Question

скомпилировать QT и OpenCV вместе в Ubuntu, используя qmake

0

Я пишу приложение OpenCV и графический интерфейс QT вместе, и имейте некоторые проблемы компиляции. Некоторая справочная информация, которая может быть полезна; ОС - Ubuntu 13.10, вывод "qmake --version": QMake версии 3.0 Использование Qt версии 5.0.2 в /usr/lib/x86_64-linux-gnu

Проблемы возникают при появлении одной строки кода, которая является "Mat cvImage", где я объявляю объект Mat. Способ im компиляции - это сначала "qmake -project", затем "qmake", затем зайдите в мой.pro файл и добавьте "QT + = widgets", а затем введите "make", когда я это сделаю, я получаю ошибку

/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**):
main.cpp:55:2: error: ‘Mat was not declared in this scope
  Mat cvImage;
  ^
main.cpp:55:2: note: suggested alternative:   
In file included from main.cpp:20:0:
/usr/local/include/opencv2/core/core.hpp:1683:18: note:   ‘cv::Mat
 class CV_EXPORTS Mat
                  ^
main.cpp:55:6: error: expected ‘; before ‘cvImage
  Mat cvImage;
  ^
make: *** [main.o] Error 1

Честно говоря, я понятия не имею, что такое "В файле, включенном в main.cpp: 20: 0: /usr/local/include/opencv2/core/core.hpp:1683:10 note:" cv :: Mat "означает, Я включил все соответствующие библиотеки OpenCV, и я не знаю, как интерпретировать эту строку ошибки. Ниже мой код

/*****************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();
}

Я также заглянул в мой Makefile, и я не вижу никаких путей или чего-либо в библиотеках OpenCV, поэтому я попытался добавить их, что вызвало больше проблем.

Это автоматически сгенерированный Makefile (через команду qmake)

как насчет пространства имен opencv? cv::Mat или использование namespace cv ;

@itwasntpete, это хороший момент, но когда я это делаю, я получаю следующую ошибку ... main.cpp :(. text._ZN2cv3MatD2Ev [_ZN2cv3MatD5Ev] + 0x69): неопределенная ссылка на cv::Mat::deallocate()' main.cpp:(.text._ZN2cv3MatD2Ev[_ZN2cv3MatD5Ev]+0x54): undefined reference to cv :: fastFree (void *)' collect2: error: ld вернул 1 состояние выхода make: *** [gui2] Ошибка 1

это ошибка компоновщика. Вы должны связать свою компиляцию с библиотекой. увидеть этот или этот пост.

я думаю, что моя проблема связана с линковкой ... но, видите, я использую QT, поэтому именно qmake генерирует Makefile. Я знаю, как заставить файлы OpenCV компилироваться и связываться без проблем, проблема в том, что я использую и QT, и OpenCV, и QT автоматически генерирует Makefile, и я не знаю, что я должен с этим делать. Я попытался включить "LDFLAGS + = pkg-config --libs opencv " в CFLAGS, и я попытался включить эту строку "LDFLAGS + = pkg-config --libs opencv ", но безуспешно

в файле вашего проекта из qt вы можете вставить флаги, которые будут иметь место в сгенерированном make-файле. вот список вариантов. вам нужно вставить что-то вроде LIBS += -L/path/to/lib -lname_of_lib как вы это сделали бы в make- LIBS += -L/path/to/lib -lname_of_lib .

Как клан пытается рассказать вам, вы забыли пространство имен openCV.

используйте либо:

cv::Mat cvImage;

или

using namespace cv;

См. Документацию.

Я узнал, что все, что мне нужно было сделать, это включить библиотеки, которые мне нужны, в "LIBS" в Makefile. Итак, это решение, в конце LIBS в Makefile или внизу добавить строку

'LIBS += pkg-config --libs opencv'

эту строку можно фактически добавить в разделе "Компилятор, инструменты и параметры" в файле Makefile (см. код Makefile, опубликованный в исходном вопросе).

Кроме того, моя нехватка "пространства имен" также была проблемой!
