我正在尝试使用带有opencv的树莓派相机板来测试示例。该代码来自https://github.com/robidouille/robidouille/blob/master/raspicam_cv/RaspiCamCV.c
键入make时出现错误：
未定义对符号cvSaveImage的引用
我有包含函数cvSaveImage的标头。当我不使用cvSaveImage时，它将成功编译。
我怎么知道缺少图书馆？这是我的pkg-config opencv --libs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在/usr/local/lib/libopencv_imgcodecs.so.3.0.0中。我有一个makefile，但我不知道如何解决该错误。
最佳答案
查看pkg-config opencv --libs的输出，找出缺少的库，然后将它们添加到配置中。有关更多信息，请访问OpenCV 2.4.1 undefined references
