Compile android targeted binary on android.

mini-ndk

Provide zig with the ability to compile for android targeted binary.

The story

Compiling android targeted biarny is a pain on aarch64 linux and android, because ndk is not distributed on them, finally i found a repo is able to compile android targetd binary.

The llvm-cross-toolchains.

I then learned that we can assemable a complete toolchain by placing llvm resource dir to the right and passing the sysroot argument to toolchain. this link Assembling a Complete Toolchain will give more details.

By comparing the verbose log bettween the working toolchain and my cripple one, i finnally figured it out how to make it work, and i wrote this automatic script.

Why do i choose zig rather than origional llvm toolchain?

• zig can run on raw android (not prooted, not chrooted).
• zig updates and release toolchain frequently.
• zig can build for many many targets already.
• zig release package is much smaller than llvm relase package.

I create this script to make zig to be able to compile android targeted binary on raw android.

Setup instruction

Download these required resources:

• zig-ndk (this script)
• zig
• ndk from google site or github release
