Cataclysm: Bright Nights

Compiler Support

Our goal with compiler support is to make it as easy as possible for new contributors to get started with development of the game, while also using the newest compilers (and thus language standards) that we can.

To that end, we aim to support gcc and clang up to the newest stable versions and back to those shipping in any supported version of a popular distribution or relevant development environment, including Ubuntu, Debian, MSYS, and XCode.

In practice, compiler support is often determined by what is covered in our automated testing.

At time of writing, the oldest relevant compiler is gcc 5.3, shipped in the Ubuntu Xenial LTS release. Ubuntu is likely to remain the limiting factor, so the set of supported compilers should be reviewed when Xenial ceases support in 2021-05.


We support and test gcc from version 12.


We support and test Clang from version 14.

Mingw and Mingw-w64

We use Mingw for cross-compilation of Windows versions on Linux. gcc 5.4 is currently used both in the tests and for the Windows release binaries.


MSYS2 is a way to build the project on Windows. It currently offers gcc at versions 7 or higher.

MSYS also provides clang. We don’t currently support using clang here, but work to that end is welcome.

Visual Studio

We also support Visual Studio 2015 Update 3 and above.
