the code of in linux operating system,how dose I run in windows operating system

the examples written of in linux operating system,how dose I run in windows operating system?please explain.thanks.

If it is a Qt app that does not use any linux-specific system calls, then you rebuild it from source code using a compiler and linker that targets the Windows OS. (For example, install Qt Creator on a Windows box and build the project there).

You cannot run an executable built for linux under Windows, it has to be rebuilt from source code for Windows.
