Misa 3f4df82583 Remove TinyXML-1 This removes the TinyXML source files, removes it from CMakeLists.txt, removes all the includes, and removes the functions FILESYSTEM_saveTiXmlDocument() and FILESYSTEM_loadTiXmlDocument() (use FILESYSTEM_saveTiXml2Document() and FILESYSTEM_loadTiXml2Document() instead). Additionally I've cleaned up the tinyxml2.h include in FileSystemUtils.h so that it doesn't actually include tinyxml2.h unnecessarily, meaning a change to TinyXML2 shouldn't rebuild all files that include FileSystemUtils.h.		2020-06-12 15:08:29 -04:00

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 development libraries for Windows can be downloaded from their respective websites, Linux developers can find the dev libraries from their respective repositories, and macOS developers should compile and install from source (including libogg/libvorbis/libvorbisfile).

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"

Note that on some systems, the SDL2_LIBRARIES list on Windows may need SDL2/SDL2main/SDL2_mixer to have .lib at the end of them. The reason for this inconsistency is unknown.

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 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 for more details. (If you've got a project in mind that requires distributing this file, get in touch!)

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
