Project for integration Boost libraries into AOSP.

Project supports static and shared libraries linkage and includes:

  • repo manifests - to get Boost source codes from https://git@github.com/boostorg/
  • Android Soong build scripts - to compile Boost libraries in AOSP tree
  • usage examples

Fetching Boost sources to AOSP tree and compiling them

  1. Add project to AOSP tree

Add this project to your AOSP manifest and use repo sync to download it or simply clone it via git clone:

mkdir -p vendor/nkh-lab
$ cd vendor/nkh-lab
$ git clone https://github.com/nkh-lab/aosp-boost.git
  1. Fetch required version of Boost source codes

This is performed by selecting the appropriate manifest file from the manifests folder.

Manifest file can be copied to your AOSP repo local_manifests folder: (e.g.: .repo/local_manifests/aosp-boost-1_72_0.xml) or linked:

$ mkdir -p .repo/local_manifests
$ cd .repo/local_manifests
$ ln -s ../../vendor/nkh-lab/aosp-boost/manifests/boost-1_72_0.xml boost-1_72_0.xml

or included from other manifest:

<manifest>
...
  <include name="aosp-boost-1_72_0.xml" />
...
</manifest>

After manifest applying use repo sync to fetch Boost source codes.

  1. Apply Boost build script to AOSP tree

Copy or use symlink:

$ cd external/boost
$ ln -s ../../vendor/nkh-lab/aosp-boost/make/boost-1_72_0.bp Android.bp
  1. Compile

All is ready to compile now, just source environment, lunch your target and compile Boost sources:

$ cd external/boost/
$ mm

NCAR Android Automotive Emulator Project can be used as a reference or example to see how the mentioned steps were applied to a real AOSP project.

"Hello Boost" AOSP usage example

This project contains a simple example of using the Boost libraries in AOSP, which can be found at examples/hello_boost.

Given example can be compiled via mm make command (run it after setting environment and target):

$ cd examples/hello_boost
$ mm

or added to whole AOSP build by adding corresponding include in target config file, e.g to device/linaro/hikey/hikey960/device-hikey960.mk for HiKey960 build:

include vendor/nkh-lab/aosp-boost/examples/hello_boost.mk

or

$(call inherit-product-if-exists, vendor/nkh-lab/aosp-boost/examples/hello_boost.mk)

Below is shell output from running hello_boost_shared and hello_boost_static example binaries:

$ adb shell
generic_x86:/ # hello_boost_shared
