Compiling ScummVM/Visual Studio
Compiling ScummVM with Visual Studio under Windows
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.
Things needed
Visual Studio
There exists a free Community version of Visual Studio 2015 here that can be used. Professional Visual Studio 2015 versions 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 2015. Building ScummVM with older Visual Studio versions can require additional work not described on this page.
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 here.
Installing Libraries
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 instructions for compiling the libraries yourself.
Preparing the Project Files
Building create_project
ScummVM uses a configure/Make based build system. We feature 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\msvc14\create_project.sln". Then simply build the solution. The project file should automatically assure that the resulting "create_project.exe" is copied to "dists\msvc14". If not, you will have to copy it yourself.
Generating the Project Files
Simply run the batch script "dists/msvc14/create_msvc14.bat". It will guide you through configuring ScummVM.
IMPORTANT: You will have to re-generate the project files whenever new source files have been added to or removed from the configure/Make based build system. When you add new files to ScummVM, you will have to add them to the respective "module.mk" file to assure ScummVM still builds fine with the configure/Make based build system.
Compiling ScummVM
If you followed all the steps, you are now ready to compile ScummVM with Visual Studio. Congratulations!
Simply open the generated solution file in "dists\msvc14\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".
Compiling without Console/Status Window
If you want to run ScummVM without the console Window being present by default, there are two things you need to do:
- 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 file backends/platform/sdl/win32/win32.cpp, change the parameter from true to false in the first line of OSystem_Win32::initBackend:
ConfMan.registerDefault("console", false);
