Qtcreator under Wine ( MinGw compilant ) error report

heatblazer

Hello, I am trying to test OpenCV with QtCreator, I`ve followed some examples, that supposedly should work, but the console shows me a strange error.
Here is the pro. file:
@TEMPLATE = app
QT += core
QT -= gui
CONFIG += console
CONFIG -= app_bundle

TEMPLATE = app
win32 {

message("*using settings for windows")
INCLUDEPATH += "Z:\\home\\ilian\\OpenCV_WINE\\opencv\\build\\include" \
                "Z:\\home\\ilian\\OpenCV_WINE\\opencv\\build\\include\\opencv" \
                "Z:\\home\\ilian\\OpenCV_WINE\\opencv\\build\\include\\opencv2"

LIBS += -L "Z:\\home\\ilian\\OpenCV_WINE\\opencv\\build\\x86\\mingw\\lib" \
        -lopencv_core243 \
        -lopencv_highgui243 \
        -lopencv_imgproc243

}

SOURCES += main.cpp

@

and the main.c fie:
@#include "opencv2/highgui/highgui.hpp"
#include <QString>
#include <QCoreApplication>
#include <QDebug>

using namespace cv;

int main(int argc, char** argv)
{

QCoreApplication app(argc, argv);
QString vlad ("Z:\\home\\ilian\\vladi.jpg");
Mat im = imread(vlad.toStdString(), 1);
qDebug() << vlad;
if ( im.empty() ) {
    return -1;
}
imshow("image", im);
waitKey(0);

return app.exec();

}
@

The error shown by running (release or debug) is:
@terminate called after throwing an instance of 'std::length_error'
what(): basic_string::assign@

Hi,

Using Wine adds extra complexity.

What happens if you develop directly in Windows? Or if you download the Linux libraries?

I don`t have windows right now, and for linux I have no problems, I need the windows testings and builds because I am making a camera software under opencv.
