我试图使用带有opencv的raspberry pi相机板测试一个例子。代码来自https://github.com/robidouille/robidouille/blob/master/raspicam_cv/RaspiCamCV.c
输入make时出错：
对符号
的未定义引用cvSaveImage
我的标题包含函数cvSaveImage。当我不使用cvSaveImage时，它会成功编译。
我怎么知道图书馆丢失了？这是pkg-config opencv --libs的输出：
/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 / usr / local / lib / libopencv_viz.so /usr/lib/x86_64-linux-gnu/libXext.so /usr/lib/x86_64-linux-gnu/libX11.so /usr/lib/x86_64-linux-gnu/libICE.so / usr / lib / x86_64-linux-gnu / libSM.so /usr/lib/x86_64-linux-gnu/libGL.so /usr/lib/x86_64-linux-gnu/libGLU.so -ltbb -lrt -lpthread -lm -ldl
更新：cvSaveImage位于/usr/local/lib/libopencv_imgcodecs.so.3.0.0。我有一个makefile，但我不知道如何从中解决错误。
