I tried with other Opencv version and all of them dont have opencvworld. Now go back to your desktop and type: Windows. I dont understand, even building opencvworld with cmake correctly, there isnt any opencvworld.lib (mine should be opencvworld460.lib). Seems like doing a GPU build would need to be very specific to where the CUDA libs are living on someone’s machine, so it might be better just have instructions for doing it than trying to include it in the static lib. Once, there you will click on the green Clone or download button and copy the link that appears. Not sure if this will fix it but you can try. If you see OpenCV.lib in the Additional Dependencies field, remove it. B build Actually build the binaries cmake -build build -config Release in your source directory. I’m not having much luck getting the static lib built with ar or libtool so I’m not sure what process was used to put it together. Check your project properties by going to Project->Properties and see that your Linker->Input tab doesnt have any dependencies for OpenCV. Following up the Suthiros answer, you can also explicitly specify Debug or Release configurations for multi-configuration generators (Ninja Multi-Config, Visual Studio) by running Configure the build cmake -S. Apparently CUDA 3.0 & 3.2 don’t work with oCV so you’ll need set 4.0 in the CMake file and check that the output from CMake says: However, to simplify the process, we suggest that you download. I had thought I was compiling it with GPU support, but I apparently wasn’t. The first approach involves compiling the GLFW source code directly with CMake for full control. I got OpenCV2.3 compiled with GPU support, which involved getting the SDK (didn’t have that already). Lets get started with an example: We are going to create an MD5 hash calculator app that uses one of the most popular C++ libraries: Poco. Users/theo/Documents/CODE/_OPENFRAMEWORKS/gitOF/_BuildAllLibs/OpenCV-2.2.0/modules/gpu/src/precomp.hppThe library is compilled without GPU support%s:%d: error: (%d) %s in function %s 1.The error occurred when build both release and debug for 'allbuild' in opencv solution that generated by CMake. Std::cout << "Error: " << ex.what() << std::endl Īnd this time getting: fatal error C1083: Cannot open include file: 'opencv2/opencv_modules.Check through the openCV.a I think it has the same problem that my original oCV build had: gpu files included but not actually working. lib files are located (in the ‘Additional Library Directories’ section) (C:\Program Files (x86)\Windows Kits\10\Lib\1.0\um\圆4 C:\Program Files (x86)\Windows Kits\10\Lib\1.0\ucrt\圆4): and after building the project again in Debug 圆4, it succeeds VS2022 Output window shows this. Then, I set the following as it was in every tutorial:Īnd finally, this is the piece of code I am trying to build (yes, I need GPU support): #include Ĭv::Mat src_host = cv::imread("hdd.png", CV_LOAD_IMAGE_GRAYSCALE) Ĭv::gpu::threshold(src, dst, 128.0, 255.0, CV_THRESH_BINARY) I made the required changes in the properties: VC++ directories: the path to the static include files, Linker->General-> additional Library directories: the path to the static libraries, Linker->input->additional Dependencies (here debug and release resp: opencvworld460d.lib and opencvworld460.lib). I added the following to my environment variable and PATH, respectively: C:\opencv\build\install\圆4\vc12 I used CMAKE and VS to build and install. So I built everything from the source which I got from official Github page of OpenCV. (Haven't added anything to user variables, FYI) ImportError: libavcodec.so.56: cannot open shared object file: No such file or directory. error while loading shared libraries: libstdc++.so.6.0.20: cannot open shared object file: No such. But with C.C 3.5 i faced issue using V.S 2019 that it should be compiled with VS (13 - 17). load(/usr/local/lib/libOpenCV/java/opencvjava2410.so). Before this, I have succesfully build the opencv for GPU with cuda compatibility of 8.5 on VS 2019. If that is the only thing to do there, this should be fine. On opening the file OpenCV.sln with VS 2015, I perfomed Build to ALLBUILD under CMakeTargets. fatal error LNK1181: cannot open input file 'opencv_world311.lib' In CMAKE 3.26. I have followed this tutorial regarding installing OpenCV 3.0.0 with VS13 and I am trying to make my OpenCV 3.3.1 work but no luck, looked for 2 hours for a remedy, followed tons of tutorials but I keep getting the same error.
