插件包中的dylib @executable_path路径问题

Question

我正在开发一个插件包,说MyPlugIn.bundle 一个应用程序,说BigApp.app.比如说,这个捆绑包需要一个dylibMyPlugIn.bundle/Contents/Resources/library.dylib.我已经重新定位了library.dylib的路径,就像我为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无法加载此捆绑包,Mac OS X的Console.app会记录以下内容:

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不是由MyPlugIn.bundle可执行路径替换,而是由BigApp.app可执行路径替换.

任何解决方法,没有绝对路径,以便它可以在Mac OS X 10.4(Tiger)上运行？谢谢.

从网络和其他SO问题:使用@loader_path/..而不是@executable_path/...看到:
