在Blackberry 10 SDK中添加QtCore库 [英] Adding QtCore Library in blackberry 10 sdk

问题描述

大家好，我正在使用cocos2d-x和blackberry创建一个简单的游戏.我需要一些地方来存储我的游戏设置，类似于ios和android中的共享首选项.我使用qsettings找到了一些代码，但是问题是我无法添加QtCore库.

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.

我使用RightClick-> configure-> add Library和Standard BlackBerry Platform Library添加该库.该库已成功添加.

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");
}

但是当我编译上面的代码时，出现错误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 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

但是我注意到两件事， 我包含的QtCore目录中有1.qglobal.h文件. 2.在qatomic.h内部(如果我更改

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>

进入

#ifndef QATOMIC_H
#define QATOMIC_H

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

qglobal的错误消失了，现在qbasicatomic.h也出现了同样的错误.

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

我认为这很简单，例如QtCore关键字与包含目录之类的映射不正确.

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

请看看.

IDE是在Eclipse上制作的.

推荐答案

如果仔细查看错误消息，您可以了解出了什么问题:

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

错误不包含在QtCore中，而是发生在QtCore/qatomic.h内部，在第45行(您可以在[YOUR BBNDK DIRECTORY]/target_10_0_9_1673/qnx6/usr/include/qt4/QtCore/qatomic.h中找到此文件):

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已经在QtCore目录中，并且您还将在其中找到qglobal.h目录.因此，这意味着qatomic.h希望父目录位于包含路径上，以便包含<QtCore/qglobal.h>都可以使用.

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.

因此，您只需要将[YOUR BBNDK DIRECTORY]/target_10_0_9_1673/qnx6/usr/include/qt4添加到您的包含目录中即可.

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

这样做:

1. 在Project Explorer中右键单击您的项目，然后选择Properties
2. 将树扩展到C/C++ General/Paths and Symbols
3. 将路径和符号"框中的配置更改为[All configurations]
4. 单击Includes标记，然后在语言"列表中选择GNU C(或对每种语言都执行此操作).
5. 单击Add...并键入${QNX_TARGET}/usr/include/qt4并按OK
6. 单击Add...并键入${QNX_TARGET}/usr/include/qt4/QtCore并按OK

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

现在您包含#include< QtCore>了.应该可以.

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