opencv，使用cmake构建C ++项目时出现链接错误

Question

我试图通过执行以下命令来构建一个c ++项目： make但出现以下错误：

/usr/bin/ld: cannot find -lcv 
/usr/bin/ld: cannot find -lcxcore   
/usr/bin/ld: cannot find -lml

而且我有opencv库：

$ pkg-config --cflags --libs opencv
    -I/usr/include/opencv  -lopencv_calib3d -lopencv_contrib -lopencv_core  
    -lopencv_feathures2d -lopencv_flann -lopencv_gpu -lopencv_highgui     
    -lopencv_imgproc -lopencv_lagecy -lopencv_ml -lopencv_objdetect -lopencv_ocl 
    -lopencv_photo -lopencv_stitching -lopencv_superres -lopencv_ts -lopencv_video                                  
    -lopencv_videostab

Answer 1

这意味着您要求链接程序链接到库“ cv，cxcore，ml”，但链接程序找不到它们。 如BoBTFish所建议； 让pkg-config为您做到这一点：

g++ `pkg-config --libs opencv` etc...
