Fluoride Bluetooth stack
Building and running on AOSP
Just build AOSP - Fluoride is there by default.
Building and running on Linux
Instructions for Ubuntu, tested on 15.10 with GCC 5.2.1.
Install required libraries
sudo apt-get install libevent-dev
Install build tools
- Install ninja build system
sudo apt-get install ninja-build
or download binary from https://github.com/ninja-build/ninja/releases
- Install gn - meta-build system that generates NinjaBuild files.
Get sha1 of current version from here and then download corresponding executable:
wget -O gn http://storage.googleapis.com/chromium-gn/<gn.sha1>
i.e. if sha1 is "3491f6687bd9f19946035700eb84ce3eed18c5fa" (value from 24 Feb 2016) do
wget -O gn http://storage.googleapis.com/chromium-gn/3491f6687bd9f19946035700eb84ce3eed18c5fa
Then make binary executable and put it on your PATH, i.e.:
chmod a+x ./gn
sudo mv ./gn /usr/bin
git clone https://android.googlesource.com/platform/system/bt
Then fetch third party dependencies:
git clone https://github.com/google/googletest.git
git clone https://android.googlesource.com/platform/external/libchrome
git clone https://android.googlesource.com/platform/external/modp_b64
git clone https://android.googlesource.com/platform/external/tinyxml2
And third party dependencies of third party dependencies:
curl https://chromium.googlesource.com/chromium/src/base/+/master/third_party/valgrind/valgrind.h?format=TEXT | base64 -d > valgrind.h
curl https://chromium.googlesource.com/chromium/src/base/+/master/third_party/valgrind/memcheck.h?format=TEXT | base64 -d > memcheck.h
Fluoride currently has dependency on some internal Android projects, which also need to be downloaded. This will be removed in future:
git clone https://android.googlesource.com/platform/system/core
git clone https://android.googlesource.com/platform/hardware/libhardware
git clone https://android.googlesource.com/platform/system/media
Configure your build
We need to configure some paths to make the build successful. Run:
gn args out/Default
This will prompt you to fill the contents of your "out/Default/args.gn" file. Make it look like below. Replace "/home/job" with path to your home directory, and don't use "~" in build arguments:
# Build arguments go here. Examples:
# is_component_build = true
# is_debug = false
# See "gn args <out_dir> --list" for available build arguments.
libhw_include_path = "/home/job/fluoride/libhardware/include"
core_include_path = "/home/job/fluoride/core/include"
audio_include_path = "/home/job/fluoride/media/audio/include"
Then generate your build files by calling
gn gen out/Default
ninja -C out/Default all
This will build all targets (the shared library, executables, tests, etc) and put them in out/Default. To build an individual target, replace "all" with the target of your choice, e.g.
ninja -C out/Default net_test_osi.
