Qt

Qt is a cross-platform C++ framework for GUI and application development. For the MSYS2 toolchain used below, see C++.

Deploy with windeployqt​

windeployqt collects the Qt DLLs and plugins an executable needs so it can run on a machine without Qt installed.

Open the Qt x.x x-bit for Desktop terminal, change into the folder with the compiled executable, and run:

windeployqt.exe .

Batch file example:

path=C:\Qt\6.5.2\mingw_64\bin
copy .\release\ForTest.exe .\ForTest
cd ForTest
windeployqt ForTest.exe

Build from source on Windows (MSYS2)​

Install with pacman (MSYS2 MINGW64)​

# Search for packages
pacman -Ss mingw-w64-x86_64-qt6
pacman -Ss mingw-w64-harfbuzz

pacman -S --needed mingw-w64-x86_64-qt6-static mingw-w64-x86_64-qt-creator mingw-w64-x86_64-clang mingw-w64-x86_64-gdb mingw-w64-x86_64-cmake

# If more DLLs are missing
pacman -S --needed mingw-w64-x86_64-editorconfig-qtcreator
pacman -S --needed mingw-w64-x86_64-qt-creator-devel

Configure​

Qt's own configure.bat selects a static or shared build:

# GCC
configure.bat -debug -static -static-runtime -confirm-license -opensource -platform win32-g++ -nomake examples -prefix "C:\temp\qt-6.5.3-static-mingw_64-debug" -j 8

# MSVC
configure.bat -static -prefix "C:\Qt-6.5.3-static" -confirm-license -opensource -debug-and-release -platform win32-msvc -nomake examples -nomake tests -plugin-sql-sqlite -plugin-sql-odbc -qt-zlib -qt-libpng -qt-libjpeg -opengl desktop -mp

Build and install​

cmake --build . --parallel
cmake --install .
if(QT_FEATURE_static STREQUAL "ON" AND WIN32 AND MINGW)
    set_property(TARGET harfbuzz::harfbuzz PROPERTY
    IMPORTED_IMPLIB ${harfbuzz_DIR}../../../libharfbuzz.dll.a)
