dylib @executable_path插件包中的路径问题 [英] dylib @executable_path path issue in a plug-in bundle

问题描述

我正在开发插件包，例如针对应用程序的MyPlugIn.bundle ，例如BigApp.app. 此捆绑包需要一个dylib ，例如MyPlugIn.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捆绑包所做的那样:

I am developing a plug-in bundle, say MyPlugIn.bundle for 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:

$ 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记录以下内容:

But BigApp.app fails to load this bundle, and Mac OS X's Console.app logs what follows:

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 不会由MyPlugIn.bundle可执行文件路径代替，而是由 BigApp.app可执行文件路径代替.

It seems that @executable_path is not replaced by the MyPlugIn.bundle executable path but by the BigApp.app executable path.

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

Any workaround to that, without absolute path and so that it will work on Mac OS X 10.4 (Tiger)? Thanks.

推荐答案

在网络上以及其他一些SO问题:使用@loader_path/..而不是@executable_path/...参见:

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