Compiling ScummVM/MinGW

NOTE

Compiling with MinGW is more complicated to set up. It is recommended that you use MinGW-w64 or Docker instead, which are far easier to set up and get working.

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. See also MinGW-w64.

Precompiled libraries

To ease the whole process, a package of all the needed precompiled libraries has been created. All you need to do is:

• Download the precompiled libraries and the latest SDL runtime library - latest version is 1.2.15 at the time this was written, you can find the latest version here. Precompiled libraries:
  • Precompiled libraries
• Extract them to your MinGW directory (e.g. C:\MinGW)

MSYS primer

From the developer's webpage: "MSYS or Minimal SYStem is a POSIX and Bourne shell environment use with MinGW. It provides a hand picked set of tools to allow a typical configuration script with Bourne syntax to execute. This allows most of the GNU packages to create a Makefile just from executing the typical configure script which can then be used to build the package using the native MinGW version of GCC".

MSYS commands can be confusing for people using Windows, as MSYS emulates a Bourne shell environment, which is found in most Unix/Linux distributions. The available commands can be viewed by typing "help" in the command prompt. Help on a specific command is available by typing "help" followed by the command, e.g. "help alias".

Note that MSYS uses forward slashes between folder names, not backward slashes, as is the case with Windows. Additionally, some special characters like the space need to be escaped with a backward slash("\"). Drives are mounted to folders, so drive "C:" would be under folder "/c". Therefore, to switch to directory:

C:\Program Files\Test Folder

we would switch to:

/c/Program\ Files/Test\ Folder

The basic commands you'll need are:

cd - changes the current drive and directory
pwd - shows the current drive and directory
ls - lists files in a folder
make - makefile, used to compile projects
strip - remove debug information from executable files

Note that if you wish to run a file from the current folder, you need to specify it before the file name, i.e. if you wish to run "test" from the current folder, you should type:

./test

Building the libraries

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

NASM

Unzip the nasm archive in a folder, and copy both files to MinGW's bin directory.

pkg-config-lite

Unzip the pkg-config-lite archive in a folder, and copy the "bin" and "share" to MinGW's root directory.

SDL1

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

./configure --disable-shared --prefix=/mingw
make
make install

Note the README here, especially the need to include the DirectX development headers from here to ensure that the "dsound" rather than the "waveout" / "winmm" fallback audio driver is used.

SDL2

Note that a prebuilt version of SDL2 is required since MinGW32 doesn't have all the necessary Windows SDK headers.

Unzip the SDL2 archive in a folder, open MSYS, go to the SDL2 folder and issue this command to install the library:

make install-package arch=i686-w64-mingw32 prefix=/mingw

libogg

libogg should be compiled before libvorbis, libtheora and libFLAC.

Compiling ScummVM

To compile ScummVM, issue the following commands inside the scummvm folder (where Makefile resides):

./configure
make

After compilation, you'll end up with a very big scummvm.exe (around 16MB). This is because debug symbols and information are embedded by default in the exe file, making it very big. To remove all the unneeded debug information from the executable, thus reducing its size by about 12MB, go to the folder where the compiled scummvm.exe file is and run the following command:

strip scummvm.exe

Compiling with Console/Text Output

By default, ScummVM now compiles with console output. If for some reason you do NOT want console output (which was the default behavior until recently), use the following flag when running the configure script:

./configure --disable-windows-console

Compiling with Windows 95/98/ME support

By default, ScummVM builds using this method require Windows XP or later. If you want compatibility with older versions of Windows, use the following commands to compile ScummVM:

SDL_CONFIG=sdl-config ./configure --disable-windows-unicode --disable-flac --disable-libcurl
make

Ready to go!

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