我刚刚在 Debian 机器上安装了 OpenCV，但遇到了问题。我按照 Wiki 上的安装指南进行操作。尝试编译这些示例似乎可以成功编译，但是尝试运行它们最终会抛出错误：
fagg@hubble:~/src/OpenCV-2.3.1/samples/cpp$ g++ -Wall em.cpp
-lopencv_core -lopencv_imgproc -lopencv_calib3d -lopencv_video
-lopencv_features2d -lopencv_ml -lopencv_highgui -lopencv_objdetect
-lopencv_contrib -lopencv_legacy
fagg@hubble:~/src/OpenCV-2.3.1/samples/cpp$ ./a.out
./a.out: error while loading shared libraries: libopencv_core.so.2.3:
cannot open shared object file: No such file or directory
fagg@hubble:~/src/OpenCV-2.3.1/samples/cpp$ pkg-config opencv
--libs-L/usr/local/lib -lopencv_core -lopencv_imgproc -lopencv_highgui
-lopencv_ml -lopencv_video -lopencv_features2d -lopencv_calib3d
-lopencv_objdetect -lopencv_contrib -lopencv_legacy -lopencv_flann
fagg@hubble:~/src/OpenCV-2.3.1/samples/cpp$
但即使这样做也不起作用：
fagg@hubble:~/src/OpenCV-2.3.1/samples/cpp$ g++ -Wall em.cpp
`pkg-config opencv --cflags --libs`
fagg@hubble:~/src/OpenCV-2.3.1/samples/cpp$ ./a.out
./a.out: error while loading shared libraries: libopencv_core.so.2.3:
cannot open shared object file: No such file or directory
fagg@hubble:~/src/OpenCV-2.3.1/samples/cpp$
我认为链接有问题，但我不太确定发生了什么。这是 OpenCV 的全新安装 - 我以前从未在这台机器上安装过它。有人有什么想法吗？
