xcode - 插件包中的 dylib @executable_path 路径问题

Question

我正在开发 插件包 ，说 MyPlugIn.bundle 申请 ，说 BigApp.app . 这个包需要一个 dylib ，说 MyPlugIn.bundle/Contents/Resources/library.dylib .我已经为 library.dylib 重新定位了路径，就像我对一个简单的应用程序包所做的那样:

$ otool -L MyPlugIn.bundle/Contents/MacOS/MyPlugIn
MyPlugIn.bundle/Contents/MacOS/MyPlugIn:
 @executable_path/../Resources/library.dylib (compatibility version 0.0.0, current version 0.0.0)
 [...]

$ otool -L MyPlugIn.bundle/Contents/Resources/library.dylib
MyPlugIn.bundle/Contents/Resources/library.dylib:
 @executable_path/../Resources/library.dylib (compatibility version 0.0.0, current version 0.0.0)
 [...]

但是 BigApp.app 无法加载此包，Mac OS X 的 Console.app 记录以下内容:

19/01/10 15:42:59 BigApp[51516] Error loading /Library/Application Support/BigApp/Plug-Ins/MyPlugIn.bundle/Contents/MacOS/MyPlugIn:  dlopen(/Library/Application Support/BigApp/Plug-Ins/MyPlugIn.bundle/Contents/MacOS/MyPlugIn, 262): Library not loaded: @executable_path/../Resources/library.dylib
  Referenced from: /Library/Application Support/BigApp/Plug-Ins/MyPlugIn.bundle/Contents/MacOS/MyPlugIn
  Reason: image not found

似乎@executable_path 没有被 MyPlugIn.bundle 可执行路径替换，而是被 BigApp.app 可执行路径 .

任意 解决方法 到那个，没有绝对路径，所以它会在 上工作Mac OS X 10.4 (Tiger) ?谢谢。

来自网络和其他 SO 问题:使用 @loader_path/..而不是 @executable_path/.. .见:
