我正在开发一个插件包，比如说MyPlugIn.bundle，是为了一个应用程序，比如说BigApp.app。这个包需要一个动态库，比如说MyPlugIn.bundle/Contents/Resources/library.dylib。我已经重新定位了library.dylib的路径，就像我对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无法加载这个bundle，Mac OS X的Console.app记录了以下内容：
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 可执行文件路径所取代，而是被 BigApp.app 可执行路径 取代了。
有没有解决方法可以避免使用绝对路径，同时能在 Mac OS X 10.4（Tiger） 上运行？谢谢。
