[C++] ninja: Add $SHELL support Ninja always executes commands with /bin/sh, which causes problems on Darwin where the builtin echo does not support the -n argument. Use $SHELL -c "cmd" or $SHELL out.rsp to run commands through the shell selected by the makefiles.
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.
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
% ~/src/kati/m2n -j10 % ./ninja.sh
Or
% ./ninja.sh -j10
Note the latter kills the parallelism of goma.
