SmokeQt6

SMOKE (Scripting Meta Object Kompiler Engine) bindings for Qt 6. This project generates language-independent introspection libraries that expose Qt 6 classes, methods, and enums through a flat C interface, enabling language bindings such as QtRuby, PerlQt, and CommonQt (Lisp) to call into Qt without hand-written wrapper code.

Supported Qt 6 Modules

Module	Library	Qt Component
QtCore	smokeqt6core	Core non-GUI classes
QtGui	smokeqt6gui	GUI primitives (images, fonts, painting)
QtWidgets	smokeqt6widgets	Desktop widget toolkit
QtNetwork	smokeqt6network	Networking (TCP, UDP, HTTP, SSL)
QtOpenGL	smokeqt6opengl	OpenGL integration
QtPdf	smokeqt6pdf	PDF rendering
QtPrintSupport	smokeqt6printsupport	Printing support
QtQml	smokeqt6qml	QML engine
QtQuick	smokeqt6quick	Qt Quick scene graph
QtQuickWidgets	smokeqt6quickwidgets	Embedding Quick in Widgets
QtSql	smokeqt6sql	SQL database access
QtSvg	smokeqt6svg	SVG rendering
QtWebChannel	smokeqt6webchannel	Web channel communication
QtWebEngine	smokeqt6webengine	Chromium-based web engine
QtWidgets	smokeqt6widgets	Widget toolkit
QtXml	smokeqt6xml	XML parsing

Optional/disabled modules: QtDBus, QtHelp, QtMultimedia, QtMultimediaWidgets, QtPositioning, QtScxml, QtSpatialAudio, QtTest, QtUiTools, Qt3DAnimation, Qt3DCore, Qt3DExtras, Qt3DInput, Qt3DLogic, Qt3DRender, QScintilla, Qwt.

Prerequisites

• CMake >= 3.22
• C++17 compiler (MSVC 2019+, GCC, or Clang)
• Qt 6 (6.x, tested with 6.11)
• smokegen — the SMOKE code generator (must be built first, expected at ../smokegen/)

Building

SmokeQt depends on smokegen, the code generator. Clone and build it so that its CMake config and binary are available:

mkdir build && cd build
cmake .. -GNinja -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=\path\to\install -DCMAKE_MSVC_RUNTIME_LIBRARY=MultiThreadedDLL -DSMOKE_QT_VERSION=6 -DQt6_DIR=\path\to\qt6\lib\cmake\Qt6 -DLLVM_DIR=\path\to\llvm\lib\cmake\llvm
ninja -j 6
ninja install

On Windows, run the cmake commands from an x64 Native Tools Command Prompt. The Visual Studio generator can be used instead of Ninja if preferred, but Ninja is recommended for faster incremental builds.
