QtcoSocket -QtNetwork Compile error

[Daxos]

Hi,
I have this kind of problem:

I have two class and both are subclass of qObject.
The first include onlly my personale include, the second class include QTcpServer and include Qt networnk (#include <QtNetwork>).

I want to be able to include the first class in the second class but I have this error:

: #error : qfile.h must be included before any header file that defines open

How i can solveed it?

Bye, Darui

Change the order of includes.

[Daxos]

If I change the order of include I have this error:

: error C2039: '_write' : is not a member of 'QTcpSocket'

[wysota]

Please show us your includes.

[Daxos]

Ok,
this is a piece of my first header:

A.h
 
#ifndef  A_H
#define A_H
 
#include <QTcpServer>
#include <QTcpSocket>
class B;
 
class A: public QObject
{
 ..  .. ..
};
#endif

A.h

#ifndef  A_H
#define A_H

#include <QTcpServer>
#include <QTcpSocket>
class B;

class A: public QObject
{
 ..  .. ..
};
#endif

To copy to clipboard, switch view to plain text mode 

and the implementation is:

A.cpp
#include "A.h"
#include <QtNetwork>
 
#include "B.h"
 
..
..
..

A.cpp
#include "A.h"
#include <QtNetwork>

#include "B.h"

..
..
..

To copy to clipboard, switch view to plain text mode 

Where B is:

B.h
#ifndef B
#define B
 
#include "HostInfo.h"
 
class B : public QObject
{
	Q_OBJECT

B.h
#ifndef B
#define B

#include "HostInfo.h"

class B : public QObject
{
	Q_OBJECT

To copy to clipboard, switch view to plain text mode 

the implementation is

#include "B.h"
 
..
..
..

#include "B.h"

..
..
..

To copy to clipboard, switch view to plain text mode 

while the class HostInfo is:

#ifndef HOSTINFO_H
#define HOSTINFO_H
 
#include "QTcpSocket"
 
typedef struct Host{
  QTcpSocket* pxSocket;
}HostInfo;
 
#endif

#ifndef HOSTINFO_H
#define HOSTINFO_H

#include "QTcpSocket"

typedef struct Host{
  QTcpSocket* pxSocket;
}HostInfo;

#endif

To copy to clipboard, switch view to plain text mode 

Thanks

Is it possible for you to prepare a minimal compilable example reproducing the problem?

Also: which exactly include line does the error refer to?

[Daxos]

I have solved my problem.

The problem is another propretary librabry that doesn't support Qt.
I have solved whit another design for my application.

Thanks and sorry if this is only my personal error.

Bye, Dax
