ld returned 1 exit status

Question

This is the code that i'm trying to run:

#include <QApplication>
#include <QPushButton>

int main(int argc,char *argv[])
{
    QApplication app(argc,argv);

    return app.exec();
}

And this is the error that i'm getting:

:-1: error: collect2: ld returned 1 exit status

Answer 1

You have to close the application before rebuilding it.

Answer 2

If you read the error message carefully, you will see the problem.

...ld.exe: cannot open output file ...

The linker is trying to write the generated executable file (debug.exe) to disk, but is not allowed to (Permission denied). This is mostly due to the fact that the application you built is currently running.

Close it and rebuild the application.
