Qt is a cross-platform application development framework for desktop, embedded, and mobile.

Status

• Windows on Arm support is available QT for Windows has enabled support for Arm architecture from Qt v6.2. Installers are available from the their official website.

  • You can install it easily using aqt (does not need a Qt account)
    ./aqt.exe install-qt windows desktop 6.5.0 win64_msvc2019_arm64

  • Binaries are hosted here for 6.2.0.

• Qt is still in technical preview Technical Preview for Windows Arm64. LTS Long term support is expected from Qt 6.5 (presently available in beta Qt 6.5 Beta Released , expected to launch March 20238.(Expected to be released in Sept 2024)

• Qt can be compiled with LLVM (clang-cl) and MSVC compiler. Qt 6.2 has a known issue when compiled with MSVC. Recommended to use Qt 6.3.1 and above if MSVC compiler is required.

• Currently, QT Technical Preview only provides cross compilation on x64 for WoA target.

• Qt 5.15 can be built from sources (no binary available) by applying this patch and instructions (uses jom instead of cmake for build). Note: For native compilation, no patch is needed (only for cross compilation).
