Question

我写了一个关键取决于OpenCV的程序。我已经从最新的稳定版本编译了OpenCV，现在想分发这个程序，以确保人们不需要自己编译OpenCV。程序本身使用g ++编译。

我尝试了很多方法来解决这个问题：

编译OpenCV作为静态库工作，但我不能静态地将我的程序链接到这些库，因为OS X中的某些库不能静态链接;我在此处找到了此信息：Mixed static and dynamic link on Mac OS
我试图转移到XCode，在那里我将它用作命令行项目。我将搜索路径以及安装位置设置为@rpath，并添加了构建阶段以将文件复制到可执行文件。我用otool验证了编译后的文件是否具有正确的链接，但是在一台干净的机器（没有OpenCV库的机器）上仍然出现故障，并且“找不到库@rpath / libopencv ...”错误。（是的，所有的mac都使用Lion，所以@rpath应该可以工作）。这个答案在这里找到：Xcode keeps searching dylib at wrong path

我从runnig otool -L获得的编译文件和库的结果是 @rpath/libopencv_core.2.4.dylib (compatibility version 2.4.0, current version 2.4.0) /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 52.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 159.1.0)

那么......我做错了什么？我如何将这些库与我的程序一起分发？

Answer 1

您应该使用框架（SO question on frameworks）。将您的应用程序使用的所有内容合并到一个文件夹中，然后链接到XCode项目中的框架。

我最近必须这样做才能在applet中运行JavaCV。这个命令应该完成工作：

BADPATH=/opt/local/lib  # in the case of MacPorts, change as necessary
for f in libopencv*2.4.dylib; do install_name_tool $f -id @rpath/$f \
    -add_rpath /opt/local/lib/ -add_rpath /usr/local/lib/ -add_rpath @loader_path/. \
    -change $BADPATH/libopencv_core.2.4.dylib @rpath/libopencv_core.2.4.dylib \
    -change $BADPATH/libopencv_calib3d.2.4.dylib @rpath/libopencv_calib3d.2.4.dylib \
    -change $BADPATH/libopencv_features2d.2.4.dylib @rpath/libopencv_features2d.2.4.dylib \
    -change $BADPATH/libopencv_flann.2.4.dylib @rpath/libopencv_flann.2.4.dylib \
    -change $BADPATH/libopencv_gpu.2.4.dylib @rpath/libopencv_gpu.2.4.dylib \
    -change $BADPATH/libopencv_highgui.2.4.dylib @rpath/libopencv_highgui.2.4.dylib \
    -change $BADPATH/libopencv_imgproc.2.4.dylib @rpath/libopencv_imgproc.2.4.dylib \
    -change $BADPATH/libopencv_legacy.2.4.dylib @rpath/libopencv_legacy.2.4.dylib \
    -change $BADPATH/libopencv_ml.2.4.dylib @rpath/libopencv_ml.2.4.dylib \
    -change $BADPATH/libopencv_nonfree.2.4.dylib @rpath/libopencv_nonfree.2.4.dylib \
    -change $BADPATH/libopencv_objdetect.2.4.dylib @rpath/libopencv_objdetect.2.4.dylib \
    -change $BADPATH/libopencv_photo.2.4.dylib @rpath/libopencv_photo.2.4.dylib \
    -change $BADPATH/libopencv_video.2.4.dylib @rpath/libopencv_video.2.4.dylib; done

并使用这些和所需的“-rpath”选项重新链接您的软件。
