TomatOS

A 64bit tomato kernel

Building

Toolchain

First you would need to build a custom clang toolchain, the reason for this is that we use a patched version of the sources to allow c code to make use of the llvm coroutines builtins.

You can get the download the patched sources from here (note how the branch is not master but tomatos), simply follow the normal guidelines of building clang, you will also need to build ld.lld.

Kernel

To build the kernel image simply invoke make:

make PREFIX=<path to clang bin dir> -j

To create an image with limine:

make PREFIX=<path to clang bin dir> image -j

To create an image and run it in qemu:

make PREFIX=<path to clang bin dir> qemu -j

Make Options:

• DEBUG=[1/0] - allows to turn on/off debug mode (default is 1)
