/usr/bin/ld编译OPENCV MATLAB源时找不到LIB文件

Question

我在尝试使用MATLAB模块编译OpENCV时会遇到以下错误。

我刚刚在我在opencv.org的教程中创建的REALSE文件夹中运行$ MAKE

    [ 98%] Compiling Matlab source files. This could take a while...
    CMake Error at /home/alex/Downloads/opencv-master/modules/matlab/compile.cmake:47 (message):
    Failed to compile drawChessboardCorners: /usr/bin/ld: cannot find
      -lopencv_core
  /usr/bin/ld: cannot find -lopencv_imgproc
  (Removed alot of lines with lib files here)
  collect2: error: ld returned 1 exit status

      mex: link of ' "drawChessboardCorners.mexa64"' failed.

如何修复链接错误？它与matlab有关吗？

Answer 1

我认为这与Matlab无关。：

/usr/bin/ld: cannot find

指向链接器在编译过程中无法找到的opencv_core库的缺失路径。请参阅：usr/bin/ld：找不到-l＆lt; nameofthelibrary＆gt;

如果您是手动构建的，则可以添加-L选项，例如

-L<path_to_opencv_core>在-lopencv_core或-lopencv_imgproc

之前

到命令行构建命令。如果您使用的是CMAKE文件，则可以设置${OPENCV_LIB_INSTALL_PATH}（或类似的内容），例如，使用ccmake.
