openCV in Qt Creator on Mac

laxmi

I tried linking openCV to my Qt project by editing the project file which now reads:

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = image
TEMPLATE = app

DEFINES += QT_DEPRECATED_WARNINGS

CONFIG += c++11

SOURCES += \
        main.cpp \
        mainwindow.cpp

HEADERS += \
        mainwindow.h

FORMS += \
        mainwindow.ui

# Default rules for deployment.
qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += target

QT_CONFIG -= no-pkg-config
CONFIG  += link_pkgconfig
PKGCONFIG += opencv
INCLUDEPATH += \
    /usr/local/include
LIBS += `pkg-config --libs opencv`
PKG_CONFIG = /usr/local/bin/pkg-config

LIBS += \
    -L/usr/local/lib \
    -lopencv_core \
    -lopencv_highgui

But upon trying to run it I get the error:

:-1: error: opencv development package not found

I m using Mac version 10.14.5 , OpenCV version 2.4.13.

Hi and welcome to devnet,

You are mixing several things together. Just use the dedicated variable.

Next, where is the opencv.pc file located on your system ?
