OpenCV找不到highgui

Question

我正在嘗試編譯一個opencv文件，但是似乎找不到highgui庫

g++ -O2 -W -Wall -lhighgui tracking.cc -o tracking
/usr/bin/ld: cannot find -lhighgui
collect2: error: ld returned 1 exit status

任何想法如何解決這個問題？

我試過了

updatedb
ldconfig
g++ -O2 -W -Wall -L/usr/lib/libopencv_highgui.so tracking.cc -o tracking

但似乎沒有任何效果。

編輯：發出pkg-config --libs --cflags opencv返回：

-I/usr/local/include/opencv -I/usr/local/include  /usr/local/lib/libopencv_calib3d.so /usr/local/lib/libopencv_contrib.so /usr/local/lib/libopencv_core.so /usr/local/lib/libopencv_features2d.so /usr/local/lib/libopencv_flann.so /usr/local/lib/libopencv_gpu.so /usr/local/lib/libopencv_highgui.so /usr/local/lib/libopencv_imgproc.so /usr/local/lib/libopencv_legacy.so /usr/local/lib/libopencv_ml.so /usr/local/lib/libopencv_nonfree.so /usr/local/lib/libopencv_objdetect.so /usr/local/lib/libopencv_ocl.so /usr/local/lib/libopencv_photo.so /usr/local/lib/libopencv_stitching.so /usr/local/lib/libopencv_superres.so /usr/local/lib/libopencv_ts.a /usr/local/lib/libopencv_video.so /usr/local/lib/libopencv_videostab.so -lrt -lpthread -lm -ldl

確定找到了解決方案，只需將我的代碼放入opencv的示例目錄中，並命名為buildall.sh

另外，不建議使用opencv，但最好是每次手動鏈接。
