Question

Hi guys I am creating a simple game using cocos2d-x and blackberry. I need some place to store my game settings, something similar to shared preferences in ios and android. I found some code using qsettings, but the problem is I am not able to add the QtCore library.

I add the library using RightClick->configure->add Library and Standard BlackBerry Platform Library. The library gets added successfully.

#include "dataProcessor.h"
#include <QtCore>

void dataProcessor::setup(){
    QDir dir;
    dir.mkpath("data/files/text");
    dir.cd("data/files/text");
}

but when I compile the above code, I get the error C:/Users/I076636/Documents/target_10_0_9_1673/qnx6/usr/include/qt4/QtCore/qatomic.h:45:28: fatal error: QtCore/qglobal.h: No such file or directory

But I noticed 2 things,
1.qglobal.h file is there inside the QtCore directory I have included.
2.inside qatomic.h if I change

#ifndef QATOMIC_H
#define QATOMIC_H

#include <QtCore/qglobal.h>
#include <QtCore/qbasicatomic.h>

into

#ifndef QATOMIC_H
#define QATOMIC_H

#include <qglobal.h>
#include <QtCore/qbasicatomic.h>

the error for qglobal goes and now the same error comes for qbasicatomic.h.

I think it is something simple like incorrect mapping between QtCore keyword and include directory or something..

Please do have a look.

The IDE is made on eclipse.

You can understand what is going wrong if you look closely at the error message:

/target_10_0_9_1673/qnx6/usr/include/qt4/QtCore/qatomic.h:45:28:
fatal error: QtCore/qglobal.h: No such file or directory

The error isn’t in your inclusion of QtCore, but is occurring inside QtCore/qatomic.h, on line 45 (you can find this file in the [YOUR BBNDK DIRECTORY]/target_10_0_9_1673/qnx6/usr/include/qt4/QtCore/qatomic.h):

#include <QtCore/qglobal.h>

qatomic.h is already in the QtCore directory, and you’ll find a qglobal.h directory there as well. So what this means is that qatomic.h expects the parent directory to be on the include path, so that including <QtCore/qglobal.h> will work.

So you just need to add [YOUR BBNDK DIRECTORY]/target_10_0_9_1673/qnx6/usr/include/qt4 to your include directories.

Do it like this:

1. Right click over your project in Project Explorer and choose Properties
2. Expand the tree to C/C++ General / Paths and Symbols
3. Change the Configuration in the Paths and Symbols frame to [All configurations]
4. Click the Includes tag and select GNU C in the Languages list (or do this for every language).
5. Click Add... and type ${QNX_TARGET}/usr/include/qt4 and press OK
6. Click Add... and type ${QNX_TARGET}/usr/include/qt4/QtCore and press OK

Now your include of #include <QtCore> should work.
