QList of Custom Objects

I am trying to create a QList of custom objects, but am unable to do so. The compilation error I receive when trying to do so is:

error: symbol(s) not found for architecture x86_64 (file not found)

I am able to create a QList of pointers of custom objects, as well as that of primitive data types. I know QList supports doing what I am trying to do, as it says so in the documentation.

I am using Mac OS X 10.7.5, Qt 5.0.1, and Qt Creator 2.6.2.

Code:

QList<MyClass> my_list;

According to the documentation: QList's value type must be an assignable data type.

To qualify, a type must provide a default constructor, a copy constructor, and an assignment operator. So your custom class should be implemented like this.

class MyClass
 {
 public:
     MyClass() {}
     MyClass(const MyClass &other);

     MyClass &operator=(const MyClass &other);

 private:
     //private data members
 };
