Qt - Unexpected GDB Exit - c++

Question

I am trying to develop an application that creates an image and fills it with color pixels using bilinear interpolation and then displays it. My code so far is the following:
#include <QtCore/QCoreApplication>
#include <opencv/cv.h>
#include <opencv/highgui.h>
#include <iostream>
#include <string>
#include <sys/stat.h>
using namespace cv;
int main()
{
Mat image;
image.create( 500, 500, CV_8UC3);
//upper left corner
Vec3b ul( 255, 0, 0 );
//upper right corner
Vec3b ur( 0, 255, 0 );
//bottom left corner
Vec3b bl( 0, 0, 255 );
//bottom right corner
Vec3b br( 255, 0, 255 );
//for(int y=0;y<image.rows; y++)
//for(int x=0;x<image.cols;x++)
// call function to add noise
namedWindow("Colored Pixels");
imshow("Colored Pixels", image);
// shows image for 5 seconds
waitKey(10000);
return 0;
}
When I run my program in debug mode I get the following two pop up windows:
Unexpected GDB Exit
The gdb process exited unexpectedly (code 0)
and
Executable Failed
During startup program exited with code 0xc0000138
my debugger log screen shows the following:

do you have any idea as to how I can handle this?

Answer 1

Exit code 0xc0000138 is STATUS_ORDINAL_NOT_FOUND (I checked it by perl -MWin32::Status -E 'say $Win32::Status::INTEGER_TO_SYMBOL{ 0xc0000138 }', it can also be found in the ntstatus.h header, e.g. http://source.winehq.org/source/include/ntstatus.h)
An "ordinal not found" error means that some function provided by a DLL couldn't be found; possibly the wrong version of the DLL was loaded. I'm not sure if the same error can be produced when a DLL is entirely missing.
Can you verify the following?
OpenCV DLL(s) exist
OpenCV DLL(s) are in PATH
OpenCV DLL(s) match the version of your <opencv/*> headers
OpenCV libs are listed in your .pro file; there should be some LIBS+=... statements relating to OpenCV. There's an example of what it might look like here - http://mobidevelopers.wordpress.com/2009/01/29/qt-and-opencv/

Answer 2

Never mind I just reinstalled everything. It seems some files were colliding with another installation I'd done in the past ;)
