C/C++ dependencies

Native code

  • Toxcore
  • Toxav
    • We require the latest git version of these libraries, so you will need to build them yourself.
  • CMake (>= 2.8.7)
    • Debian/Ubuntu: cmake
  • protobuf 3.0.0
    • Debian/Ubuntu: You need to build this from source.
  • Clang 3.5 or newer (older versions of clang segfault. G++ support is untested, the build script enforces clang-3.5 for now. If you do not have clang 3.5 installed, your build may fail.)
    • Debian/Ubuntu: clang-3.5


  • Build and install toxcore and toxav.
  • Run the sbt console with sbt.

Now you can use compile to build, test to run unit tests (these are a lot of tests with high timeouts, might take 10 minutes or longer), and package to create a jar and the native library.

Developing on Mac OS X

Getting the required tools for development on OS X is very easy. If you have XCode installed, you will already be able to compile the C++ part of tox4j,

Importing in IDEA

To import the project in IDEA, launch IDEA and:

  • On the "Welcome to IntelliJ IDEA" screen, select "Import Project".
  • Select the directory jvm-toxcore-c (this git repository).
  • Press "OK".
  • Select "Import project from external model".
  • Select "SBT".
  • Press "Next".
  • Select "Use auto-import", "Download sources and docs", and "Download SBT sources and docs".
  • Create and select a JDK if you don't have one, yet.
  • Press "Finish".

Now you need to wait while IDEA builds the project info from the SBT project. When it is done, it shows a list of modules, all are selected. Leave them selected and press "OK". After IDEA opens, it will say "Unregistered VCS root detected". Press "Add root" so you can use git from IDEA. If you have the protobuf extension installed, you can register the proto files with that as well (another notification will show for that).
