使用qmake在Ubuntu中一起编译QT和OpenCV
[英]compile QT and OpenCV together in Ubuntu using qmake
问题描述
Im writing a OpenCV application and a QT GUI together and im having some issues compiling. 
我正在一起编写OpenCV应用程序和QT GUI，并且在编译时遇到了问题。 Some background information that might be useful; 一些可能有用的背景信息； the OS is Ubuntu 13.10, the output of " qmake --version" is :QMake version 3.0 Using Qt version 5.0.2 in /usr/lib/x86_64-linux-gnu 操作系统是Ubuntu 13.10，“ qmake --version”的输出是：QMake版本3.0在/ usr / lib / x86_64-linux-gnu中使用Qt版本5.0.2
The issues starts upon the appearance of one line of code, that being "Mat cvImage" where I declare a Mat object. 问题始于一行代码的出现，即我声明一个Mat对象的“ Mat cvImage”。 The way im compiling is first "qmake -project" then "qmake" then i go into my .pro file and add "QT += widgets" and then I type "make", when i do this, i get the error im编译的方式是先“ qmake -project”，然后是“ qmake”，然后我进入我的.pro文件并添加“ QT + =小部件”，然后键入“ make”，当我这样做时，出现错误
/usr/lib/x86_64-linux-gnu/qt5/bin/qmake -o Makefile gui2.pro
g++ -c -m64 -pipe -O2 -Wall -W -D_REENTRANT -fPIE -DQT_NO_DEBUG -DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_CORE_LIB -I/usr/share/qt5/mkspecs/linux-g++-64 -I. -I. -I/usr/include/qt5 - I/usr/include/qt5/QtWidgets -I/usr/include/qt5/QtGui -I/usr/include/qt5/QtCore -I. -o main.o main.cpp
main.cpp: In function ‘int main(int, char**)’:

Mat cvImage;

class CV_EXPORTS Mat
^
main.cpp:55:6: error: expected ‘;’ before ‘cvImage’
Mat cvImage;
^
make: *** [main.o] Error 1
To be honest, i have no idea what "In file included from main.cpp:20:0: /usr/local/include/opencv2/core/core.hpp:1683:10 note: 'cv :: Mat' " means. 老实说，我不知道“在main.cpp：20：0中包含的文件中：/usr/local/include/opencv2/core/core.hpp:1683:10注意：'cv :: Mat'”的意思是。 I included all the appropriate OpenCV libraries and I dont know how to interpret that line of error output. 我包括了所有适当的OpenCV库，但我不知道如何解释这一行错误输出。 Below is my code 下面是我的代码
/*****************C++ Libraries******************/
#include <iostream>
/****************User Defined*******************/
#include "function.h"
#include "function.cpp"
/****************Libraries Needed for QT********/
#include <QObject>
#include <QApplication>
#include <QWidget>
#include <QGridLayout>
#include <QSpinBox>
#include <QLabel>
#include <QGraphicsScene>
#include<QGraphicsView>
#include <QGraphicsPixmapItem>
/************Libraries Needed For OpenCV*******/
#include <opencv2/core/core.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/highgui/highgui.hpp>
using namespace std;
int main(int argc, char ** argv){
QApplication a(argc, argv);
/** some code that runs a gui ***/
Mat cvImage; // This is where the problem starts
window.show();
return a.exec();
}
I also looked into my Makefile and i dont see any paths or anything to OpenCV libraries so I tried adding them, it caused more problems. 我也查看了我的Makefile，但看不到OpenCV库的任何路径或任何内容，因此尝试添加它们，这引起了更多问题。
This is the auto-generated Makefile(via the qmake command) 这是自动生成的Makefile（通过qmake命令）

As clang is trying to tell you, you forgot the openCV namespace. 正如clang试图告诉您的那样，您忘记了openCV命名空间。
use either: 使用：
cv::Mat cvImage;
or 要么
using namespace cv;
See the documentation . 请参阅文档 。

I found out that all I had to do was include the libraries that i needed into "LIBS" in the Makefile. 我发现我所要做的就是将需要的库包含到Makefile的“ LIBS”中。 So this is the solution,at the end of LIBS in the Makefile or at the bottom add the line 所以这是解决方案，在Makefile的LIBS末尾或底部添加以下行
`LIBS += pkg-config --libs opencv`
this line can actually be added anywhere in the "Compiler, tools and options" section of the Makefile(refer to the Makefile code posted in the original question). 实际上，可以在Makefile的“编译器，工具和选项”部分的任何位置添加此行（请参阅原始问题中发布的Makefile代码）。
Additionally, my lack of "namespace" was also an issue! 另外，我缺少“命名空间”也是一个问题！
