Qt problem to include opencv library

Bekhouche

Hello,

I have Qt 5.2.1 Windows & vs11 compiler (x86), this is my .pro file :
@
SOURCES = facerecognitiondemo.cpp main.cpp
HEADERS = facerecognitiondemo.h
FORMS = facerecognitiondemo.ui

target.path = $$[QT_INSTALL_EXAMPLES]/uitools/FaceRecognitionDemo
INSTALLS += target

QT += widgets

OPENCV_PATH = E:\opencv

LIBS_PATH = "$$OPENCV_PATH/build/x86/vc11/lib"

CONFIG(debug, debug|release) {
LIBS     += -L$$LIBS_PATH \
            -lopencv_core246d \
            -lopencv_highgui246d \
            -lopencv_objdetect246d
}

CONFIG(release, debug|release) {
LIBS     += -L$$LIBS_PATH \
            -lopencv_core246 \
            -lopencv_highgui246 \
            -lopencv_objdetect246
}

When i build i get this error :
E:\Qt\qt5.2.1\Tools\qtcreator\bin\facerecognitiondemo\frdb.h:9: error: C1083: Cannot open include file: 'opencv/cxcore.h': No such file or directory

you should add

@INCLUDEPATH += $$OPENCV_PATH/src/include@

maybe src is not needed, take a look in the directory where to find:

"opencv/cxcore.h"

[quote author="hpollak" date="1395215900"]you should add

@INCLUDEPATH += $$OPENCV_PATH/src/include@

"opencv/cxcore.h"

[/quote]
it's not working this is the full path
@E:\opencv\build\include\opencv@

Qt 5.2.1
this is the full project
https://www.dropbox.com/s/hmbl3e8hj7ygq4a/FaceRecognitionDemo.rar
and this is the opencv directories (opencv 2.4.8 windows):
E:\opencv\build
E:\opencv\sources

andreyc

In you project file you put
@
INCLUDEPATH += E:\opencv\build\include
@

And in you sources you use
@
#include <cxcore.h>
@

You should change either INCLUDEPATH
@
INCLUDEPATH += E:\opencv\build\include\opencv
@

or #include directive
@
#include <opencv/cxcore.h>
