NVIDIA DALI
===========
This repository contains extra dependencies required to setup a whole development
environment for NVIDIA DALI project.

To obtain only the required code for DALI build (without unnecessary git history) please:

.. code-block:: bash

  git clone https://github.com/NVIDIA/DALI_deps
  git submodule init
  git submodule update --depth 1 --recursive

The repository consists mostly of externally hosted subrepositories:

Installing dependencies locally
===============================

In order to conduct `Bare Metal DALI build <https://docs.nvidia.com/deeplearning/dali/main-user-guide/docs/compilation.html#bare-metal-build>`_,
you need to install all the above dependencies (or turn off particular features with CMake variables like ``BUILD_NVDEC=OFF`` etc...).
``build_scripts`` folder contains the recipes, how to build every particular dependency.


This is automated using ``build_deps.sh``, which will build all the dependencies and install them to the local environment. We recommend not
running this script as sudo. Instead, you can specify a prefix path::

    export HOST_INSTALL_PREFIX=$HOME/prefix/
    export PATH=$HOME/prefix/bin:$PATH
    export LD_LIBRARY_PATH=$HOME/prefix/lib:$LD_LIBRARY_PATH
    export CPATH=$HOME/prefix/include:$CPATH
    bash -ex build_scripts/build_deps.sh
