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":
% ./ninja.sh cts
Or, if you know the path you want, you can do:
% ./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.
