I am trying to get a version of GoCV that works with OpenCV static libraries. The final issue I have is that pkg-config is not really listing all required libraries so i need to append some extra ones. Here is how my cgo configuration looks like without the extra libraries:
#cgo !windows pkg-config: --static opencv4 #cgo CXXFLAGS: --std=c++11 This mostly works but, as I mentioned, pkg-config -static is somehow missing some libraries and I have to add then. because I am dealing with static libraries, it is important that they are all added after all the other -llibrary entries. I tried adding the libraries after the last #cgo statement, like this: #cgo !windows pkg-config: --static opencv4 #cgo CXXFLAGS: --std=c++11 #cgo !windows LDFLAGS: -ldc1394 -lavcodec -lavformat -lavutil -lswscale This correctly adds the libraries to the linker command but the libraries are added before any other entries. i.e, here is what I get: TERM='dumb' g++ -I . -fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=$WORK/b031=/tmp/go-build -gno-record-gcc-switches -o $WORK/b031/_cgo_.o $WORK/b031/_cgo_main.o $WORK/b031/_x001.o $WORK/b031/_x002.o $WORK/b031/_x003.o $WORK/b031/_x004.o $WORK/b031/_x005.o $WORK/b031/_x006.o $WORK/b031/_x007.o $WORK/b031/_x008.o $WORK/b031/_x009.o $WORK/b031/_x010.o $WORK/b031/_x011.o $WORK/b031/_x012.o $WORK/b031/_x013.o $WORK/b031/_x014.o $WORK/b031/_x015.o $WORK/b031/_x016.o $WORK/b031/_x017.o $WORK/b031/_x018.o $WORK/b031/_x019.o $WORK/b031/_x020.o $WORK/b031/_x021.o $WORK/b031/_x022.o $WORK/b031/_x023.o $WORK/b031/_x024.o $WORK/b031/_x025.o -g -O2 -ldc1394 -lavcodec -lavformat -lavutil -lswscale -ldc1394 -lavcodec -L/usr/local/lib -L/usr/local/lib/opencv4/3rdparty -L/tmp/opencv/opencv-4.1.2/build/lib -lopencv_gapi -lopencv_stitching -lopencv_aruco -lopencv_bgsegm -lopencv_bioinspired -lopencv_ccalib -lopencv_dnn_objdetect -lopencv_dnn_superres -lopencv_dpm -lopencv_highgui -lopencv_face -lopencv_freetype -lopencv_fuzzy -lopencv_hfs -lopencv_img_hash -lopencv_line_descriptor -lopencv_quality -lopencv_reg -lopencv_rgbd -lopencv_saliency -lopencv_stereo -lopencv_structured_light -lopencv_phase_unwrapping -lopencv_superres -lopencv_optflow -lopencv_surface_matching -lopencv_tracking -lopencv_datasets -lopencv_text -lopencv_dnn -lopencv_plot -lopencv_videostab -lopencv_video -lopencv_videoio -lopencv_xfeatures2d -lopencv_shape -lopencv_ml -lopencv_ximgproc -lopencv_xobjdetect -lopencv_objdetect -lopencv_calib3d -lopencv_imgcodecs -lopencv_features2d -lopencv_flann -lopencv_xphoto -lopencv_photo -lopencv_imgproc -lopencv_core -littnotify -llibprotobuf -llibwebp -lIlmImf -lquirc -lippiw -lippicv -lade -lgtk-x11-2.0 -lgdk-x11-2.0 -lpangocairo-1.0 -latk-1.0 -lcairo -lgdk_pixbuf-2.0 -lgio-2.0 -lpangoft2-1.0 -lpango-1.0 -lgobject-2.0 -lglib-2.0 -lfontconfig -lgthread-2.0 -ljpeg -lpng -lz -ltiff -lfreetype -lharfbuzz -ldl -lm -lpthread -lrt This fails.
