Compiling ScummVM/MinGW
Compiling ScummVM with Minimalist GNU for Windows (MINGW)
MinGW is "a collection of freely available and freely distributable Windows specific header files and import libraries combined with GNU toolsets that allow one to produce native Windows programs that do not rely on any 3rd-party C runtime DLLs".

Things needed
MinGW
To download MinGW, visit its download page
Downloading MinGW for the first time can be a daunting task, as there are a lot of packages to download. The ones you need are in the "Current" tab (apart from MinGW-5.0.0.exe, which is in the "Proposed" section).
Download the following:
- The MinGW automated installer 5.0.0
- MSYS 1.0.10
- binutils
- gcc-core
- gcc-g++
- mingw32-make
- msysDTK
- mingw-runtime 3.8 (downloaded automatically) OR mingw-runtime 3.9 (the current version)
- w32api 3.3 (downloaded automatically) OR w32api 3.5 (the current version)
Note that the above downloads are the current ones, and can change in the future. To get the latest versions (if one of the links above is broken), visit the MinGW download page and download the latest versions there. The latest packages for MinGW (but not MSYS) can be downloaded through the automated installer MinGW-5.0.0.exe.
Libraries needed
You need the file SDL-devel-1.2.9-mingw32.tar.gz (1.2.9 is the latest version at this time)
Note that the libraries included in the "vorbis" package won't work. You need libogg and libvorbis, not vorbis
- libmad for MP3 support
- libmpeg2 for MPEG-2 support
Get the latest mpeg2dec release from this page, libmpeg2 is included there
- zlib. You need the latest zlib compiled DLL
If you wish to compile zlib statically in ScummVM (so that zlib1.dll is not needed), you'll also need the zlib source code.
Building the libraries
Now, we need to compile the required libraries.
[TODO]
NASM
[TODO]
SDL
SDL is already compiled and needs no further changes, so we can skip the compilation step for it
zlib
zlib is already compiled, so we can skip the compilation step for it
[TODO]
libogg
[TODO]
libvorbis
[TODO]
mpeg2dec
[TODO]
After you compile this one, go to its include directory, create a folder "mpeg2dec" in there and copy all files from the include folder in this subfolder. So you should end up with 2 directories, "include" and "include\mpeg2dec" with the same files. This is needed, as ScummVM includes files from the "mpeg2dec" directory

Ready to go!
OK this should be all of it (thankfully), so you should be good to go.
