MAC下 QT5.11.0+opencv的安装与配置

Dear 丶 2022-05-18 03:16 470阅读 0赞

首先——推荐个很好的网站~适合像我一样的初学者: [http://www.qter.org/][http_www.qter.org]  
下面我们一步步来~  
\#第一步:

*  到下面网址下载最新版的qt:  
    [http://download.qt.io/official\_releases/qt/][http_download.qt.io_official_releases_qt]
 *  或者也可在我的百度云链接里下载为5.11.0版本:  
    (qt-opensource-mac-x64-5.11.0):  
    [https://pan.baidu.com/s/1oQ9A0NdR3VWXZqzmoDh-CQ][https_pan.baidu.com_s_1oQ9A0NdR3VWXZqzmoDh-CQ]  
    \#第二步:
 *  可参照: [http://www.qter.org/portal.php?mod=view&aid=25][http_www.qter.org_portal.php_mod_view_aid_25]
 *  下载后,一步步安装即可

\#第三步:  
打开QT Creator

*  参照: [http://www.qter.org/portal.php?mod=view&aid=25&page=2][http_www.qter.org_portal.php_mod_view_aid_25_page_2]
 *  创建个helloworld窗口  
    \#第四步:  
    下面的就是具体的配置QT,那个网址没有具体的讲述…
 *  首先配置KIT:  
    重点看C++编译器和QT版本这两有的需要改  
    ![这里写图片描述][70]

\#第五步:配置opencv

*  用Homebrew下opencv, 具体我就不讲啦, 见网址:  
    mac上装Homebrew:  
    [https://blog.csdn.net/qq\_37486501/article/details/80632201][https_blog.csdn.net_qq_37486501_article_details_80632201]  
    然后在终端输入: brew install opencv即可.
 *  在新建的QT工程中的.pro文件中添加如下配置代码

INCLUDEPATH += /usr/local/include
    INCLUDEPATH += /usr/local/include/opencv
    INCLUDEPATH += /usr/local/include/opencv2
    LIBS += -L/usr/local/lib \
     -lopencv_core \
     -lopencv_highgui \
     -lopencv_imgproc \
      -lopencv_imgcodecs \

*  完成以上步骤后按理应该是能成功的，但是运行时发现会出现如下的错误。

dyld: Symbol not found: __cg_jpeg_resync_to_restart
    Referenced from: /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO
    Expected in: /usr/local/lib/libjpeg.8.dylib
    in /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO

*  我们来修改配置:  
    ![这里写图片描述][70 1]
 *  在main.cpp中, 粘贴如下代码:

#include"opencv2/core/core.hpp"
    #include"opencv2/highgui/highgui.hpp"
    //using namespace cv;
    int main(int argc, char *argv[])
    {
       cv::Mat image=cv::imread("/users/huang/desktop/meinv.jpg");
    
       cv::namedWindow("aaa");
    
       cv::imshow("myimage",image);
    
       cv::waitKey(50000);
    
        return 1;
    }

*  会发现出错了:  
    ![这里写图片描述][70 2]  
    原因是连接库失败  
    具体原因：  
    1.qmake.conf文件修改不正确  
    2.可能.pro文件中LIBS+=后面连接的库不对或不全，导致连接不正确，多添加几个库试试，看是否消除错误提示。（每次更改pro，重新配置编译，应先将工程目录下.pro.user文件和debug或release文件夹删除。）
 *  如何解决呢:

1.  进入Qt安装目录，打开5.4 /clang\_64 / mkspecs /macx-clang/qmake.conf , 将QMAKE\_MACOSX\_DEPLOYMENT\_TARGET = 10.7改为QMAKE\_MACOSX\_DEPLOYMENT\_TARGET = 10.10  
    等号后面10.7或10.10应为Xcode调用的系统framework版本号，我的是OS X Yosemite10.10，所以改成10.10。

\#\#我踩过了很多坑, 配置QT花了一天半的时间, 希望大家看过我的文章, 可以节省时间…借鉴过下面的很多文章:(下面的文章可行性很高, 如果配置后还是有错误, 可以到下面的文章中找答案.)
