How to make QT produce executable for Windows on Mac?

Question

I'm writing my app on QT and I've produced a working version on my mac. How can make QT also compile an executable for windows?

Answer 1

Qt SOURCE is compatible to Windows, Mac, Linux, ARM and other platforms.

Qt BINARIES are platform-specific. You cannot compile an .exe on the Mac, and hope to run that binary .exe on Windows or Linux.

You'll need to cross-compile, or actually install the Qt SDK and compile on each target platform, for each different kind of .exe.
