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".

More information can be found at the MinGW homepage


Things needed

MinGW and MSYS

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" section (apart from MinGW-5.0.0.exe, which is in the "Proposed" section).

Download the following:


The following are downloaded through the automated installer, but you can install them here to have everything ready:


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.


Check the "Installing MinGW and MSYS" section below for instructions on how to create your ScummVM compilation environment


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

Get the latest mpeg2dec release from this page, libmpeg2 is included there

  • zlib. You need the latest zlib source code.


Installing MinGW and MSYS

Both MinGW and MSYS need to be installed and working to compile ScummVM.


  • First, install MinGW through its automated installer.
  • Then, install MSYS. After installation, a new console window will appear, asking if you wish to proceed with the post install. Answer 'y' to that prompt. You will then be asked if you have MinGW installed. Answer 'y' to that and then type in the path of your MinGW directory using forward slashes (e.g. C:/MinGW). Make sure that there is no "make" utility in the MinGW bin folder, as this will clash with the make utility in MSYS. With the recent packages described in the section above, you shouldn't have that problem.
  • After both MinGW and MSYS are installed correctly, install MSYS DTK

[TODO: describe how to navigate through folders, which tools will be used]


Building the libraries

Now, we need to compile the required libraries and tools.


NASM

First of all, we need nasm. So unzip the nasm archive in a directory, copy "nasmw.exe" to "nasm.exe" (because some projects call one and others call the other) and include the folder it is stored in into your system path. To do this, go to Control Panel->System, Advanced tab->environment variables and edit the "PATH" variable in the system variables list, adding the folder where you placed the aforementioned files. Directories in the system path are split with a semicolon (;), e.g. "C:\MinGW\msys\1.0\bin;C:\MinGW\bin;C:\nasm". Alternatively, you can just copy both files in MinGW's bin directory, e.g. C:\MinGW\bin as this should be already in your system path

Changes to the PATH will be reflected on newly opened command prompts only, so if you got any open already, close them to avoid confusion


SDL

SDL is already compiled and needs no further changes, so we can skip the compilation step for it


After extracting the contents of the SDL archive in a folder, copy all the files in SDL's include folder in MinGW's include folder and all the files in SDL's lib folder in MinGW's lib folder. Also, copy SDL.dll and i386-mingw32msvc-sdl-config in MinGW's bin folder. Rename i386-mingw32msvc-sdl-config to sdl-config


Now, we need to setup SDL. Go to SDL's folder and type 'make install prefix=/mingw' (note the forward slash, since you are using MSYS).


zlib

Unzip the source code in a folder, open MSYS, go to the zlib folder and issue this command to compile the library: 

make -f win32/makefile.gcc

After compilation, copy zlib.h and zconf.h inside MinGW's include folder and libz.a inside MinGW's lib folder


You can do this using Explorer or by typing these commands in MSYS inside the zlib folder: 

cp -p libz.a /mingw/lib
cp -p zlib.h zconf.h /mingw/include


libogg

libogg should be compiled before libvorbis and libFLAC Unzip the libogg archive in a folder, open MSYS, go to the libogg folder and issue these commands to compile the library: 

./configure --disable-shared
make

When everything is compiled, copy the include\ogg folder inside MinGW's include folder. So, you should end up with an ogg folder in MinGW's include folder. Also, copy the src\.libs folder as-is inside MinGW's lib folder, and also copy the files from the src\.libs folder inside MinGW's lib folder (because ogg libraries are searched both in the lib and in the lib\.libs folder)


You can do this using Explorer or by typing these commands in MSYS inside the libogg folder: 

cp -p include/ogg /mingw/include
cp -p src/.libs /mingw/lib
cp -p src/.libs/* /mingw/lib


libvorbis

Unzip the libvorbis archive in a folder, open MSYS, go to the libvorbis folder and issue these commands to compile the library: 

./configure --disable-shared
make

When everything is compiled, copy the include\vorbis folder inside MinGW's include folder. So, you should end up with a vorbis folder in MinGW's include folder. Also, copy lib\.libs folder from libvorbis folder as-is inside MinGW's lib folder, and also copy the files from the lib\.libs folder from libvorbis folder inside MinGW's lib folder (because vorbis libraries are searched both in the lib and in the lib\.libs folder)


You can do this using Explorer or by typing these commands in MSYS inside the libogg folder: 

cp -p include/vorbis /mingw/include
cp -p src/.libs /mingw/lib
cp -p src/.libs/* /mingw/lib


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.
