Building (Linux Binary)

We assume you're using Ubuntu or Debian.

1. Install Rust.

   curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

2. Install required dependencies.

   sudo apt-get install -y libssl-dev libglib2.0-dev pkg-config cmake build-essential libclang-dev libgtk-3-dev librust-alsa-sys-dev libasound2-dev curl wget git

3. Run the build script. It will create an AppImage in the dist directory.

   bash ./linux/build.sh
   # or bash ./linux/build_arm64.sh

Building (Windows Binary)

1. Install Rust.

   curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

2. Install the Rust target and toolchain for x86_64-pc-windows-gnu.

   rustup target add x86_64-pc-windows-gnu
   rustup toolchain install stable-x86_64-pc-windows-gnu

3. Install mingw-w64.

   sudo apt-get install -y mingw-w64

4. Ensure mingw-w64 is using the POSIX threading model.

   sudo update-alternatives --install /usr/bin/x86_64-w64-mingw32-gcc x86_64-w64-mingw32-gcc /usr/bin/x86_64-w64-mingw32-gcc-win32 60 &&
   sudo update-alternatives --install /usr/bin/x86_64-w64-mingw32-gcc x86_64-w64-mingw32-gcc /usr/bin/x86_64-w64-mingw32-gcc-posix 90 &&
   sudo update-alternatives --config x86_64-w64-mingw32-gcc &&
   sudo update-alternatives --install /usr/bin/x86_64-w64-mingw32-g++ x86_64-w64-mingw32-g++ /usr/bin/x86_64-w64-mingw32-g++-win32 60 &&
   sudo update-alternatives --install /usr/bin/x86_64-w64-mingw32-g++ x86_64-w64-mingw32-g++ /usr/bin/x86_64-w64-mingw32-g++-posix 90 &&
   sudo update-alternatives --config x86_64-w64-mingw32-g++

5. Build it.

   cargo build --target x86_64-pc-windows-gnu --release --bin tango

Server

The server is the remote HTTP server-based component that Tango connects to. It doesn't actually do very much, so you can run it on absolutely piddly hardware. All it does is provide signaling by sending WebRTC SDPs around.

If you already have Rust and Perl installed (on Windows, try Strawberry Perl), you can build it like so:

cargo build --release --bin tango-signaling-server

Language support

Tango is fully internationalized and supports language switching based on your computer's language settings.

The order of language support is as follows:

• English (en): This is Tango's primary and fallback language. All Tango development is done in English.

• Japanese (ja): This is Tango's secondary but fully supported language. All text in the UI, barring some extremely supplementary text (e.g. the About screen) is expected to be available in Japanese. If new UI text is added, a Japanese translation SHOULD also be provided. Tango releases MUST NOT contain missing Japanese text.

• All other languages: These are Tango's tertiary languages. Support is provided on a best effort basis and translations are provided as available.
