== Compiling ScummVM with Visual Studio under Windows ==
== Installing the needed software and libraries ==


Compiling ScummVM with Visual Studio is not an awfully hard task. It is however slightly more complicated than using MinGW. We guide you through the steps to make ScummVM compile with Visual Studio on this page.
In this page, we guide you through the steps to compile ScummVM with Visual Studio.


== Things needed ==
=== Visual Studio ===
Visual Studio 2008-2019
You can get the free Community version of Visual Studio [https://visualstudio.microsoft.com/vs/ here].
Professional Visual Studio versions are working fine too.


=== Visual Studio ===
When installing Visual Studio 2017 or later, make sure to select the "Desktop Development with C++" workload.
There exists a free Community version of Visual Studio [https://visualstudio.microsoft.com/ here] that can be used.
Professional Visual Studioversions are working fine too.


We do support older versions of Visual Studio too. However, on this page we focus on building ScummVM with Visual Studio. Building ScummVM with older Visual Studio 2008 can require additional work not described on this page.
Building ScummVM with Visual Studio versions older than 2008 will require additional work which is not described here.


=== Needed Libraries ===
=== Needed Libraries ===
ScummVM relies on third-party libraries to implement certain functionality. Some of these libraries are required, like for example SDL, others are optional, like for example libtheora. We supply a set of prebuilt libraries for Visual Studio 2015. These have been build on Windows 8.1 using the Visual Studio 2015 Community Edition. The libraries can be found [http://www.scummvm.org/frs/build/scummvm_libs_2015.zip here].
ScummVM relies on third-party libraries for common features, such as MP3 decoding. Some of these libraries, like SDL, are required, whereas others like libtheora are optional.
 
We supply a set of prebuilt libraries for Visual Studio 2015 and later, which can be found [http://downloads.scummvm.org/frs/build/scummvm_libs_2015.zip here].


=== Installing Libraries ===
These libraries have been built on Windows 8.1 using the Visual Studio 2015 Community Edition.
The easiest way to make Visual Studio find the supplied libraries is by using the environment variable "SCUMMVM_LIBS". We describe this method now.
To make it work you have to follow these steps:
* Unzip the library zip to a directory of your choice. For example, you can unzip them into "C:\Users\YourUsername\Documents\scummvm_libs_2015".
* Go to Control Panel -> Environment Variables and set up a new variable "SCUMMVM_LIBS" with a value of the path you extracted the zip in. It is important that you do point the variable to the folder containing the "bin", "include", and "lib" directories.


=== Manually Building Libraries ===
If you want to build libraries for use with Visual Studio yourself, please refer to the [[Compiling_ScummVM/Visual_Studio/Compiling_Libraries|instructions for compiling the libraries yourself]].

ScummVM uses a configure/Make based build system. We have a tool to generate Visual Studio project files from this build system. The first steep you need to take is building this tool called "create_project".

First, open the solution file "devtools\create_project\msvc\create_project.sln". Then simply build the solution. The project file should automatically assure that the resulting "create_project.exe" is copied to "dists\msvc". If not, you will have to copy it yourself.

Simply open the generated solution file in "dists\msvc\scummvm.sln". Now you can ask it to build the desired configuration. By default it will build a debug configuration which is ideal to hack on ScummVM.

'''IMPORTANT''': You'll need to copy the matching SDL.dll file to a location Windows picks up to run the resulting binary. The easiest way to do this is to place the SDL.dll file in the directory where scummvm.exe is. There are multiple SDL.dll files to choose from, depending on your build configuration. Simply pick the right one from the prebuilt libraries. For example, if you build a Win32 Debug configuration, you will need to use "libs/x86/Debug/SDL.dll".
'''IMPORTANT''': If you get errors about missing DLLs, you'll need to copy them to a location Windows picks up to run the resulting binary. The easiest way to do this is to place the DLL files in the directory where scummvm.exe is. There are multiple folders to choose from, depending on your build configuration. For example, if you build a Win32 Debug configuration, you will need to copy them from "SCUMMVM_LIBS\lib\x86\Debug" to "dists\msvc\Debugx86".
 
NOTE: Several people have had errors about structure packing under Visual Studio 2019. In such cases, you need to update [http://libsdl.org/download-2.0.php SDL2] with the latest version.


== Compiling without Console/Status Window ==
== Compiling with Console/Text Output ==


If you want to run ScummVM without the console Window being present by default, there are two things you need to do:
By default ScummVM is compiled as a Windows subsystem application with no console output. If you need the console, you can do one of the following:
* In the Project Options for the scummvm project, go to the Linker | System | SubSystem line, and change the /SUBSYSTEM:CONSOLE to /SUBSYSTEM:WINDOWS
* In the create_project command, add <code>--enable-text-console</code>.
* In the file backends/platform/sdl/win32/win32.cpp, change the parameter from true to false in the first line of OSystem_Win32::initBackend:
* In the Project Options for the scummvm project, go to the Linker | System | SubSystem line, and change the /SUBSYSTEM:WINDOWS to /SUBSYSTEM:CONSOLE
ConfMan.registerDefault("console", false);
