Add --top_level_phony This makes the real_to_phony checks assume that any leaf dependencies that doesn't have a '/' in it is a PHONY target. We need this in Android since we now have two separate Kati instances both writing out ninja files from Makefiles. Without this, the real_to_phony checks don't work when the PHONY target is defined in the other Kati instance. Change-Id: Ib0aeee8e57e47b37adef1f5bed871f909cc4af9d
kati is an experimental GNU make clone. The main goal of this tool is to speed-up incremental build of Android.
Currently, kati does not offer a faster build by itself. It instead converts your Makefile to a ninja file.
For Android-N+, ckati and ninja is used automatically. There is a prebuilt checked in under prebuilts/build-tools that is used.
All Android's build commands (m, mmm, mmma, etc.) should just work.
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 % ./ninja.sh
You need ninja in your $PATH.
% ./ninja.sh -t clean
Note ./ninja.sh passes all parameters to ninja.
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
