VSXu is generally developed under Linux, but now (since 0.6.0) you can develop equally well on Windows.
VSXu is built with CMake which means you can use any editor, but in terms of IDE's we recommend either QtCreator (Linux/Windows) or Visual Studio (Windows).
See the INSTALL file for more information.
Thank you for downloading!
