dyld未加载原因:未找到图像libopencv_core.2.4.dylib

Question

我仍然是Objective C和Xcode的新手,但我刚刚完成了一个使用openCV的小应用程序libopencv_core.2.4.2.dylib.

当我在另一台机器上打开最终构建的应用程序时,OS X向我抛出了这个错误:

Dyld Error Message:   Library not loaded: */libopencv_core.2.4.dylib  
Referenced from: /Users/USER/Desktop/my
app.app/Contents/MacOS/my app   
Reason: image not found

为什么我的应用在这里寻找2.4而不是2.4.2？

我已经检查过:

我添加了一个新的构建阶段 - >因此将libopencv_core.2.4.2.dylib其复制到应用程序包(通过Xcode中的"Copy Bundle Resources") - libopencv_core.2.4.2.dylib现在位于我的app.app/Resources

我错过了什么？我是否设置了更多的库搜索路径或类似的？

我也做了什么:

install_name_tool -id "@executable_path/../Frameworks/libopencv_core.2.4.2.dylib" libopencv_core.2.4.2.dylib

将dylib复制到Frameworks目录也不起作用:

Library not loaded: @executable_path/../Frameworks/libopencv_core.2.4.2.dylib

不知道现在该做什么-在dylib 是在我的应用程序的框架目录...

otool -L在二进制文件上使用给了我:

我找到了一个更好的解决方案：在 Xcode 中重新编译 openCV 并@executable_path/../Frameworks在构建设置中为您编译的每个 .dylib 设置 - 现在它们.dylibs自己总是“知道它们在哪里”。
