Eclipse error - method setupUi could not be resolved

[libed]

Hi
I'm working on Eclipse IDE with qt4 plugin. Everythings work fine, all programs are compiling well, with no errors from compilator.
But I have one very annoying error which comes from Eclipse IDE.
syntax checker underlines ui.setupUi(this); with message: Method setupUi could not be resolved. This error have no matter for my application, and its work fine. but i cant stand to see the red underline in my project. I think that the problem is with my eclipse configuration.

here is the class with that error:

#include "qtmyapp.h"
 
QTMyApp::QTMyApp(QWidget *parent)
    : QWidget(parent)
{
	ui.setupUi(this); // <-- here is the error
}
 
QTMyApp::~QTMyApp()
{
 
}
 
#include <QtGui/QWidget>
#include "ui_qtmyapp.h"
 
class QTMyApp : public QWidget
{
    Q_OBJECT
 
public:
    QTMyApp(QWidget *parent = 0);
    ~QTMyApp();
 
private:
    Ui::QTMyAppClass ui;   //<-- and here
};

#include "qtmyapp.h"

QTMyApp::QTMyApp(QWidget *parent)
    : QWidget(parent)
{
	ui.setupUi(this); // <-- here is the error
}

QTMyApp::~QTMyApp()
{

}

#include <QtGui/QWidget>
#include "ui_qtmyapp.h"

class QTMyApp : public QWidget
{
    Q_OBJECT

public:
    QTMyApp(QWidget *parent = 0);
    ~QTMyApp();

private:
    Ui::QTMyAppClass ui;   //<-- and here
};

Try adding the directory where ui_*.h files are placed to eclipse indexer search paths.

Hi
thank you for reply, but I dont know what path are you mean.
project include path?

[stampede]

No, I mean in eclipse project settings. I don't have access to eclipse at the moment, so I can't tell you how to do that step-by-step. But try to search for something like "source paths", "include paths" or sth like that in project settings.

Hi,

I had exactly the same error. I found this solution:

1 - Go to your project's properties [alt+enter];
2 - Go to left menu option C/C++ general->Indexer;
3 - Check all check boxes (just like the picture).

That's it.

Good luck.

If rafaelccomp's suggestion didn't fix it then this probably will:

Check if you can find the ui_qtmyapp.h file in your project folder.

If you can't then run the following command while in your project folder:

<your_QT_Path>\bin\uic.exe qtmyapp.ui -o ui_qtmyapp.h

you'll see a new file, refresh your eclipse project and enjoy

(you still need what rafaelccomp suggested in addition to the above)

Edit: Actually the real problem is that Eclipse can't find "make.exe" to build the project...and hence unable to execute that command in the makefile.

As suggested by someone on another qt forum in 2008 > go to your mingw\bin folder and make a copy of mingw32-make.exe and rename that copy to make.exe

build the project and you'll be fine!

I know this thread is a little old, but to add to this, you can also change the C/C++ Make Project make Build Command to mingw32-make
