Building From Source

Ubuntu 14.04/16.04 LTS

1. Ensure apt-get is up to date

• sudo apt-get update && sudo apt-get upgrade
• Note: Use sudo apt-get dist-upgrade, instead of sudo apt-get upgrade, in case you have an older Ubuntu 14.04 version

2. Install Python and its development files via apt-get (Python 2 and 3 both work)

• sudo apt-get install python python-dev or sudo apt-get install python3 python3-dev
• Note: The project will only use Python 2 if it can't use Python 3

3. Run the top level CMake command with the following additional flag -DBUILD_PYTHON_BINDINGS:bool=true:

• git clone https://github.com/IntelRealSense/librealsense.git
• cd librealsense/wrappers
• cmake ../ -DBUILD_PYTHON_BINDINGS:bool=true

Note: To force compilation with a specific version on a system with both Python 2 and Python 3 installed, add the following flag to CMake command: -DPYTHON_EXECUTABLE=[full path to the exact python executable]

• make -j4
• sudo make install

4. update your PYTHONPATH environment variable to add the path to the pyrealsense library

• export PYTHONPATH=$PYTHONPATH:/usr/local/lib

5. Alternatively, copy the build output (librealsense2.so and pyrealsense2.so) next to your script.

• Note: Python 3 module filenames may contain additional information, e.g. pyrealsense2.cpython-35m-arm-linux-gnueabihf.so)
