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

* 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.

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.
