Updated after 0.62 release. These are probably not very build friendly at the moment. I will make them a bit more user friendly in the future. In order to build these... You need visual studio 2003. There are no VC6 files or VS2002 files. In theory you should be able to create VC2002 files... and in fact out of date VC2002 files are generally found with .vcproj.bak extensions. However some of the libraries will not build in VS2002, there is a bug in the 2002 compilers imlpementation of mixed mode dlls, which stops some of the .NET bridging libraries linking. You need NASM for FLAC to build. (lifes easier if it's at C:\NASM) you'll have to play around with that yourself... it's a real pain ! Also the vcproj files have hidden settings that don't show up in visual studio... you'll have to figure it out (ie edit the vcproj) I suggest once you get it to build, leave it built... don't clean that project. The clean script it has for some reason tries to delete some necessary header files. Don't ask me why ! Also ignore visual studio hassling you about sourcesafe for flac. I've been using NASM 0.98.38 which you can find here http://sourceforge.net/projects/nasm You want the win32 binaries. If you do accidentally clean FLAC, you will get a message when you try to build that says "ordinals.h" not found. You need to go to the libFLAC directory and find the file called ordinals.h.bak and *copy* it to the same directory without the .in extension. Don't just rename it... you want to keep that file for next time this happens ! You need DirectX 9 SDK installed (lifes easier if it's at C:\DXSDK) Otherwise all projects prefixed with dsf you'll need to change the absolute references to that path. I'll try to do something to make this easier in future. If the baseclasses project shows up as not found, you need to find it in the DXSDK directory tree, and load it from there. By default it tries to build against Multithreaded static runtimes You *must* change these to Multi Threaded DLL or Multi Threaded debug DLL. Otherwise all sorts of chaos will occur. This project is not part of the package. It is part of the DirectX SDK. If you try to build the installer project, you need to change the paths of the AUTHORS, COPYRIGHTS etc files... i can't make it accept a relative path. Probably other stuff i can't think of. These aren't really ready for easy use yet.
