我正在尝试使用带有 opencv 的树莓派相机板来测试一个示例。代码来自https://github.com/robidouille/robidouille/blob/master/raspicam_cv/RaspiCamCV.c
当输入 make 时，我收到错误:
Undefined reference to symbol
cvSaveImage
我有包含函数cvSaveImage的 header 。当我不使用 cvSaveImage 时，它会成功编译。
我如何知道缺少哪些库？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位于/usr/local/lib/libopencv_imgcodecs.so.3.0.0中。我有一个 makefile，但我不知道如何解决其中的错误。
最佳答案
查看 pkg-config opencv --libs 的输出以找出您缺少的库，然后将它们添加到您的配置中。欲了解更多信息，请访问OpenCV 2.4.1 undefined references
