Getting Started

Obtain a Steinwurf License

Before you download or use our libraries, you MUST obtain a valid Steinwurf license.

Please read the license terms at and fill out the license request form with the appropriate details.

Tools Needed

If you wish to build our libraries with our build system, you will need to install the following tools:

  1. C++14 compliant compiler: A C++ compiler that supports the C++14 standard. This can be g++, clang or msvc.
  2. Git: The git version control system for managing our libraries.
  3. Python: We use the Python-based waf build system.

The following sections describe how to install the tools on different platforms.

Download Tools (Ubuntu or other Debian-based distributions)

Get the dependencies using the following command:

sudo apt-get install g++ python git-core

Download Tools (Windows)

  1. C++14 compliant compiler: You need a working C++14 compiler. The latest supported version is Visual Studio 2017: you can get the Community, Professional or Enterprise versions from the main Visual Studio download page or the Express version or you can install the standalone Build Tools for Visual Studio 2017 (which is a smaller package). If you need an earlier version, you may also use Visual Studio Express 2015 for Desktop.


If you get the following compiler error:

Cannot open include file: 'corecrt.h'

Then most likely, you need to install the Windows Universal CRT SDK, please follow the instructions here:

If the waf configure step fails, because mt.exe and rc.exe are missing from these locations:

C:\Program Files (x86)\Windows Kits\10\bin\x64
C:\Program Files (x86)\Windows Kits\10\bin\x86

Then you should install an earlier version of the Windows 10 SDK (10.0.14393) to fix this.

The Visual Studio Command Prompt can be useful to verify your installation. If the VS Command Prompt cannot find your Windows SDK installation, then please check that the %SystemRoot%\System32 folder is added to your system PATH.

  1. Python: You need a working Python installation. Find the available download on the Python homepage. If you are in doubt about which version to install, you may use the Python 2.7.15 Windows Installer.
  2. Git: There are several ways to get git on Windows. If you plan to use the waf build scripts to build our examples and unit tests, you should install the Git for Windows tool (version 2.8.x or above).
  3. TortoiseGit (Optional): You can also install the latest version of TortoiseGit if you prefer to use a GUI instead of the command-line git tools. Version 2.1.0 and later should work fine.

Download Tools (Mac OSX)

C++14 compliant compiler: You need a working C++14 compiler. We tested tested XCode 10.0 with the Apple LLVM 10.0 compiler which can be downloaded for free. Newer versions should also be fine.

On Mavericks or above (OSX 10.9+):
  1. Installing XCode from the Mac App Store is optional

  2. Install the standalone Command Line Tools package:

    xcode-select --install

This command will open a GUI window (do not run this over SSH).

Waf (Build System)

We use the Waf build system to build our libraries, examples and unit tests. Waf is a Python-based build system that supports a wide variety of use cases. You may read more about Waf at the project homepage:

A Waf project typically contains two types of files:

  1. The waf file is the actual build system executable. This binary file is not meant to be edited.
  2. Several wscript and wscript_build files: These files contain the project build information. You can think of it as a type of makefile written in Python.


See the waf build options by running python waf -h in your terminal.

Git Version Control System

Our projects can be downloaded with git. This version control system allows you to easily get new updates whenever a project is updated.


We are currently migrating our private repositories from to

  • The Kodo libraries are currently still hosted on GitHub so to access those you just need a GitHub account.
  • The Score libraries are hosted on GitLab with some dependencies hosted on Github. Therefore you will need an account on both platforms.

GitHub / GitLab accounts

Accounts for GitHub and GitLab can be created at:

  1. Sign up GitHub
  2. Sign up GitLab

GitHub / GitLab authentication

If you don’t want to type your GitHub or GitLab username and password when downloading our main libraries (and their dependencies), then we recommend using Git-over-SSH. It is easy to configure SSH authentication on all platforms following this GitHub guide or GitLab guide.

You don’t have to use a passphrase, and you can skip anything about the ssh-agent, because your key will be loaded automatically. If you are using Windows, then run these commands in Git Bash. We don’t recommend using “GitHub for Windows”, so don’t follow the Windows-specific guide (the generic guide is good for all platforms).

After adding your SSH key on GitHub, please make sure that the following login works for you:

ssh -T

And try the same thing on GitLab:

ssh -T

In both cases, you should get a short welcome message.


If you don’t want to configure SSH authentication on or you can also clone the repository using the https protocol.

Normally, you have to type your GitLab/GitHub username and password with https. On Windows, you can configure git to store your credentials with the following command:

git config --global credential.helper wincred
