本人用qt creator 创建了一个gui application
MyTest.h
- C/C++ code
#ifndef MYTEST_H#define MYTEST_H#include <QtGui/QWidget>#include <cv.h>#include <QImage>#include <QtCore>#include <highgui.h>class MyTest : public QWidget{ Q_OBJECTpublic: MyTest(QWidget *parent = 0); ~MyTest(); void showImage(char *filename); QImage& pConvQImage(IplImage *p,QImage &q);private: IplImage * pImage; QImage qImage;};#endif // MYTEST_HMyTest.cpp
- C/C++ code
#include "mytest.h"#include <QPainter>MyTest::MyTest(QWidget *parent) : QWidget(parent){ this->showImage("lena.jpg");}MyTest::~MyTest(){}void MyTest::showImage(char *filename){ pImage = cvLoadImage(filename,1); QPainter q; q.drawImage(this->rect(),pConvQImage(pImage,qImage));}QImage& MyTest::pConvQImage(IplImage *p, QImage &q){ q = QImage((const uchar*)p->imageData,p->width,p->height,p->widthStep,QImage::Format_RGB888); return q;}main.cpp
- C/C++ code
#include <QtGui/QApplication>#include "mytest.h"int main(int argc, char *argv[]){ QApplication a(argc, argv); MyTest w; w.show(); return a.exec();}test_OpenCV4.pro
- C/C++ code
TARGET = test_OpenCV4TEMPLATE = appSOURCES += main.cpp\ mytest.cppHEADERS += mytest.hINCLUDEPATH += D:\OpenCV2.0\include\opencv \ LIBS \ += \ D:\OpenCV2.0\lib
运行的时候就出现一个错误，但是找不到错误在哪里，请高手指点一二
- Assembly code
D:/learning/workspace/test_OpenCV4/mytest.cpp:17: undefined reference to `cvLoadImage':-1: error: collect2: ld returned 1 exit status
------解决方案--------------------
pImage = cvLoadImage(filename,1);
没找到这个函数在那声明定义的，你自己再找找吧
