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:

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

Installing dependencies locally

In order to conduct Bare Metal DALI 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 `
