m elf_i386")

a bootable iso named vix.iso will be created

for other architectures look at the GitHub actions workflow

cd kernel
make clangd_compile_flags_txt
