kati

kati is an experimental GNU make clone. The main goal of this tool is to speed-up incremental build of Android.

How to use for Android

Currently, kati does not offer a faster build by itself. It instead converts your Makefile to a ninja file.

Set up kati:

% cd ~/src
% git clone https://github.com/google/kati
% cd kati
% make

Build Android:

% cd <android-directory>
% source build/envsetup.sh
% lunch <your-choice>
% ~/src/kati/m2n --kati_stats  # Use --goma if you are a Googler.
% ./ninja.sh

You need ninja in your $PATH.

More usage examples

"make clean"

% ./ninja.sh -t clean

Note ./ninja.sh passes all parameters to ninja.

Build a specific target

For example, the following is equivalent to "make cts":

% ~/src/kati/m2n cts
% ./ninja-cts.sh

Or, if your target is built by "make", your can specify the target of ninja.

% ./ninja.sh out/host/linux-x86/bin/adb

Specify the number of default jobs used by ninja

% ~/src/kati/m2n -j10
% ./ninja.sh

Or

% ./ninja.sh -j10

Note the latter kills the parallelism of goma.
