Building BARK From Source

The following prerequisites are required to build BARK from source:

• Bazel.build: Build tool used in BARK:
• >= Python3.7-dev and the package python-tk.
• Virtual Python environment: pip install virtualenv==16.7.8
• >= GCC7: C++ compiler for BARK
• We recommend using Visual Studio Code for development

First, clone the BARK repository and enter the folder: git clone https://github.com/bark-simulator/bark.git && cd bark. Create a virtual Python environment and install the dependencies of BARK by running bash install.sh and enter it using source dev_into.sh. Before running any examples or implementing new code, it is advised to make sure all modules of BARK work properly by running all tests using the command bazel test //.... Finally, you are ready to implement your own code or to run the first example that has been built from source using, e.g., bazel run //bark/examples:merging. A detailed video for installing BARK is shown here:

Building BARK on macOS

The description from above also applies for building BARK from source on macOS. If you run into trouble with TKInter have a look here or the Matplotlib TKAgg backend have a look here.

Frequently Asked Questions (FAQs)

Python.h not found

Make sure that there is a 'Python.h' file in the bark/python_wrapper/venv folder.

GCC: Interal Compiler Error: Killed (program cc1plus)

You might be running out of memory during the bazel build. Try limiting the memory available to bark via bazel build //... --local_ram_resources=HOST_RAM*.4 (or any other build or test call).
