'''We do not support building in this way''', but if you want to use it, instructions are below.
'''We do not (officially) support building in this way''' and we don't recommend using this method if you want to distribute your ScummVM builds.
 
However, we offer preliminary support for the MSYS2/MinGW-w64 toolchain. Feel free to contact me (rootfather) either via eMail or IRC if you have questions regarding MSYS2/MinGW-w64.


Our officially supported MinGW build instructions are at [[Compiling_ScummVM/MinGW]].

==== Download and install the mingw-w64 compilation toolchain====
==== Download and install the necessary packages ====
In the MSYS2 terminal, type:
The MinGW packages are named mingw-<env>-<package>, where <env> is either x86_64 or i686, depending on your architecture (64-bit and 32-bit, respectively).
<source lang="bash">
$> pacman -S mingw-w64-<env>-toolchain
</source>
where <env> is either x86_64 or i686, depending on your architecture (64-bit and 32-bit, respectively).


This command will fetch and install the packages needed for compiling, including (but not limited to) GCC 5.x, GDB, and libwinpthread-git.
To create an i686 or x86_64 build environment, we need to first update the already installed packages and the MSYS2 environment itself.
To do that, type the following in the MSYS2 terminal:
<syntaxhighlight lang="bash">
pacman --noconfirm -Sy
pacman --needed --noconfirm -S bash pacman pacman-mirrors msys2-runtime
</syntaxhighlight>


==== Install make ====
For i686 (32-bit), type the following in the MSYS2 terminal to automatically install all packages/libraries needed to compile ScummVM:
ScummVM uses Makefiles to build the project. Makefiles are build configuration files that the compiler uses to compile, link and solve dependencies. "make" is the software that runs the Makefiles.
<syntaxhighlight lang="bash">
pacman -S --needed --noconfirm base-devel git mingw-w64-i686-{a52dec,curl,faad2,freetype,flac,fluidsynth,libjpeg-turbo,libogg,libvorbis,libmad,libmpeg2-git,libtheora,libpng,nasm,readline,SDL2,SDL2_net,toolchain,winsparkle,zlib}
</syntaxhighlight>


MSYS2 does not support make out of the box, but it has its own implementation. Install it by typing:
For x86_64 (64-bit), type the following in the MSYS2 terminal to automatically install all packages/libraries needed to compile ScummVM:
<syntaxhighlight lang="bash">
pacman -S --needed --noconfirm base-devel git mingw-w64-x86_64-{a52dec,curl,faad2,freetype,flac,fluidsynth,libjpeg-turbo,libogg,libvorbis,libmad,libmpeg2-git,libtheora,libpng,nasm,readline,SDL2,SDL2_net,toolchain,winsparkle,zlib}
</syntaxhighlight>


<source lang="bash">

$> pacman -S make

=== Install the needed libraries ===
=== Install the needed libraries ===
In order to compile properly, ScummVM needs you to have certain libraries installed. All the libraries in the list can be installed with similar commands:
<source lang="bash">
$> pacman -S mingw-w64-<env>-<library>
</source>
where <env> is the environment as previously stated, and <library> is the name of the library, as stated in the list (e.g. pacman -S mingw-w64-x86_64-SDL):


* '''SDL''' Mandatory.
''You only have to install the libraries manually if you prefer not to use the automated way in the section above. For most users, installing all packages automatically will just work fine.''
 


* '''nasm''' Optional, for faster compile of scalers.

To do that, just open a MSYS2 console, [http://gvsigce.sourceforge.net/wiki/index.php/Getting_started_with_MSYS#Navigating_the_file_system navigate] to the source folder where you have cloned scummvm.git, and type the following commands:

If everything went well, you should have a big executable in the compilation folder, named scummvm.exe. The size of the executable comes from the debug symbols embedded in the file, so you can run the following command to shrink it:
