dylib @executable_path path issue in a plug-in bundle
提问by moala
I am developing a plug-in bundle, say MyPlugIn.bundlefor an application, say BigApp.app. This bundle requires a dylib, say MyPlugIn.bundle/Contents/Resources/library.dylib. I have relocated paths for library.dylib, as I would have done for a simple application bundle:
我正在开发一个插件包，比如说MyPlugIn.bundle一个应用程序，比如说BigApp.app。这个包需要一个 dylib，比如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)
[...]
But BigApp.app fails to load this bundle, and Mac OS X's Console.app logs what follows:
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
It seems that @executable_pathis not replaced by the MyPlugIn.bundle executable path but by the BigApp.app executable path.
似乎 @executable_path没有被 MyPlugIn.bundle 可执行路径替换，而是被BigApp.app 可执行路径替换。
Any workaroundto that, without absolute path and so that it will work on Mac OS X 10.4 (Tiger)? Thanks.
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。

From the web and other SO questions: use @loader_path/..instead of @executable_path/... See:
