How to Build

VVVVVV's official desktop versions are built with the following environments:

  • Windows: Visual Studio 2010
  • macOS: Xcode CLT, currently targeting 10.9 SDK
  • GNU/Linux: CentOS 7

The engine depends solely on SDL2 and SDL2_mixer. All other dependencies are statically linked into the engine. The libs for Windows are in this repository, all other platforms should install them either from the OS package manager or from self-compiled source.

Steamworks support is included and the DLL is loaded dynamically, you do not need the SDK headers and there is no special Steam or non-Steam version. The current implementation has been tested with Steamworks SDK v1.46.

To generate the projects on Windows:

# Put the SDL2/SDL2_mixer VC development libraries next to the VVVVVV folder!
mkdir flibitBuild
cd flibitBuild
cmake -G "Visual Studio 10 2010" .. -DSDL2_INCLUDE_DIRS="../../SDL2-2.0.10/include;../../SDL2_mixer-2.0.4/include" -DSDL2_LIBRARIES="../../SDL2-2.0.10/lib/x86/SDL2;../../SDL2-2.0.10/lib/x86/SDL2main;../../SDL2_mixer-2.0.4/lib/x86/SDL2_mixer"

To generate everywhere else:

mkdir flibitBuild
cd flibitBuild
cmake ..

macOS may be fussy about the SDK version. How to fix this is up to the whims of however Apple wants to make CMAKE_OSX_SYSROOT annoying to configure and retain each time Xcode updates.

A Word About Compiler Quirks

This engine is super fussy about optimization levels and runtime checks. In particular, the Windows version absolutely positively must be compiled in Debug mode, with /RTC enabled. If you build in Release mode, or have /RTC disabled, the game behaves dramatically different in ways that were never fully documented (bizarre softlocks, out-of-bounds issues that don't show up in tools like Valgrind, stuff like that). There are lots of things about this old code that could be cleaned up, polished, rewritten, and so on, but this is the one that will probably bite you the hardest when setting up your own build, regardless of platform.

We hope you'll enjoy messing with the source anyway!

Love, flibit
