0. ENVIRONMENT SETUP (Common ANDROID and NON-ANDROID builds)

Create Android lunch shell and add external toolchain

bash . build/envsetup.sh . device/google/contexthub/firmware/toolchain-setup.sh lunch

First time you run toolchain-setup.sh it will download and install

the external toolchain from linaro launchpad.

Next time it will simply define environment variables for it.

1. NON-ANDROID BUILD (unsupported)

1.1. to build any OS variant, run

make -C <variant_path>

where <variant_path> is relative path to OS variant dir;

or simply "cd <variant_path>" and run "make".

for local variants, variant_path is variant/<variant_name>

1.2. to build nanoapp, run

make -C <nanapp_path>

where <nanoapp_path> is relative path to nanoapp;

or simply "cd <nanoapp_path>" and run "make".

for local nanoapps, nanoapp_path is app/<app_name>

2. ANDROID BUILD

2.1 to build nanohub OS and all apps

execute

make auxiliary -j24

2.2 Build Artifacts Location

Artifacts will be found in

$OUT/aux/$(AUX_OS_VARIANT)/$(AUX_OS)-$(AUX_ARCH)-$(AUX_CPU)/bin

e.g. for nanohub OS on STM32 series MCU (ARM cortex m4 core) for Angler this will be in

$OUT/aux/angler/nanohub-stm32-cortexm4/bin

where $OUT is lunch shell environment variable

2.3 partial build or build without dependencies

Any app or static library could be built in isolation with

mmm

or, for current path

mm

Nanohub OS system image is only built with

m auxiliary
