Qt is a cross-platform application development framework for desktop, embedded, and mobile.
Status
Windows on Arm support is available from Qt v6.2. Installers are available from the official website.
Qt is still in technical preview for Windows Arm64. LTS expected from Qt 6.5 (presently available in beta Qt 6.5 Beta Released , expected to launch March 2023)
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.
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).
Build from Source
Qt official documentation to build from source including dependencies required: https://wiki.qt.io/Building_Qt_6_from_Git
Install MSYS2 build dependencies:
pacman -S mingw-w64-x86_64-headers-git
Main commands to build from source on a windows arm64 machine
git clone https://code.qt.io/qt/qt5.git qt6 cd qt6 perl init-repository mkdir qt6-build cd qt6-build ..\configure.bat -prefix C:\path\to\install cmake --build . cmake --install .
Binary Availability
Binary with Arm64 support is available at https://doc.qt.io/qt-6/windows.html
