ArrayFire Installer

Installing ArrayFire couldn't be easier. Navigate to https://arrayfire.com/download and download the installer for your architecture and operating system. Although you could build ArrayFire from source, we recommend using our installers as we have packaged together all of the necessary dependencies to give you the best performance.

We provide installers for Windows, Linux, and macOS. There are two installers for each operating system: one with graphics support and the other without graphics support. Download the installer with graphics support if you would like to be able to do high performance visualizations using our Forge library. Otherwise, download the installer without graphics support.

Make sure you have the latest device drivers installed on your system before using ArrayFire. If you are going to be targeting the CPU using ArrayFire’s OpenCL backend, you will need to have the OpenCL runtime installed on your system. Drivers and runtimes should be downloaded and installed from your device vendor’s website.

Install Instructions

Windows

Prior to installing ArrayFire on Windows, download install the Visual Studio 2015 (x64) runtime libraries.

Once you have downloaded the ArrayFire installer, execute the installer as you normally would on Windows. If you choose not to modify the path during the installation procedure, you'll need to manually add ArrayFire to the path for all users. Simply append AF_PATH%/lib to the PATH variable so that the loader can find ArrayFire DLLs.

Linux

Once you have downloaded the ArrayFire installer, execute the installer from the terminal as shown below. Set the --prefix argument to the directory you would like to install ArrayFire to - we recommend /opt.

./Arrayfire_*_Linux_x86_64.sh --include-subdir --prefix=/opt

Given sudo permissions, you can add the ArrayFire libraries via ldconfig like so:

echo /opt/arrayfire/lib > /etc/ld.so.conf.d/arrayfire.conf
sudo ldconfig

Otherwise, you will need to set the LD_LIBRARY_PATH environment variable in order to let your shared library loader find the ArrayFire libraries.

Graphics support

ArrayFire allows you to do high performance visualizations via our Forge library. On Linux, there are a few dependencies you will need to install to enable graphics support:

FreeImage Fontconfig GLU (OpenGL Utility Library)

We show how to install these dependencies on common Linux distributions:

Debian, Ubuntu (14.04 and above), and other Debian derivatives

apt install build-essential libfreeimage3 libfontconfig1 libglu1-mesa

Fedora, Redhat, CentOS

yum install freeimage fontconfig mesa-libGLU

macOS

Once you have downloaded the ArrayFire installer, execute the installer by either double clicking on the ArrayFire pkg file or running the following command from your terminal:

sudo installer -pkg Arrayfire-*_OSX.pkg -target /

For more information on using ArrayFire on macOS, visit the following page.

NVIDIA Tegra devices

ArrayFire is capable of running on TX1 and TX2 devices. The TK1 is no longer supported.

Prior to installing ArrayFire, make sure you have the latest version of JetPack (v2.3 and above) or L4T (v24.2 and above) on your device.

Tegra prerequisites

The following dependencies are required for Tegra devices:

sudo apt install libopenblas-dev liblapacke-dev

Testing installation

After ArrayFire is finished installing, we recommend building and running a few of the provided examples to verify things are working as expected.

On Unix-like systems:

cp -r /opt/arrayfire/share/ArrayFire/examples /tmp/examples
cd /tmp/examples
mkdir build
cd build
cmake -DASSETS_DIR:PATH=/tmp ..
make
./helloworld/helloworld_{cpu,cuda,opencl}

On Windows, open the CMakeLists.txt file from CMake-GUI and set ASSETS_DIR variable to the parent folder of examples folder. Once the project is configured and generated, you can build and run the examples from Visual Studio.
