链接器错误，在Ubuntu 15.04上使用OpenCV和Eclipse CDT

Question

I'm going step by step like this guide and my code does not compile. It has gotten some linker errors which I don't know how to fix. this is my terminal's answer to : pkg-config --libs opencv

/usr/lib/x86_64-linux-gnu$ pkg-config --libs opencv /usr/lib/x86_64-linux-gnu/libopencv_calib3d.so -lopencv_calib3d /usr/lib/x86_64-linux-gnu/libopencv_contrib.so -lopencv_contrib /usr/lib/x86_64-linux-gnu/libopencv_core.so -lopencv_core /usr/lib/x86_64-linux-gnu/libopencv_features2d.so -lopencv_features2d /usr/lib/x86_64-linux-gnu/libopencv_flann.so -lopencv_flann /usr/lib/x86_64-linux-gnu/libopencv_gpu.so -lopencv_gpu /usr/lib/x86_64-linux-gnu/libopencv_highgui.so -lopencv_highgui /usr/lib/x86_64-linux-gnu/libopencv_imgproc.so -lopencv_imgproc /usr/lib/x86_64-linux-gnu/libopencv_legacy.so -lopencv_legacy /usr/lib/x86_64-linux-gnu/libopencv_ml.so -lopencv_ml /usr/lib/x86_64-linux-gnu/libopencv_objdetect.so -lopencv_objdetect /usr/lib/x86_64-linux-gnu/libopencv_ocl.so -lopencv_ocl /usr/lib/x86_64-linux-gnu/libopencv_photo.so -lopencv_photo /usr/lib/x86_64-linux-gnu/libopencv_stitching.so -lopencv_stitching /usr/lib/x86_64-linux-gnu/libopencv_superres.so -lopencv_superres /usr/lib/x86_6 4-linux-gnu/libopencv_ts.so -lopencv_ts /usr/lib/x86_64-linux-gnu/libopencv_video.so -lopencv_video /usr/lib/x86_64-linux-gnu/libopencv_videostab.so -lopencv_videostab

sorry if it's a mess to read but this is exactly how I received the answer.

This is how I've organized my linker

this is the error I get:

Building target: Ball_Plate Invoking: GCC C++ Linker g++ -L/usr/lib/x86_64-linux-gnu -o"Ball_Plate" ./Src/src.o -lopencv_core\\ opencv_imgproc\\ opencv_highgui\\ opencv_ml\\ opencv_video\\ opencv_features2d\\ opencv_calib3d\\ opencv_objdetect\\ opencv_contrib\\ opencv_legacy\\ opencv_flann /usr/bin/ld: cannot find -lopencv_core opencv_imgproc opencv_highgui opencv_ml opencv_video opencv_features2d opencv_calib3d opencv_objdetect opencv_contrib opencv_legacy opencv_flann collect2: error: ld returned 1 exit status makefile:45: recipe for target 'Ball_Plate' failed make: *** [Ball_Plate] Error 1

I don't know how to fix this, I don't know much about how linker works around .so files and I would appreciate that if you could help me.

因此，我阅读了这篇文章，并找出了问题所在，尝试使用-DBUILD_TIFF=ON编译OpenCV库，现在Eclipse可以找到头文件了，但是我又遇到了链接器错误，Eclipse无法链接库。
