Qt 5 Core Compatibility APIs▲
The Qt 5 Core Compat module contains the Qt 5 Core APIs that were removed in Qt 6. The module facilitates the transition to Qt 6.
Using the Module▲
Using a Qt module's C++ API requires linking against the module library, either directly or through other dependencies. Several build tools have dedicated support for this, including CMake and qmake.
Building with CMake▲
Use the find_package() command to locate the needed module component in the Qt6 package:
find_package(Qt6 REQUIRED COMPONENTS Core5Compat)
target_link_libraries(mytarget PRIVATE Qt6::Core5Compat)For more details, see the Build with CMake overview.
Building with qmake▲
To configure the module for building with qmake, add the module as a value of the QT variable in the project's .pro file:
QT += core5compatReference▲
