|Compiling with MinGW is more complicated to set up. It is recommended that you use [[Compiling_ScummVM/MinGW-w64|MinGW-w64]] or [[Compiling ScummVM/Docker|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".

All you need to do is:
* Download the precompiled libraries and the [http://www.libsdl.org/release/SDL-1.2.15-win32.zip latest SDL runtime library] - latest version is 1.2.15 at the time this was written, you can find the latest version [http://www.libsdl.org/download-1.2.php here]. Precompiled libraries:
** [http://sourceforge.net/projects/scummvm/files/build/scummvm-required-libs-mingw.zip/download Precompiled libraries]


== Installing MinGW and MSYS ==
* [https://github.com/fribidi/fribidi FriBiDi]. Optional, for bidirectional text in languages that need it (e.g. Hebrew)
** You need the latest FriBiDi source code ([https://github.com/fribidi/fribidi/releases/tag/v1.0.11 v1.0.11] at the time of writing).

** You need the latest liba52 source code ([http://liba52.sourceforge.net/files/a52dec-0.7.4.tar.gz v0.7.4] at the time of writing).
* 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


* [https://tls.mbed.org/ mbedTLS]. Optional, for cloud support.
** You need the latest mbedTLS source code ([https://github.com/ARMmbed/mbedtls/archive/v3.0.0.tar.gz v3.0.0] at the time of writing).

* [https://curl.se/ libcurl]. Optional, for cloud support.
** You need the latest libcurl source code ([https://curl.se/download/curl-7.80.0.tar.xz v7.80.0] at the time of writing).


In order to get MinGW properly working under Windows Vista, you need to do the following:
==== Precompiled libraries ====
Go to Control Panel->System, and click on "Advanced System Settings" to the left. Then click on "Environment variables" and on the bottom window ("System variables"), select the "Path" variable and edit it. This variable tells windows where to look for binaries when it can't find them in the current folder. You'll find a lot of directories there separated by semicolons.  
To ease the whole process, a package of all the needed precompiled libraries has been created.
 
All you need to do is:
Make sure that the MinGW bin directory is included in the path (e.g. C:\MinGW\bin), which should already be included there from the MinGW installer. Also, make sure that the libexec path is included too (e.g. C:\MinGW\libexec\gcc\mingw32\3.4.2), which is needed in Vista to get MinGW properly working
* Download the precompiled libraries and the [http://www.libsdl.org/release/SDL-1.2.15-win32.zip latest SDL runtime library] - latest version is 1.2.15 at the time this was written, you can find the latest version [http://www.libsdl.org/download-1.2.php here]. Precompiled libraries:
** [http://downloads.scummvm.org/frs/build/scummvm-required-libs-mingw.zip Precompiled libraries]
* Extract them to your MinGW directory (e.g. C:\MinGW)

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".

=== NASM ===
=== NASM ===


First of all, we need nasm. So unzip the nasm archive in a directory, and copy both files to MinGW's bin directory. Alternatively, you can include the folder you unzipped the files in 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".
Unzip the nasm archive in a folder, and copy both files to MinGW's bin directory.
 


Note that 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
=== pkg-config-lite ===


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


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 the 'include/SDL' folder to MinGW's include folder, copy all the files in the 'lib' folder to MinGW's lib folder and copy all the files in the 'bin' folder to MinGW's bin folder.
=== SDL1 ===


If you do wish to recompile SDL from source code, please note the following:
Unzip the SDL archive in a folder, open MSYS, go to the SDL folder and issue these commands to compile and install the library:
* Check that the libSDL source file src/main/win32/version.rc contains the correct version. This was incorrectly listed as v1.2.14 for the v1.2.15 release, needed an additional patch.
* Note the README [http://www.libsdl.org/extras/win32/mingw32/README.txt here], especially the need to include the DirectX development header and libraries from [http://www.libsdl.org/extras/win32/common/directx-devel.tar.gz here] to ensure that the "dsound" rather than the "waveout" / "winmm" fallback audio driver is used.


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


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

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:

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:
  • 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.

Then issue these commands to compile and install the library:

CPPFLAGS=-D_WIN32_WINNT=0x400 ./configure --disable-shared --prefix=/mingw --with-schannel --with-mbedtls --disable-pthreads --disable-ldap
make
make install


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.
