无法在linux中编译opencv

Question

我一直在尝试使用linux中的g ++编译opencv示例代码的一些示例但我运行后收到此错误消息:

g++ `pkg-config --cflags --libs opencv` hello.cpp -o hello

我得到这个输出:

/tmp/ccjvVxLI.o: In function `main':
hello.cpp:(.text+0x45): undefined reference to `cvLoadImage'
hello.cpp:(.text+0x6b): undefined reference to `cvNamedWindow'
hello.cpp:(.text+0x7c): undefined reference to `cvShowImage'
hello.cpp:(.text+0x86): undefined reference to `cvWaitKey'
hello.cpp:(.text+0x90): undefined reference to `cvDestroyWindow'
collect2: ld returned 1 exit status

我已经在线查看并检查了我的OpenCV安装,我获得了正常的输出:

pkg-config --cflags opencv

如:

-I/usr/local/include/opencv -I/usr/local/include  

但当我跑:

pkg-config --libs opencv

我有一个奇怪的列表,看起来像这样:

/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_photo.so /usr/local/lib/libopencv_stitching.so /usr/local/lib/libopencv_ts.so /usr/local/lib/libopencv_video.so /usr/local/lib/libopencv_videostab.so 

如果有帮助我在本网站的帮助下在ubuntu LTS 12.04上安装了Opencv2.4.1:http://www.samontab.com/web/2012/06/installing-opencv-2-4-1-ubuntu-12-04 -lts /

试试这个:

g++ `pkg-config --cflags opencv` -o hello hello.cpp `pkg-config --libs opencv`
