How to install and split OpenCV dylib to the single project
官网下载OpenCV源码： http://opencv.org
#!/bin/bash mkdir build cd build cmake -G "Unix Makefiles" .. make j8 sudo make install
- 到此OpenCV成功安装到Mac平台，现在可以基于OpenCV库来进行开发。
- 以OpenCV_2.4.10 版本为例, 在代码中通过System.load()加载的OpenCV动态库为libopencv_java2410.dylib, 获取路径为/usr/local/share/OpenCV/java/, 可以copy到工程路径中去
- 开发完成之后对于用Java开发而言要打包成runnable jar 包，还需要把OpenCV(libopencv_java2410.dylib)依赖的相关动态库取出来放到jar包里去，具体操作如下: 打开/usr/local/share/OpenCV/java/, 运行命令：
otool -L libopencv_java2410.dylib
结果输出：
libopencv_java2410.dylib: lib/libopencv_java2410.dylib (compatibility version 0.0.0, current version 0.0.0) lib/libopencv_contrib.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) lib/libopencv_nonfree.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) lib/libopencv_gpu.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) lib/libopencv_legacy.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) lib/libopencv_photo.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) lib/libopencv_ocl.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) lib/libopencv_calib3d.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) lib/libopencv_features2d.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) lib/libopencv_flann.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) lib/libopencv_ml.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) lib/libopencv_video.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) lib/libopencv_objdetect.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) lib/libopencv_highgui.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) lib/libopencv_imgproc.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) lib/libopencv_core.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) /usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 120.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1213.0.0)
然后打开/usr/local/lib, copy出libopencv_*.dylib的实体dylib文件(非软连接文件)到 runnable jar包应用中的某一个路径文件夹中， 并把文件名称改成与步骤a)结果输出中一致 然后运行如下Shell脚本：
CV_LIB_PATH=/Applications/iTestin.app/Contents/Jar/tools/OpenCV/mac/dylib
LOAD_LIB_PATH=@loader_path
find ${CV_LIB_PATH} -type f -name "libopencv*.dylib" -print0 | while IFS="" read -r -d "" dylibpath; do
install_name_tool -id "$dylibpath" "$dylibpath"
otool -L $dylibpath | grep libopencv | tr -d ':' | while read -a libs ; do
[ "${file}" != "${libs[0]}" ] && install_name_tool -change ${libs[0]} ${LOAD_LIB_PATH}/`basename ${libs[0]}` $dylibpath
done
done
执行完成之后进入到工具路径下，执行otool -L *查看相关动态库的链接路径是否改变(以libopencv_calib3d.2.4.dylib为例)：
libopencv_calib3d.2.4.dylib: lib/libopencv_calib3d.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) @loader_path/libopencv_features2d.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) @loader_path/libopencv_flann.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) @loader_path/libopencv_highgui.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) @loader_path/libopencv_imgproc.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) @loader_path/libopencv_core.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) /usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 120.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1213.0.0)
- 最后再次执行命令 otool -L libopencv_java2410.dylib， 查看路径是否改变： 输出结果：
libopencv_java2410.dylib: lib/libopencv_java2410.dylib (compatibility version 0.0.0, current version 0.0.0) @loader_path/dylib/libopencv_contrib.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) @loader_path/dylib/libopencv_nonfree.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) @loader_path/dylib/libopencv_gpu.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) @loader_path/dylib/libopencv_legacy.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) @loader_path/dylib/libopencv_photo.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) @loader_path/dylib/libopencv_ocl.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) @loader_path/dylib/libopencv_calib3d.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) @loader_path/dylib/libopencv_features2d.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) @loader_path/dylib/libopencv_flann.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) @loader_path/dylib/libopencv_ml.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) @loader_path/dylib/libopencv_video.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) @loader_path/dylib/libopencv_objdetect.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) @loader_path/dylib/libopencv_highgui.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) @loader_path/dylib/libopencv_imgproc.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) @loader_path/dylib/libopencv_core.2.4.dylib (compatibility version 2.4.0, current version 2.4.10) /usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 120.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1213.0.0)
全部更改完成，到此导出的包可以在生产环境的Mac机器上运行
