| commented question | opencv_highgui320: Qt5 .dlls required and 0xc000a200 error Laurent - QT5 is required for highgui. How do you use opencv3 without it? Even when I compiled cmake with_Qt:OFF it still required it. i am in debug for Qt, opencv, and my application |

| commented question | opencv_highgui320: Qt5 .dlls required and 0xc000a200 error Any thoughts Laurent? It works every few times I build but usually sends out that same 0xc000a200 error I cannot figure out why. |

| commented question | opencv_highgui320: Qt5 .dlls required and 0xc000a200 error No - Qt5.8 does not seem to include a .dll called Qt5.dll. I do have Qt5Cored.dll, Qt5Networkd.dll, Qt5Guid.dll, Qt5Multimedia.dll, and Qt5Testd.dll,and Qt5Widgetsd.dll.I copied and pasted all the Qt5*.dlls in to test that. It worked briefly but stopped on the next time I built the solution. |

| asked a question | opencv_highgui320: Qt5 .dlls required and 0xc000a200 error I tried building opencv With_Qt:off and on. Either way including opencv_highgui in my project compiles but won't allow my project .exe to unless (1) it can find the Qt5 .dlls and (2)even then it throws a 0xc000a200 error, which I have found it linked to app container. I have tried building opencv with cmake_exe_linker_flags, cmake_module_linker_flags, and cmake_shared_linker_flags with the /APPCONTAINER:NO flag but this has not solved it. Any other suggestions? I am building opencv3.2.0 in windows 10, VS2015, and using cmake-gui for x86. Thanks!

2017-03-16 10:48:43 -0600
| asked a question | cv::flip keeps throwing bad ptr exceptions No matter which flip code I call with cv::flip, I keep getting bad ptr exceptions. For flipcode <1, it errors out at flipVert (copy.cpp, l.418) on src1. const uchar* src1 is defined at l.405 with a simple equation, not sure why that should be an issue. For flipcode==1, the error is in flipHoriz (copy.cpp, l.395). I am calling cv::flip(imgcv,imgcv2,flipcode) after I convert a QImage into a Mat using: Mat imgcv = QImage2Mat(img);
Mat imgcv2;
cv::flip(imgcv,imgcv2,flipcode);
/*static*/ Mat DisplayVideoQt::QImage2Mat(QImage const& src)
{
QImage temp = src.copy();
Mat res(temp.height(),temp.width(),CV_8UC3,(uchar*)temp.bits(),temp.bytesPerLine());
cvtColor(res,res, CV_BGR2RGB);
return res;
}

| commented question | image.data won't load also, how do I get my includes and namespaces into the copy-pasted code box - they get formatted funny? |
|
2017-03-10 13:55:58 -0600
| asked a question | image.data won't load I'm sure this has been asked before but my basic sample 'load image' code keeps failing. #include "opencv2\core\core.hpp"
#include "opencv2\highgui\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],CV_LOAD_IMAGE_COLOR); // Read the file
if(! image.data ) // Check for invalid input
{
cout << "Could not open or find the image" << std::endl ;
cout << image.size();
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;
}
This code always errors at at the second test (! image.data). The image.size() returned is [0x0].
I have tried both .jpg and .bmp images that are definitely in the path (same dir as the .exe) I googled around and cannot find anything. My code compiles fine. I am working in VS2008 (Win32) for various necessary reasons. |

| commented question | Building OpenCV 3.2.0 with VS2015 as x86 You're right - Im building OpenCV 3.2.0 - not 2.4.8 but that just was me being confused - I will revise the question - even the simplest code (below) fails #include <iostream>
#include <opencv2\core\core.hpp>
using namespace cv;
using namespace std;
int main(int argc, char** argv)

| commented question | Building OpenCV 3.2.0 with VS2015 as x86 The code I was given (displayvideoqt) uses qt but it's not essential for what I want to do with opencv.
I am compiling the code for OpenCV 2.4.8 from the source. As part of this of course I build opencv_core320d.lib which I then put into my property>linker sheet |

2017-03-03 13:55:05 -0600
| asked a question | Building OpenCV 3.2.0 with VS2015 as x86 I have code written many years ago (displayvideoqt) for Win32 that I want to add opencv functions to. I did all the include, linker, and library options in VS2015, compiled from scratch using CMake, etc and no matter what I try to tweak I always get the following error just from trying to use cv::Mat (#include <opencv2\core\core.hpp> displayvideoqt.obj : error LNK2019: unresolved external symbol "int __cdecl cv::_interlockedExchangeAdd(int *,int)" (?_interlockedExchangeAdd@cv@@YAHPAHH@Z) referenced in function "public: void __thiscall cv::Mat::release(void)" (?release@Mat@cv@@QAEXXZ) I have found that in cv::Mat::release() CVX_ADD is defined as this cv::_interlockedExchangeAdd(int *, int) in core/system.hpp. It appears that the function is actually defined in core/operations.hpp but that the definition is not being linked to despite the fact that I have the opencv_core320d.lib in my linker. I am using CMake, VS2015, and on Windows 10. Any help would be much appreciated! |
