POUndefined Opencv References when using Qt + Opencv
text
Body
copied!<p>Hello im basically trying to make an application that shows and Opencv Iplimage converted to QImage in a label, i did a simple example and it worked just fine, but now when i try to integrate that image convertion to another project,i get undefined Opencv functions references like this: undefined reference to `cvQueryFrame'all from the Highgui </p> <p>Im actually using the same library paths i used when i first tried that image convertion, just that this time its not working. Im quite new with Qt, and i dont know where the problem might be:</p> <pre><code> #include <qt4/QtGui/QApplication> #include "myqtapp.h" #include <iostream> #include <stdlib.h> #include <stdio.h> #include <opencv/highgui.h> #include <opencv/cv.h> using namespace std; int main(int argc, char *argv[]) { QApplication app(argc, argv); myQtApp *dialog = new myQtApp; //******************************************************************************************************** QImage myImage; QLabel label_5; IplImage* frame; //label_5 = new QLabel(myQtAppDLG); //Not using this Yet CvCapture* capture = cvCreateFileCapture( "garden.bmp" ); frame = cvQueryFrame( capture ); cvCvtColor(frame,frame,CV_BGR2RGB); myImage = QImage((unsigned char *)frame->imageDataOrigin,frame->width,frame->height,QImage::Format_RGB888); //label_5.setPixmap(QPixmap::fromImage(myImage)); //Not using this Yet //******************************************************************************************************** dialog->show(); return app.exec(); </code></pre> <p>}</p> <pre><code> main.cpp:(.text+0x44): undefined reference to `cvCreateFileCapture' main.cpp:(.text+0x4c): undefined reference to `cvQueryFrame' main.cpp:(.text+0x62): undefined reference to `cvCvtColor' </code></pre> <p>As you see the first thing i try to do is just to use some Opencv Functions like CvQueryFrame, the funny thing is that im using the exact same include paths i used the first time, also linked the exact same dynamic libraries. I've tried different paths and compiler but nothing seems to work, i dont know where the error might be. Im using Linux Ubuntu and Netbeans C++, Any hint?</p>
