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](https://libsdl.org/) and [SDL2_mixer](https://www.libsdl.org/projects/SDL_mixer/). All other dependencies are statically linked into the engine. The development libraries for Windows can be downloaded from their respective websites, Linux and macOS developers should compile and install from 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 your SDL2/SDL2_mixer folders somewhere nice! mkdir flibitBuild cd flibitBuild cmake -G "Visual Studio 10 2010" .. -DSDL2_INCLUDE_DIRS="C:\SDL2-2.0.10\include;C:\SDL2_mixer-2.0.4\include" -DSDL2_LIBRARIES="C:\SDL2-2.0.10\lib\x86\SDL2;C:\SDL2-2.0.10\lib\x86\SDL2main;C:\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. Including data.zip ------------ You'll need the data.zip file from VVVVVV to actually run the game! It's available to download separately for free in the [Make and Play](http://distractionware.com/blog/category/vvvvvv-make-and-play/) edition of the game. Put this file next to your executable and the game should run. This is intended for personal use only - our license doesn't allow you to actually distribute this data.zip file with your own forks without getting permission from us first. See [LICENSE.md](../LICENSE.md) for more details. (If you've got a project in mind that requires distributing this file, [get in touch](http://distractionware.com/email/)!) 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
