Qt IVI Generator is fully integrated in qmake to generate all or part of a project.
In it's simplest form, qmake can generate all the source code and the project only needs to configure the type of project to build.
For complex setups, you can combine generated code with application specific code to extend and use the generated code.
CONFIG += ivigenerator QT_FOR_CONFIG += ivicore !qtConfig(ivigenerator): error("No ivigenerator available") QFACE_FORMAT = frontend QFACE_SOURCES = example.qface QFACE_MODULE_NAME = myModule QFACE_OUTPUT_DIR = myOutputDir QFACE_ANNOTATIONS = annotation.yaml
The following qmake variables are available:
|QFACE_FORMAT||frontend (default), simulator_backend|
|QFACE_SOURCES||A single |
|QFACE_MODULE_NAME||Optional. The name of the module that is using the generated code.|
|QFACE_OUTPUT_DIR||The output folder where the generated code is placed. The default location is the current build folder.|
|QFACE_ANNOTATIONS||A list of additional annotation files in YAML format. For more information, see the Annotations Option.|
For more details on the generator's command line arguments, see Use the Generator.
Note: Since the
ivigeneratorhas specific system dependencies, it may not be available in all QtIviCore installation. In this case, the
ivigeneratorqmake feature is also not available and this can result in build errors.
In this case, use the following code snippet that makes sure the build stops and provides a meaningful error message:QT_FOR_CONFIG += ivicore !qtConfig(ivigenerator): error("No ivigenerator available")
The qmake integration also supports generating code that you can subsequently compile into a Qt module. Since this module needs to work more closely with Qt's module building system, it shouldn't be loaded using the
CONFIG variable, but using the
load() function instead. The
ivigenerator_qt_module feature replaces the
The following shows how you can integrate the QtIviVehicleFunctions module:
TARGET = QtIviVehicleFunctions QT = core core-private ivicore ivicore-private CONFIG += c++11 ivigenerator QT_FOR_CONFIG += ivicore !qtConfig(ivigenerator): error("No ivigenerator available") ... QFACE_MODULE_NAME = QtIviVehicleFunctions QFACE_SOURCES += ivivehiclefunctions.qface load(ivigenerator_qt_module)
In addition to the project file for the module library, the
sync.profile also needs to be changed, as it's used to call the
syncqt.pl script that generates the forwarding headers. Usually, the
sync.profile is setup to search for these headers in the source folders. Using
$out_basedir, you can also extend the script to search in the build folder.
... %modules = ( # path to module name map "QtIviVehicleFunctions" => "$basedir/src/ivivehiclefunctions;$out_basedir/src/ivivehiclefunctions" ); ...
