xnu-make | Easily build , install and deploy the XNU kernel

xnu-make is a Shell library typically used in Xcode, macOS applications. xnu-make has no bugs, it has no vulnerabilities and it has low support. However xnu-make has a Non-SPDX License. You can download it from GitHub.

The Mac OS X kernel, XNU, is open source and building it from source is fairly straightforward (thanks to yearly instructions by Shantonu Sen). However, building the kernel requires one to install a couple of dependencies that are not available on a Mac OS X installation by default (such as ctfconvert, ctfdump and ctfmerge that are part of the Dtrace project). Since these dependencies are installed in the local Xcode Developer directory, one needs to install them on each new machine that one wants to build XNU on. Similarly, building libsyscall requires one to modify the local Mac OS X SDK in Xcode which might not be desirable. Finally, installing XNU and the respective libsystem_kernel.dylib user-space dynamic library requires a bunch of copying and manual terminal commands to be executed which is not ideal when one wants to quickly deploy a new version of the kernel to a virtual machine for example. This project defines a Makefile that takes care of building XNU, libsyscall and their dependencies without modifying the current SDK. An associated deploy scripts takes care of deploying the kernel and its user-space components to a remote host, such as a virtual machine.
