| 2015-01-07 12:26:52 -0600 | asked a question | videoreader_gpu not recognized Hi! I have build OpenCV 2.4.10 on Win7, 32bits, with CUDA, OpenGL and TBB. When I try to use cv::gpu::VideoReader_GPU method it is not available. I have found several threads with similar questions, most of them unanswered, this is the only useful one, but it did not work for me: http://answers.opencv.org/question/29... Does anybody have any clue? |
| 2015-01-07 10:46:56 -0600 | commented question | VideoReader_GPU not available, but built with NVCUVID? Hi! I am having the same problem. Where did you edit and removed the CUDA_DISABLER line? I found it in video_reader and video_writer. I onnly disabled it in video_reader. Did you find out why is that condition for? Thanks for your help! D! |

| 2015-01-07 05:07:43 -0600 | commented question | Building OpenCV using Visual Studio 2013 OpenGL CUDA and TBB The Intellisense problems disapeared after adding the include algorithm line, so no probs with that. |
| 2015-01-07 04:58:50 -0600 | commented question | Building OpenCV using Visual Studio 2013 OpenGL CUDA and TBB I did, I was thinking about how it affects to building OpenCV |
| 2015-01-07 04:01:49 -0600 | commented question | Building OpenCV using Visual Studio 2013 OpenGL CUDA and TBB Now, I have a bunch of errors regarding Intellisense. I am having trouble to find any information about it. What is Intellisense? |
| 2015-01-07 03:25:07 -0600 | commented question | Building OpenCV using Visual Studio 2013 OpenGL CUDA and TBB More problems: in addition to not finding the tbb libs, there are 2 more errors: error: namespace "std" has no member "max" in project opencv_gpu This did not happened before. This solves the problem: http://code.opencv.org/issues/4084 |
| 2015-01-05 10:35:19 -0600 | commented question | Building OpenCV using Visual Studio 2013 OpenGL CUDA and TBB Not just that. Once I have everything built, no OpenGL support is available. I will send more info shortly |
| 2015-01-05 10:05:14 -0600 | commented question | Building OpenCV using Visual Studio 2013 OpenGL CUDA and TBB Thanks a lot thdarksdfthmn. I am using th ai32 version of TBB. It is just a matter of path: if I correct it when building, it builds OK. |

| 2015-01-05 09:28:13 -0600 | commented question | Building OpenCV using Visual Studio 2013 OpenGL CUDA and TBB Now, the problem is the path given by CMake to find the tbb libs is wrong. |
| 2015-01-05 09:26:40 -0600 | commented question | Building OpenCV using Visual Studio 2013 OpenGL CUDA and TBB I have re ran CMake without CUDA, OpenGL and TBB and it builds OK. I am trying now, with the libs built, to re build with all the options |
| 2015-01-05 09:26:40 -0600 | asked a question | Building OpenCV using Visual Studio 2013 OpenGL CUDA and TBB Hello everybody and happy new year for those under gregorain calendar! I have been trying to build OpenCV 2.4.10 on Windows 7 32bit using Visual Studio 2013 and it has been a real pain. Mostly, I think it is my lack of expertice what is making it so difficult. I have make some achivements but unfortunatelly it is not working 100%. I would like to write a small manual not so focused on the step by step -it can be frustrating when one of those steps fails and you don't know how to reach the next one- and more focused on understanding what is happening on each step, why and what to expect when something goes wrong. I ask for your help, sure you have faced lot of them before and can explain why it is happening. I am downloading 3 to build with CMake 3.0.2 and Visual Studio 2013. I will update this thread as I take steps. My aim is to build 2.4.10 with CUDA, TBB and OpenGL support. And make it work :)
Here, OPENGL libs are found (opengl32 and glu32) and first missing paths appear (TBB_INCLUDE_DIRS), those for TBB_INCLUDE_DIRS, so:
After that configuration process, TBB tab appears in red with LIB_DIR and STDDEF_PATH labels pointed to my TBB folder.
This time, there are no tag in red, and everything seems to be fine. I check the output and GUI OpenGL support is set to Yes, and so is Use TBB (ver 4.3 interface 8002) under Other third-party libraries, so
Files are generated, so
First errors happen when it tries to find the core lib, so I re-run CMake for a simple build, without OpenGL, CUDA or TBB. So, first question is, why is this happening? Should it not build first the core libs and then go ahead with the rest of libs? I will keep updating as answers come and as I keep on going... Thanks a lot everybody! D! |
