Description
Hi,
I'm switching my code from qt5 to qt6.
Right now it works on linux, cross compile for windows but not on my mac...
I've created a simple exemple here:
https://github.com/iltommi/MRE
the problem seems to come from a public slot returning a QList<double>
class my_app : public QApplication { Q_OBJECT public: my_app( int &argc, char **argv ): QApplication(argc, argv) {}; public slots: QVector<double> my_slot() { return QVector<double>(); }; };
I use qt from homebrew and g++12 also from homebrew.
I get this error at linking time (after demanglig):
Undefined symbols for architecture x86_64: "QMetaType::registerConverterFunction(std::function<bool (void const*, void*)> const&, QMetaType, QMetaType)", referenced from: bool QMetaType::registerConverterImpl<QList<double>, QIterable<QMetaSequence> >(std::function<bool (void const*, void*)>, QMetaType, QMetaType) in mocs_compilation.cpp.o "QMetaType::registerMutableViewFunction(std::function<bool (void*, void*)> const&, QMetaType, QMetaType)", referenced from: bool QMetaType::registerMutableViewImpl<QList<double>, QIterable<QMetaSequence> >(std::function<bool (void*, void*)>, QMetaType, QMetaType) in mocs_compilation.cpp.o ld: symbol(s) not found for architecture x86_64
I've set up cirrus-ci build here: https://cirrus-ci.com/build/5261966146011136
The error happens with both intel and M1
