Compiling errors after loading old project

[Dy3zz]

I reinstalled my virtual machine and tried to load my Qt project. But the problem is that i receive some errors that i didnt have before.
I let a scressshot of the errors below:

This is the .cpp file. The header is the next:

#ifndef PROJECTVIEW_H
#define PROJECTVIEW_H

#include <QWidget>

namespace Ui {
class projectview;
}

class projectview : public QWidget
{
    Q_OBJECT

public:
    explicit projectview(QWidget *parent = nullptr);
    ~projectview();

private:
    Ui::projectview *ui;
};

#endif // PROJECTVIEW_H

Either rename your form in the designer or use the correct ui class name in your class.

[Christian Ehrlicher]

You don't include the header (ui_projectview.h I would guess) where the class Ui::projectview is defined.

As @Christian-Ehrlicher says, and you would have had same problem whenever you last saved this file as you show above.

I added the header but I received the same error:

Then look into the header and see if the class name is correct.

@Christian-Ehrlicher I put the header code in the initial question. It seems to be good for me

@Dy3zz Are those real build errors (so, when you build) or just errors from code model in QtCreator?

[Dy3zz]

@jsulm They shows up when i build the project

@Dy3zz
The question is not what you have in projectview.h but what you have (near the end of) the generated ui_projectview.h file.

What you are supposed to see there is:

namespace Ui {
    class projectView: public Ui_projectView {};
} // namespace Ui

QT_END_NAMESPACE

#endif // UI_PROJECTVIEW_H

You will get the errors you are seeing if that is not the case.

If it does have that (or if it does not!), start by deleting all files in your build output directory, re-run qmake, rebuild all from scratch. You may have some "stale" files around.

@JonB I don't know where the ui_*.h is located because it is now in the folder with project

In the build folder

[Dy3zz]

@jsulm

namespace Ui {
    class project: public Ui_project {};
} // namespace Ui

QT_END_NAMESPACE

#endif // UI_PROJECTVIEW_H

This is the end of the ui_viewproject.h file

@Dy3zz
You should follow the previously-suggested action:

EDIT
Actually, stop. You show

 class project: public Ui_project {};

That is not right, I said it should read projectView. Compare what you have against what I said should be there. I would suggest at some time you renamed the project/projectView class....

@Christian-Ehrlicher it works. Thanks both of you for your time

@Dy3zz
Both @Christian and @Ehrlicher ? ;-)
