Building

Prerequisites

• Visual C++ 2010 or newer
• CMake (for Dr. MinGW)
• 7-Zip (for unpacking MinGW)
• InnoSetup 5 (for building an installer)

Instructions

Third party dependencies are registered using git submodules, so you will need to either clone with the --recursive flag, or run git submodule update --init after cloning.

The build.cmd batch file will attempt to build Very Sleepy and its dependencies.

Alternatively, you can build Dr. MinGW using the thirdparty/drmingw_build_mingw.cmd batch file, then use the Visual Studio solution file (sleepy.sln) to build everything else.

Bug reports and feature requests are welcome as well -- please file them as GitHub issues.
