Implement the `file` function to read and write files This allows us to do file reading and writing without $(shell). Besides being simpler, this also allows faster regen times, since we can just stat the files to be read, or directly write to the files that need to be written.
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.
Now AOSP has kati and ninja, so all you have to do is
% export USE_NINJA=true
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 # Use --goma if you are a Googler. % ./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
