Ubuntu 奇怪的opencv.pc（pkg config）文件

我在Ubuntu 12.04 64位上构建了opencv。如果发出以下命令，我可以链接到opencv库：

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

gcc -g -O2 -W -Wall -Wno-unused -Wno-multichar  -o main main.o -lcxcore -lcv -lhighgui -lcvaux 

但是，如果我发出以下命令：

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

gcc -g -O2 -W -Wall -Wno-unused -Wno-multichar  -o main main.o -lcxcore -lcv -lhighgui -lcvaux 

我得到：

/usr/bin/ld: cannot find -lcxcore
/usr/bin/ld: cannot find -lcv
/usr/bin/ld: cannot find -lhighgui
/usr/bin/ld: cannot find -lcvaux
collect2: ld returned 1 exit status

要解决我发布的问题，请执行以下操作：

pkg-config --libs opencv 

得到：

/usr/local/lib/libopencv_calib3d.so/usr/local/libopencv_contrib.so/usr/local/libopencv_core.so/usr/local/lib/libopencv_features2d.so/usr/local/libopencv_flann.so/usr/local/libopencv_gpu.so/usr/local/libopencv\u highgui.so/usr/local/libopencv/libopencv\u imgproc.so/usr/local/libopencv/lib/lib/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/libopencv_stching.so/usr/local/libopencv_ts.so/local/libopencv_video.so/usr/local/libopencv\u videostab.so

我想这就解释了这个问题，但我不明白为什么opencv.pc没有像普通的.pc文件那样包含库位置的速记llib格式。有什么想法吗？

您需要包括pkg config提供给您的库头的位置

pkg-config opencv --cflags

对我来说，输出是

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

如果你加上这个，它应该可以正常工作
