TokTok stack

This repository contains git submodules for all directly supported Tox-related repositories. This ensures that any changes made to any of the submodules are always compatible in the snapshot taken by toktok-stack. Before a toxcore release, toktok-stack must cleanly build with the latest master commit in c-toxcore. Clients, bindings, and support programs must always pass all tests in this snapshot. We don't guarantee security of the snapshot, merely interoperability, so don't rely on the security or even error-freeness of anything here. If you need that, use released versions of the submodules themselves.

Beyond the clients, bindings, and programs directly maintained and supported by the TokTok team, here are some additional repositories of interest that develop their code separately. We hope to integrate some of them into toktok-stack at some point.

• aTox Android Tox client. Developed in a fairly rigorous manner and moves slowly but safely. Not as feature-rich as other clients, but reliable and secure.
• rstox Rust bindings to c-toxcore.
• trifa_material Experimental desktop client using zoxcore (below) written in Kotlin. Works on macOS, Windows, and Linux.
• zoxcore Experimental c-toxcore fork with additional toxav (audio/video) development such as x264 video encoding, an improved messaging protocol (with stable message IDs). Go here if you want to implement your own experimental features in a more fast-paced environment. Features here can eventually be merged back into TokTok's toxcore after more rigorous testing and review.

Dev Containers

See dev containers for details.

Downloading

To download the TokTok stack, use git:

git clone --recursive https://github.com/TokTok/toktok-stack

Configuring

You may pass a compiler config for additional compiler-specific warnings and optimisations. If you use Clang (default on OSX), pass --config=clang. If you use GCC, pass --config=gcc. On Windows, you don't need any compiler flag because we assume it's MSVC.

There are also --config=release and --config=debug and more. See .bazelrc in this repository for more config flags you can pass. If you're using the Docker build, then --config=asan, tsan, and msan are also available.

We recommend copying .bazelrc.local.example to .bazelrc.local and customising it according to the comments in that file.

Building

After installing prerequisites (instructions below), run the following command in the toktok-stack directory:

bazel build //...

Installing prerequisites

To build the stack, first you need to install some software. This guide assumes an installation of Debian GNU/Linux version 9 and that you are in the toktok-stack directory. There is partial support for macOS and FreeBSD, but not all targets can be built on those systems.

Bazel

Install the latest version of Bazel, e.g.:

wget https://github.com/bazelbuild/bazel/releases/download/4.2.1/bazel_4.2.1-linux-x86_64.deb
sudo dpkg -i bazel_4.2.1-linux-x86_64.deb

On OSX:

brew install bazel

On FreeBSD:

sudo pkg install bazel

On Windows:

choco install bazel

Qt5

To build Qt-based binaries such as qtox, you need an installation of Qt development headers and libraries and tools.

sudo apt install qttools5-dev qttools5-dev-tools libqt5svg5-dev

On OSX:

brew install qt

On FreeBSD:

sudo pkg install qt5

On Windows:

choco install qt

If your Qt installation doesn't live in a standard location, make changes to the detector script in tools/workspace/qt.bzl and consider sending us a pull request. If your version of Qt is different, edit WORKSPACE and adjust it in the qt_repository declaration.

Extra development packages

Some libraries have not yet been imported into third_party, so must be installed on the system.

For //qtox:

sudo apt install libasound2-dev libxss-dev

For //toxic:

sudo apt install libxss-dev

On OSX (for both qtox and toxic):

brew install ncurses

On FreeBSD:

sudo pkg install ncurses

Note that toxic also needs Python 3. See the section on Python for how to install its development files.

Python

To build py-toxcore-c and other programs using Python FFI, you need Python development headers. py-toxcore-c and toxic both need Python 3. Any of 3.5, 3.6, or 3.7 works.

sudo apt install python3.5-dev

On FreeBSD:

sudo pkg install python3

Native javacpp libraries

Streambot needs native libraries that need to be downloaded from Maven.

wget https://repo1.maven.org/maven2/org/bytedeco/javacpp-presets/ffmpeg/3.4.1-1.4/ffmpeg-3.4.1-1.4-linux-x86_64.jar -O third_party/javacpp/ffmpeg/jar/ffmpeg-3.4.1-1.4-linux-x86_64.jar
wget https://repo1.maven.org/maven2/org/bytedeco/javacpp-presets/opencv/3.4.0-1.4/opencv-3.4.0-1.4-linux-x86_64.jar -O third_party/javacpp/opencv/jar/opencv-3.4.0-1.4-linux-x86_64.jar

Troubleshooting

Xcode version must be specified to use an Apple CROSSTOOL

Try running the following:

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
sudo xcodebuild -license
bazel clean --expunge
