How to install Lua and LuaJIT on Windows

How to install Lua and LuaJIT on 64-bit Windows

  1. Download the latest Lua and LuaJIT sources

    • Create temporary folder for Lua sources.
      I assume you would use C:\Temp\ folder.

    • Visit Lua FTP webpage and download the latest Lua source archive, currently it is lua-5.4.3.tar.gz

  • Use suitable software (7-Zip, WinRar, WinZip or TotalCommander) to unpack the archive.

How to build windowless Lua for Windows

What is "windowless Lua"?

Windowless Lua does not create a console window.
It runs invisible for user.

Please note that "windowless" means "doesn't have stdin, stdout and stderr".
You will not be able to see error message.
io.read(), io.write() and print() in your Lua script will not work.
But in some situations invisible Lua is just what you need very much.
For example, to avoid a GUI application (especially a game) to lose input focus when some background Lua script is started.
