== Instructions for compiling the needed libraries for Visual Studio yourself ==
=== Libraries needed ===Building libraries for use with Visual Studio is a complicated process. Many libraries only feature out-dated project files or have incompatible configurations for their project files. On this page we give a general introduction of the settings we used for building the libraries with Visual Studio 2015 Community Edition. Afterwards, we give a more detailed view on the process of building each invidiual library.
We used the following settings when compiling the libraries:* [httpRun-Time Library://www.libsdl.org/downloadWe use the "Multi-Threaded DLL" run-1time library.2.php SDL 1.2], file SDLFor Debug configurations we use the "Multi-devel-1Threaded Debug DLL" (option "/MDd").2.XXFor Release configurations we use the "Multi-VC8.zip Threaded DLL" (where XX is the current release numberoption "/MD").Latest stable version at the * Link-time of writing thisCode Generation: [httpWe disable LTCG for all configurations (option "/LTCG://wwwOFF").libsdl.org/release* Whole Program Optimization: We disable WPO for all configurations (option "/SDLGL-devel-1").2.14-VC8.zip 1.2Please assure that any libraries you build use exactly the same configuration settings.14]

== Building We used a custom project file when building zlib to get the libraries ==old standard library name "zlib.lib". It can be found inside a zip file in the "patches/" directory of our pre-built library package. The project file was created for zlib 1.2.8.
Now, we need to compile the required libraries.=== libogg ===
Note that you'll need We use the "libogg_static" solution to build all libraries with the same configuration settings (debug or release). If you don't need create a specific library, you can remove it from your build by going to Project->Properties, Configuration Properties->C/C++->Preprocessor and remove the "USE_XXX" directive for that library from there. For example, to remove OGG support, remove the USE_VORBIS directivestatic linking.
Also, make sure to disable the inclusion of default libraries in all libraries. You can do this from the project properties->Librarian->General and setting "Ignore all default libraries" to "Yes (/NODEFAULTLIB)" (special thanks to nolange for this tip). Finally, make sure that optimization is set to "Maximize speed" (or anything other than "Full optimization"), otherwise it will be impossible to build incremental debug builds later on (you'll get a warning saying "ignoring '/INCREMENTAL' due to '/LTCG' specification"). You can do this from the project properties->C/C++->Optimization, and set "Optimization" to "Maximize Speed (/O2)"=== libvorbis ===
You will need to use the "vorbis_static" solution. It should feature working x86 (Win32) and x64 (x64) targets by default.
=== A note about VS2008/2005 ==='''Note''': You need to assure that the headers (and libraries in case you build a dynamically linked libvorbis) of libogg are in the paths MSVC searches.
If you're building the libraries with VS2008/2005, you will get ''Note''': The static solution can be bugged and produce a lot of deprecation warningslibrary named "libvorbisfile. These are normal and nothing to worry about, they're just Microsoft's way lib" instead of saying "This is a bad code practicelibvorbisfile_static. Use this insteadlib". It's not easy to turn these off without several modifications You will need to fix the target name in the code, so just ignore themproject settings.
Read more here'''Note''': You'll need vorbis, vorbisfile and also vorbisenc for ScummVM tools.
http://msdn.microsoft.com/msdnmag/issues/05/05/SafeCandC/ === libtheora ===
http://wwwYou will need to use the "libtheora_static" solution.gamedev.net/community/forums/topic.asp?topic_id=361433
http'''Note'''://blogsThe static solution can be bugged and produce a library named "libtheora.msdnlib" instead of "libtheora_static.com/oldnewthing/archive/2005/01/07/348437lib". You will need to fix the target name in the project settings.aspx
If you do wish to make them disappear, you need to include on top the main function of each library, before the includes, the following lines: === libmad ===
#if (_MSC_VER >= 1400) /* VC8+ (VS2005) */ #pragma warning(disable : 4996) /* Disable all deprecation warnings */ #endif /* VC8+ (VS2005) */You can use the "libmad" solution.
'''Note for x64:''' When you want to build a x64 library for libmad you will need to create your own x64 config for it. You can do so by easy conversion of the existing libmad solution files for x86. For Release mode you will also need to edit the preprocessor definitons via: Properties -> Configuration Properties -> C/C++ -> Preprocessor -> Preprocessor Definitions: there you will need to replace "FPM_INTEL" with "FPM_64BIT".
=== NASM ===You will also need to apply the following patch to mad.h:
First of all, we need nasm. So unzip the nasm archive in a directory, copy "nasmw.exe<syntaxhighlight lang=" to diff"nasm.exe" (because some projects call one and others call the other) and include it in the executable path of VS. To do this, go to Tools>->Options->Projects and solutions->VCmad.h Tue Nov 03 18:29:06 2009+++ directoriesmad.

=== FLAC ===
=== SDL === SDL is already compiled Open the FLAC solution and needs no further changes, so we can skip the compilation step for it. '''Note for x64''': You will need to compile SDL for x64 on your own (as of the time of this writing), to do so you will also need to install the [http://msdn.microsoft.com/en-us/directx/default.aspx DirectX SDK found here]. You will also need to apply this patch [http://robertmegone.com/scummvm/build/sdl.patch from here] (patch gladly taken from the SDL mailing list). After adding a new x64 configuration option in the project files, you may also need to remove "/MACHINE:I386libFLAC_static" as additional linker command in Project->Properties, Configuration Properties->Linker->Command Line. === zlib === You'll need the zlib source package. After unzipping it, go into the projects directory in the zlib source and open the solution under projects\visualc6. Right click on the "zlib" project, and go to its properties. Then, go to Configuration Properties->C/C++->Code Generation and change the Runtime library from "Multi-Threaded DLL (/MD)win_utf8_io_static" to "Multi-Threaded (/MT)" (if you don't do this step, you'll have issues compiling ScummVM later on). Then, compile the "zlib" project using the LIB release configuration
=== libogg libfaad ===
Compile this first, as many other libraries need it. Go We used the following patch when compiling libfaad to adjust for changes in the win32 directory and build the "libogg_static" solution of your MSVC version (which should be found in one of the sub-directories). The solution should feature working x86 (Win32) and x64 (x64) targets by default, so you can compile either of those depending on whether you decide to build an x86 or x64 ScummVM.runtime:

'''Notefor x64:''': When you do not include your ogg headers/libraries in your global MSVC path settings want to build a x64 library for libfaad you will need to do the following: include the libogg include and library paths in VScreate your own x64 config for it. To You can do this, go to Tools->Options->Projects and solutions->VC++ directories and include the include directory so by easy conversion of libogg as well as the directory with the compiled ogg library. You'll need vorbis, vorbisfile and also vorbisenc existing libfaad solution files for ScummVM toolsx86.
=== libmpeg2 ===
The VC6 solution files (inside the vc++ folder) need to be We used for this library, but first they all need to be changed to DOS format, otherwise Visual Studio will complain that the project files are corrupted. Then, open file config.h inside the vc++ folder and comment out the following line, near the end of the file: #define restrict __restrictOpen the solution and compile project "libmpeg2". After you compile it, go to its include directory, create a folder "mpeg2dec" in there and copy all files from the include folder in this subfolder. You will end up with 2 directories, "include" and "include\mpeg2dec" with the same files. This is needed, as ScummVM includes files from the "mpeg2dec" directory   === libmad === Open and compile the "libmad" custom solution '''Note for x64:''' When you want to build a x64 library for libmad you will need to create your own x64 config for it. You can do so by easy conversion of the existing libmad solution files for x86. For Release mode you will also need to edit the preprocessor definitons via: Properties -> Configuration Properties -> C/C++ -> Preprocessor -> Preprocessor Definitions: there you will need to replace "FPM_INTEL" with "FPM_64BIT". You will also need to apply the following patch to mad.h: [http://robertmegone.com/scummvm/build/mad.patch mad.patch] === FLAC === Open its solution and compile the libFLAC_static project. By default, optimization for this library is set to "full" in release builds, which will prevent you from performing incremental debug builds later on, so make sure to set it to "Maximize speed" (or anything other than "Full optimization"), otherwise it will be impossible to build incremental debug builds later onlibmpeg2. Check the introductory section for more information. Also, FLAC OGGs are not needed, so support for these It can be dropped by going to the libFLAC_static project settings and removing the FLAC__HAS_OGG switch from C/C++->Preprocessor->Preprocessor Definitions. '''Note for x64''': After converting the Win32 target to x64 you will need to adapt some found inside a zip file settings. First of all you will need to disable all *.nasm files in the "libFLAC_static" project, this can be easily done by right clicking on them and selecting "Properties", now set "Excluded From Build" to "true". Next you will need to adapt the Preprocessor Definitions: First of all remove the following defintions: "FLAC__CPU_IA32", "FLAC__HAS_NASM" and "FLAC__USE_3DNOW", now also add "FLAC__NO_ASM". Last but not least you will need to apply the following patch file to "bitreader.c" of the "libFLAC_static" project: [http://robertmegone.compatches/scummvm/build/flac.patch flac.patch] === libpng === Open the solution under projects\visualc71. You also need zlib to compile this library, which must be placed in a folder named "zlib" outside libpng's directory. You need to change the settings of zlib like you have done before (iour pre-built library package.eThe project file was created for libmpeg 0. from "Multi-Threaded DLL (/MD)" to "Multi-Threaded (/MT)")5. Check the zlib section for more information1.
