我正在开发一个插件捆绑包,说应用程序的MyPlugIn.bundle,说BigApp.app.这个bundle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,就像我为一个简单的应用程序包所做的一样：
$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无法加载该软件包,Mac OS X的Console.app记录如下：
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不被MyPlugIn.bundle可执行路径替换,而是由BigApp.app可执行路径替代.
任何解决方法,没有绝对的路径,以便它可以在Mac OS X 10.4(Tiger)上工作？谢谢.
