Runtime requirements¶

Windows 10 (version 1903 aka 19H1, or later), or Windows 11, either 32-bit or 64-bit.
macOS AMD/Intel or Apple Silicon (Big Sur 11.0 or higher).
Linux AMD/Intel 64-bit with glibc 2.27 or higher.
- You will need the following system tools installed:
  - tar, wget or curl, git, unzip
  - libssl-dev (Debian, Ubunutu) or openssl-devel (RedHat)
  - ninja (this requirement will be removed)
  - If any are missing you will be asked if DkCoder can install them the first time you run ./dk from the command line.
- For graphics you will need one of:
  - X11 with a direct OpenGL driver.
    - A good prereq test is running glxgears (ex. yum install glx-utils; glxgears). If that works, DkCoder graphics should work.
    - Don't expect the LIBGL_ALWAYS_INDIRECT=1 environment variable to work. That is sometimes recommended when forwarding X11 with ssh -X or into a Docker container, but it forces the protocol to be a too-old OpenGL version 1.4 .
  - Wayland. Set the environment variable SDL_VIDEODRIVER=wayland to force it.
  - Linux Direct Rendering Manager. If supported, you will have a /dev/dri/card0. Set the environment variable SDL_VIDEODRIVER=kmsdrm to force it.
- That's it. Linux desktops are complex!

Runtime system¶

The dk executable and ./dk wrapper script are the primary coding tools for DkCoder.

With dk or ./dk, your scripts will have access to the following libraries:
