OpenCL access violation with x64/MSVC2015 [closed]

asked 2017-03-09 04:56:55 -0500

I'm a new user of openCV. Having built the .dlls on MSVC2015, targeting x64, I get the following error when trying to run a test program QuickView.exe.

#include <opencv2/core.hpp>
#include <opencv2/imgcodecs.hpp>
#include <opencv2/highgui.hpp>
#include <iostream>

using namespace cv;
using namespace std;

int main(int argc, char** argv)
    if (argc != 2)
        cout << " Usage: display_image ImageToLoadAndDisplay" << endl;
        return -1;
Mat image;
image = imread(argv[1], IMREAD_COLOR); // Read the file

if (image.empty()) // Check for invalid input
    cout << "Could not open or find the image" << std::endl;
    return -1;

namedWindow("Display window", WINDOW_AUTOSIZE); // Create a window for display.
imshow("Display window", image); // Show our image inside it.

waitKey(0); // Wait for a keystroke in the window
return 0;


The error I get is exception thrown at 0x000007FEDD58A32A (igdrcl64.dll) in QuickView.exe: 0xC0000005: Access violation reading location 0x0000000000000990.

I can apparently continue past the error with no ill effects.

The call stack is (with apologies for the line length)

Obviously imshow is calling something deep within OpenCL that is giving a problem. The workarounds I have successfully tested are to compile OpenCV without OpenCL support (comment out line 124 in cvconfig.h), or to switch off Win32 Access Violation catching. However, neither of these seem very satisfactory. Can anyone suggest a proper remedy, please?

first don't change cvconfig.h. if you want to disable opencl use


What is your graphic card?

Intel(R) HD Graphics 530 (on a Dell Precision 7510 laptop). Dell may have used a custom variant for them.

I think something is wrong in your configuration. Clean your solution in VS 2015 (all opencl kernels will be deleted) and rebuild opencv with opencl. Please don't change source code because it is difficult to help you. try to reproduce error using ocl::setUseOpenCL(false);

Updating the graphics driver has cured the problem. Thanks to LBerger for pointing me in the right direction.
