Configure Your System

To use the
Intel® oneAPI Rendering Toolkit
(Render Kit) samples, you first need to set up your system as follows:
  1. Install the oneAPI sample browser to access sample sources.
  2. Install development tools to build the samples.
  3. Install graphics and imaging libraries to view interactive sample application.
  4. Install imaging tools to work with sample input and output.
  5. Optional: Install tools to navigate repositories and documentation.

Install the oneAPI Sample Browser

You can access sample applications from the oneAPI sample browser. The browser is distributed as part of the
Intel® oneAPI Base Toolkit
Base Kit
) in the
Install the
Base Kit
Intel® oneAPI Threading Building Blocks
, which is available in both Render Kit and
Base Kit
. No other
Base Kit
components are required. See
Base Kit
product page
for more information and download links.
You can also get the samples manually using Git*.

Install Development Tools

To build samples, install Xcode* and Xcode command line tools for C99- and C++11-capable compiler tools.
  1. Download and install Xcode from the Apple* website or the App Store from the Spotlight* tool.
  2. Open a new terminal.
  3. Install the command line tools for Xcode:
    xcode-select --install
For more information on setting up the command line tools for Xcode, see Building from the Command Line with Xcode FAQ.

Install Homebrew*

Homebrew* (
) is required to install configuration packages. To install Homebrew:
  1. If you are behind proxy, you may need to configure your proxy:
    export http_proxy=http://<user>:<pass>@proxy.<server>.com:<port>
    export https_proxy=http://<user>:<pass>@proxy.<server>.com:<port>
    export HTTP_PROXY=${http_proxy}
    export HTTPS_PROXY=${https_proxy}
    export ALL_PROXY=${http_proxy}
  2. Run the following command from a terminal to install Homebrew:
    /bin/bash -c "$(curl -fsSL"
You can also use other package management systems, such as MacPorts*. However, they are not covered in this guide.

Install CMake* and pkg-config

Although the CMake and
build tools are not required by the oneAPI tools and toolkits, many oneAPI samples are provided as CMake projects and require CMake to build them.
is required to locate libraries needed to complete a build of the application.
Install the tools as follows:
brew install cmake pkg-config
For information about Homebrew, see the official website.

Install Graphics and Imaging Libraries

Some Render Kit samples, such as Intel OSPRay Studio, are interactive and require graphics libraries.
To install the graphics and imaging libraries, do one of the following depending on your Linux distribution:
To install the libraries with Homebrew:
brew install libpng jpeg glfw glew openimageio
Interactive applications use OpenGL*, Cocoa,* and IOKit* frameworks to accelerate lower-level system library. These frameworks come with Xcode.
command installs
the following libraries:
  • libPNG
    is a PNG image loading library for input and output image files.
  • libJPEG
    is a JPEG image loading library for input and output image files.
  • libGLFW3
    is a multiplatform OpenGL API for windowing, input, events.
  • GLEW
    is an OpenGL* extension library.
  • libOpenImageIO
    is a library for reading and writing many image types, in particular, HDR images.

Install Imaging Tools

Render Kit samples and applications often require preprocessed images as input or generate images as output. To convert input and output images, you need to get imaging tools for staging NetPBM filetypes (PPM and PFM). Recommended tool is ImageMagick*. See the ImageMagick website for standalone and package manager install instructions.
To install the tool with Homebrew:
brew install imagemagick

Configure System Security Options

Recent versions of macOS may restrict executing programs built with the Render Kit. Disable execution restrictions as follows to enable executing the programs:
sudo spctl --master-disable
For more security configuration options, run:
man spctl

Set up Environment Variables

To use Render Kit from command line, you need to set up environment variables for Intel oneAPI Toolkit components using a
script. You can find the script in the root folder of your Intel oneAPI Toolkit installation, which is by default
for sudo or root users and
for non-root users.
If you installed the Intel oneAPI Toolkits to a different location, make sure to replace the default path with your custom one in the commands below before running them.
Option 1. Configure environment variables once per session
Each time as you open a new terminal, you need to source the
script as follows:
  • For root or sudo users:
    . /opt/intel/oneapi/
  • For non-root users:
    . ~/intel/oneapi/
Option 2. Configure environment variables to be set up automatically for all sessions
To have the environment automatically set up for your all projects, add the source command to a startup script where it will be invoked automatically.
For example, you can add the
. /opt/intel/oneapi/
(for root users) or the
. ~/intel/oneapi/
(for non-root users) command to your
To make the settings permanent for
accounts on your system, create a one-line
script in your system's
folder and add the source command to the file.
You can manage the
script using a configuration file. This is helpful if you need to initialize specific versions of libraries or a compiler, rather than defaulting to the latest version. For details, see Using a Configuration File to Manage

Optional: Install Tools to Navigate Repositories and Documentation
