我正在尝试将 Google Breakpad（一些外部框架）支持添加到我的应用程序中。我已经完成了所有必需的步骤，但是当我尝试使用 dlopen 加载我的应用程序时，我收到了这个错误：

(char *) error = 0x0000000100200175 "dlopen(/Users/user/MyApp.app/Contents/MacOS/MyApp, 1): 
Library not loaded: @executable_path/../Frameworks/Breakpad.framework/Versions/A/Breakpad\n  
Referenced from: /Users/user/MyApp.app/Contents/MacOS/MyApp\n  
Reason: image not found"

我检查了一下，Breakpad 文件确实存在于相对路径（到 MyApp 文件）中。

这是 MyApp 文件上的 otool -L （注意@executable_path）：

Users-Mac:MacOS user$ otool -L MyApp

有人有线索吗？

请按照以下步骤操作，它可能会起作用：

  1. 转到目标然后按构建阶段
  2. 这个页面的左上角你会发现+符号，按这个符号。
  3. 按新建复制文件构建阶段
  4. 展开复制文件，然后将您的框架拖放到此部分中。
  5. 将目标更改为框架

希望它会工作

好吧，事实证明，在使用动态库和为 OS X 10.6 编译时，这是一个问题。@executable_path 在动态加载后不会更新，因此 LOADED 二进制文件正在寻找其相对于 LOADING 二进制文件的依赖项。

我最终重新编译了我的框架 Breakpad，并使用 @loader_path 而不是 @executable_path，现在一切正常。
