Re: Can't pass a signal with QSharedPointer (or std::shared_ptr<>) between threads
hi
the program is this:
#include <QCoreApplication>
#include <iostream>
#include <memory>
#include <QObject>
#include <QMetaType>class Student : public QObject
{
Q_OBJECTpublic:
void printOrder()
{
emit calledtoPrint();
}signals:
void calledtoPrint();
};
Q_DECLARE_METATYPE(Student)class Printer : public QObject
{
Q_OBJECT
//uncrustify off
public slots:
//uncrustify on
void print()
{
std::cout << " print the request" << std::endl;
}
};
Q_DECLARE_METATYPE(Printer)
int main(int argc, char* argv[])
{
QCoreApplication a(argc, argv);std::shared_ptr<Student> std = std::make_shared<Student>(); std::shared_ptr<Printer> print = std::make_shared<Printer>(); QObject::connect(std.get(), &Student::printOrder, print.get(), &Printer::print); std::cout << "Program start " << std::endl; std->printOrder(); return a.exec();}
@nasimChildOfDesert Please post the actual error.

it doesnt build and show this:

The actual error should be somewhere wbove that line. Please post it... -

@jsulm
you know , when i build my program it show this error .
i send all of the code.did you see that? -

This is not the error: :-1: error: [CMakeFiles/signalSlotsharePtr_autogen.dir/build.make:58: CMakeFiles/signalSlotsharePtr_autogen] Error 1
It just tells you that there was an error. The error message must be ABOVE that line... -

This is the error and it also tells you what you should do to fix it:
Consider to add #include "main.moc" enable SKIP_AUTOMOC for this fileIt is better to define QObject based classes in their own header and cpp files.
