error compile

Hi, I have this error; my command is: nmake clean; qmake; nmake (the last get this error)
NMAKE : fatal error U1071: cycle in dependency tree for target 'ui\mainform.h'
Stop.
What happen?

Could we see the project file?

Code:

---

SOURCES	+= main.cpp \
	widget.cpp \
	plainit.cpp 
 
HEADERS	+= widget.h \
	plainit.h 
 
DISTFILES += program.txt
message( "version  0.5" )
DESTDIR = .
 
 
unix {
  UI_DIR = .ui
  MOC_DIR = .moc
  OBJECTS_DIR = .obj
}
win32 {
  UI_DIR = ui
  MOC_DIR = moc
  OBJECTS_DIR = obj
  thread {
       DEFINES += QT_THREAD_SUPPORT
  }
}
 
 
# Input

Delete your old Makefile and then qmake to generate a new one.

Everytime I do: nmake clean; qmake; nmake. But problem persist..

"clean" does not remove the Makefile.

Could you post your mainwindow.ui file? As attachment please :)

I have delete makefile; it's the same
yes here mainform.ui file...thanks

You are including the .ui file into that same .ui file? Why so?

I don't to do this; from designer (in implementation) there isn't mainform.ui.h; in mainform.h the same....I see now that I have 2 <optiondiaog.h> in mainform. h.
What is happen? How change it? I edit mainform.ui.h and delete the line?
thanks

HI, I tried to delete the line in mainform.ui.h (now there isn't). But problem don't change...
I think the problem is inside myToolbox: I have enable/disable it form qtDesigner but I see that some object inside it (label, spinbox...) aren't going enable! And from qt designer I can't enable object inside myToolbox. How can do?

If you open that .ui file in a text editor, you'll see (near the end of the file) a line telling that you do.

yes see. But designer has add this line. I have an older version of mainform.ui that has the same line

Code:

---

<include location="local" impldecl="in implementation">mainform.ui.h</include>

---

but this compile successfully....
I don't understand....

Ah... ok, I missed that ".h" at the end of the entry. Where do you include mainwindow.h? Could you find all occurences?

I have an old version of my mainform.ui and substituting it, compile! the problem seems inside this file....but this copy is very older.....

Sorry but I am still stop.....Any other suggests?

Hi,
I change including <mywidget.h> from declaration to implementation (in qtDesigner) and now compile. But Why?
Thanks

And what is mywidget.h? Could we see its contents? Are you by any chance including mainwindow.h there?

Code:

---

ifndef MYWIDGET_H
#define MYWIDGET_H
#include <qgl.h>
#include <qpoint.h>
#include <qtimer.h>
#include "mainform.h"
class MainForm;
#define BUFSIZE 512
 
class MyWidget : public  QGLWidget 
    {		 
        Q_OBJECT
    public:
 
         MyWidget( QWidget *parent = 0, const char *name = 0, const QGLWidget* shareWidget = 0);
        ~MyWidget();
.........
};

Is it #include "mainform.h" the problems? I need take it here... But wich is different between include in implem and in declaration? I thought it was the same for success of compile...

Probably yes.

No you don't. Do you use methods defined there?

No. You should avoid including to much files in headers, because it slows down the compilation. But the reason of failure might be that qmake sees that it needs that included file in the current file, but that file is included in the other one, so it depends on it and thus it creates a cycle. Of course it might be something different, but you should try removing that include from the header file.

yes I use members of mainform from here; But if I put it in implementation compile..

including much headers where? from QTdesigner? in implementation? in declarations? Or at begin of file by hand?

thanks

In header files. Because each file which includes that file will also include all the files including it and each time cpp has to parse them. That's why using precompiled headers results in such a big speed gain ;) Parsing header files takes much time.

Sorry but I have some problems with english also. Do you say me to put #incldue much more In implementation or implemention (from qtDesinger).
And is this an help for speed:

Code:

---

#ifndef MYWIDGET_H
#define MYWIDGET_H
.......

Thanks
