Qt and OpenCV

Hi ! I know there are other threads about "Qt and OpenCV" but I didn't find any understable solution for my problem. Sorry if my search was not well done.

Here is my problem: I try to use someone else's code to create an UI (now it is just a console application). I never tried to run this code on my computer, I am not sure there is no problem but there wasn't problem on other computers, it was running well. The problem is that code uses some OpenCV functions, it uses:

#include <cv.h>
#include <highgui.h>

I tried to follow some advices and to search on this forum.

Until now, I wrote in my .pro file:

Code:

---

QT -= gui 
TARGET = testSeb 
CONFIG += console 
CONFIG -= app_bundle 
TEMPLATE = app 
SOURCES += main.cpp \ 
FichiersSources/SignatureImage.cpp \ 
FichiersSources/Repertoire.cpp \ 
FichiersSources/Librairie.cpp \ 
FichiersSources/FichierImage.cpp \

FichiersSources/BaseDImages.cpp

FichiersDEntete/Fichier.h \

"C:\OpenCV2.0\include\opencv" is the repertory where cv.h and highgui.h are.

But I obtained 17 errors and 45 warnings when compiling:

I did not paste all the message because it was too long. Please tell me how to post it if it is necessary.

I must say I don't understand at all... I am just a beginner, so it is quite difficult for me, sorry if my question is ridiculous...

Thank you in advance for your answers !

(I am sorry, I know my English is not good, but French is my mother tongue)

(Sorry, I do not find how to edit my thread).

In fact, my problem is solved ! I was using OpenCV 2.0 while the code was for version 1.0. Now everything is working well. There was no error in my project file, it was correct to do:

Code:

---

INCLUDEPATH += "D:\Program Files\OpenCV\cv\include" "D:\Program Files\OpenCV\cvaux\include" "D:\Program Files\OpenCV\cxcore\include" "D:\Program Files\OpenCV\otherlibs\highgui"
LIBS +=  -L"D:\Program Files\OpenCV\lib" -lcv -lcvaux -lhighgui -lcxcore
 
# Input
HEADERS += "D:\Program Files\OpenCV\cv\include\cv.h" "D:\Program Files\OpenCV\otherlibs\highgui\highgui.h"

This error is because you are using mingw gcc version less than 4.
you can check the version by going to qt command prompt and typing

g++ --version

if version less than 4 , install the latest gcc/g++ 4.x.x for mingw.

and also try changing line 68 in cxoperations.hpp from
#if __GNUC__ >= 4
to
#if __GNUC__ >= 4 || __MINGW32__
