# Installs librealsense and pyrealsense2 on the Jetson NX running Ubuntu 18.04
# and using Python 3
# Tested on a Jetson NX running Ubuntu 18.04 and Python 3.6.9 on 2021-01-25
sudo apt-get update && sudo apt-get -y upgrade
sudo apt-get install -y --no-install-recommends \

    python3-dev

# Install the core packages required to build librealsense libs
sudo apt-get install -y git libssl-dev libusb-1.0-0-dev pkg-config libgtk-3-dev
# Install Distribution-specific packages for Ubuntu 18
sudo apt-get install -y libglfw3-dev libgl1-mesa-dev libglu1-mesa-dev

cd librealsense

./scripts/setup_udev_rules.sh

export PATH=/usr/local/cuda-10.2/bin/:$PATH

# Now the build
mkdir build && cd build
## Install CMake with Python bindings (that's what the -DBUILD flag is for)
## see link: https://github.com/IntelRealSense/librealsense/issues/6964#issuecomment-707501049
cmake ../ -DFORCE_RSUSB_BACKEND=ON -DBUILD_PYTHON_BINDINGS:bool=true -DPYTHON_EXECUTABLE=/usr/bin/python3.6 -DCMAKE_BUILD_TYPE=release -DBUILD_EXAMPLES=true -DBUILD_GRAPHICAL_EXAMPLES=true -DBUILD_WITH_CUDA:bool=true
## Recompile and install librealsense binaries
## This is gonna take a while! The -j4 flag means to use 4 cores in parallel
## but you can remove it and simply run `sudo make` instead, which will take longer
sudo make uninstall
sudo make clean
make -j4
sudo make install
