Question

我试图编译一个opencv文件，但似乎找不到highgui库

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

知道如何解决这个问题吗？

我试过

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

但似乎没有任何效果......

修改发出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

发出

g ++ pkg-config --libs --cflags opencv -L / usr / local / lib / tracking.cc -o tracking

返回

不知道！

好的找到了解决方案，只需将我的代码放在opencv的samples目录中并调用buildall.sh

单独注意，不建议使用opencv，而是每次手动链接最好。

OpenCV找不到highgui
