I tried to create a simple Opencv application in Qt and upon running, the whole application is crashed. If I comment out the opencv related codes from the project, the project runs just fine.
What I did :
Downloaded the Qt 5.5.0 VS2013 64bit version
Downloaded the OpenCV 3.0
Downloaded the Cmake 3.3.2
There were already prebuilt binaries in when I extracted the Opencv package, But all tutorials on the net wanted me to recompile the source codes so did I.
the package contains :
build
sources
created a new folder named mymade to hold the binaries next to the other two directories.
so it now looks like this :
build
mymade
sources
Steps:
Fired up CMake, specified the source folder from the extracted files
and specified mymade as the output for binaries.
checked all options that had a opencv in their names, plus Qt! and configured it and subsequently generated the files.
This is the resulting contents :
So all is done and I now need to build the binaries. I opened OpenCV.sln and compiled the release and debug binaries .
the dlls are placed inside bin directory, and the lib files are placed inside lib folder .
Now its the time to configure the Qt projects .pro file So I used the header files from build directory, and for libs I used the lib folder from mymade folder. This is the first configuration that I came up with, which compiles without any linker issues, but crashes just immediately.
the initial changes in project file :
#-------------------------------------------------
#
# Project created by QtCreator 2015-10-06T14:04:20
#
#-------------------------------------------------
QT += core gui
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET = OpenCVTest
TEMPLATE = app
SOURCES += main.cpp\
mainwindow.cpp
HEADERS += mainwindow.h
INCLUDEPATH += L://Apps_Installation_Folder//opencv//build//include
LIBS += L://Apps_Installation_Folder//opencv//mymade//lib//Release//*.lib
FORMS += mainwindow.ui
doing this in project file as it was suggested by answers like this didnt do any good either :
#-------------------------------------------------
#

So what is the problem here? what am I missing ?
