2012-11-07 11:07:03 -0600 | answered a question | OpenCV 2.4.3 MinGW cannot run program I had a similar problem, windows 7, MinGW 4.7.2 (the newest version).Except I could not run any opencv version. Such that after I compiled my code the program just crashes right after execution. Continually receiving errors from libstdc++ and opencv core module. I downloaded the libstdc++ from http://www.2shared.com/complete/44qu1Jl9/libstdc-6.html (which I happen to stumble upon). I replaced my current libstdc++ with the downloaded one, this resolved the crashes and opencv seems to be working now. It seems there is some problem with MinGW 4.7.x libstdc++ and windows 7. As this is not the first post of opencv/mingw/windows7 that appeared recently on the net. Hope this helps :) |
2012-11-07 10:00:14 -0600 | asked a question | OpenCV2.4.2 crash Windows 7 Good day OpenCV is crashing. I can build successfully, I can even run IplImage and cvCreateImage but as soon as I use the Windows interface such as displaying an image the program crashes with problem at libstdc++-6. I have tried an older version of OpenCV and experience the same problem. Any suggestions? |

2012-09-08 06:20:47 -0600 | asked a question | OpenCV2.4.2 and IPL_DEPTH_1U Good day I know that OpenCV did not always support IPL_DEPTH_1U. I just want to know if all functions support IPL_DEPTH_1U now. Such as cvErode etc. Like in cvFindContours they specify only 8 bit images, is that correct? Regards |

2012-07-16 05:58:44 -0600 | asked a question | findHomography gives an error libstdc++-6.dll entry point missing Good day When using the function findHomography( obj, scene, CV_RANSAC ) the following error occur: "The procedure entry point __ZNSt8__detail15_List_node_base11_M_transferEPS0_S1_ could not be located in the dynamic link library libstdc++-6.dll." I am running Windows7, MinGW, Codeblocks and Opencv2.4 and using the code: http://docs.opencv.org/doc/tutorials/features2d/feature_homography/feature_homography.html Except for the include which I use: if I use the include in the code the SurfFeatureDetector becomes undeclared with various other functions.
