Daxa Tutorial

Installing dependencies

Important

This page will explain how to install all the necessary tools to compile the Daxa repository itself, though these things are also required for consumers of Daxa as a dependency. We’ll go over using Daxa as a dependency in the next page. If you have previously worked with Vulkan or C++, you can skip some of these steps. Since those steps are different for Windows and Linux, this page is split into multiple parts. Make sure you follow the steps from the correct heading.

Windows

Visual Studio

In this tutorial, we will be using Clang as our compiler (EDIT: For now, there are some issues with Clang on Windows, so we’ll just use the Visual Studio compiler for now). Clang relies on the Microsoft STL, which we can get most easily by installing Visual Studio and selecting the C++ desktop development component during installation

Clang & Ninja

To install Clang and Ninja, you need to install Chocolatey. To do so, enter this command line into the PowerShell as an administrator:

Terminal window
Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1'))

PowerShell might ask you to enable the running of scripts, which can be enabled by running Set-ExecutionPolicy AllSigned

You can then go ahead and install clang & ninja:

Terminal window
choco install llvm
choco install ninja

Misc tools

You also need to install Git and CMake. To do so, simply download and run the installers from their websites.

Vulkan SDK

The last step is downloading the Vulkan SDK. During installation, keep “Debuggable Shader API Libraries” unchecked since they might clash with glslang later.

Linux

Tools

sudo apt-get update
sudo apt-get install ninja-build clang cmake git
pacman -Syu
pacman -S ninja-build clang cmake git

Vulkan SDK

For the Vulkan SDK, we advise you follow the instructions on lunarg.com, as they’ll go over how to add the necessary sources and such for your package manager, but here are the commands for Ubuntu 22.04 (Jammy):

wget -qO- https://packages.lunarg.com/lunarg-signing-key-pub.asc | sudo tee /etc/apt/trusted.gpg.d/lunarg.asc
sudo wget -qO /etc/apt/sources.list.d/lunarg-vulkan-jammy.list http://packages.lunarg.com/vulkan/lunarg-vulkan-jammy.list
sudo apt update
sudo apt install vulkan-sdk
https://vulkan.lunarg.com/sdk/home#linux

Installing VSCode (Windows & Linux)

This tutorial will use Visual Studio Code as our code editor. You can also use other IDEs such as CLion, but it may be harder to follow the tutorial. We therefore recommend using VSCode with the following extensions:

  1. C/C++ Extension Pack (ms-vscode.cpptools-extension-pack)
  2. GLSL Lint (dtoplak.vscode-glsllint)
