Статическая библиотека Opencv не может быть связана в eclipse (-ldl добавлен!)
Я добавил два метода в детектор Лалита Пателя:
- addFont (family, stylesheetUrl, ruleString) -> обнаруживает, существует ли «семейство» шрифта, если не добавляет таблицу стилей, загружающую шрифт используя либо stylesheetUrl, если задано, либо иначе ruleString
- addFontsArr (arr) -> добавляет массив шрифтов
С помощью этого вы можете сделать:
fonts = [ 'Arial', 'Arial Black', { family: 'Lato', stylesheetUrl: 'https://fonts.googleapis.com/css?family=Lato'}, 'Leelawadee UI']
(new FontDetector()).addFontsArr(fonts);
код:

Наконец-то статически связал opencv и затмение! Я использовал Opencv Cuda, IPP, ffmpeg и многие другие библиотеки, так что есть больше библиотек для включения!
GCC C ++ линкера: Библиотеки (-l): opencv_cudabgsegm, opencv_cudaobjdetect, opencv_cudastereo, opencv_stitching, opencv_cudafeatures2d, opencv_superres, opencv_cudacodec, opencv_videostab, opencv_cudaoptflow, opencv_cudalegacy, opencv_cudawarping, opencv_aruco, opencv_bgsegm, opencv_bioinspired, opencv_ccalib, opencv_cvv, opencv_dnn_objdetect, opencv_dpm, opencv_face, opencv_photo, opencv_cudaimgproc, opencv_cudafilters, opencv_freetype, opencv_fuzzy, opencv_hdf, opencv_hfs, opencv_img_hash, opencv_line_descriptor, opencv_optflow, opencv_reg, opencv_rgbd, opencv_saliency, opencv_stereo, opencv_structured_light, opencv_phase_unwrapping, opencv_surface_matching, opencv_tracking, opencv_datasets, opencv_text, opencv_dnn, opencv_plot, opencv_xfeatures2d, opencv_shape, opencv_video, opencv_ml, opencv_cudaarithm, opencv_ximgproc, opencv_calib3d, opencv_features2d, opencv_highgui, opencv_videoio, opencv_flann, opencv_xobjcvc_vcc_vcc_vcc_vccvcvtcvg _imgproc, opencv_core, opencv_cudev, libprotobuf, GLU, GL, gstpbutils-1.0, gstriff-1.0, gstapp-1.0, gstvideo-1.0, gstbase-1.0, gstreamer-1.0, gobject-2.0, glib-2.0, avcodec, avformat, sw, формат avutil, avfilter, swresample, avresample, avdevice, postproc, m, z, x264, lzma, rt, dc1394, tbb, gphoto2_port, gphoto2, xine, jpeg, webp, png, tiff, jasper, Imath, hdf5, lept, sz, IlmImf, cudart, nppc, nppial, nppicc, nppicom, nppidei, nppif, nppig, nppim, nppist, nppisu, nppitc, npps, cublas, cufft, ippiw, ippicv, ittnotify, dl, поиск по пути

Если вы хотите узнать, какую библиотеку вам нужно включить, вы можете посмотреть общую конфигурацию, которая выглядит как приведенный ниже скрипт ( * появляются при сборке opencv) и включают каждую библиотеку в скрипте в программу, с которой вы хотите связать opencv sta тически.
