Prerequisites: What You Need Before Installing

Qt is just a library; it needs a compiler to work. On Windows, you have two main free options. You must install one of these before running the Qt installer if you want to write code immediately.

  1. MinGW (Recommended for beginners):
    • This is a minimal compiler for Windows.
    • Note: The Qt installer actually includes a compatible version of MinGW, so you can skip this if you want a simpler setup.
  2. Microsoft Visual C++ (MSVC) (Recommended for professional use):
    • You need to install Visual Studio Community (free).
    • Install the "Desktop development with C++" workload.
    • Advantage: Better performance and compatibility with Windows APIs.
