This repo is the kitchen used to create headers and Makefiles for building *box with the command ndk-build in NDK (more info here).
You have to clone sources of *box to the current directory and checkout to your desired tag before running the scripts here.
Building busybox requires an excessive amount of source code patching, and Makefiles are extremely difficult to create.
./busybox.sh patch to apply required patches
./busybox.sh generate to generate required Makefiles and headers
Toybox is used in AOSP, so it is much easier to compile using NDK.
./toybox.sh patch to apply required patches
./toybox.sh generate to generate required Makefiles and headers
