MAC OS:尽管rpath正确，但未找到动态链接库 我有一个（相对）大的C++程序，它编译和运行在Ubuntu上（使用cGue/TabKin）。 它在mac os上编译良好，但在尝试启动可执行文件时，我收到错误消息： dyld: Library not loaded: <name of library>.dylib Referenced from: <path to executable>/<executable> Reason: image not found

答案来自于一位记者的评论

我需要使用@rpath

实际上MacOSX确实有rpath的概念。10.4之前 只有@executable_路径指向 可执行二进制文件（与加载的任何dylib相反）。 @10.4中引入了loader_路径，允许dylibs加载 依赖项基于它们的位置（而不是 可执行文件-谁知道库在使用什么）

10.5苹果引入@rpath，烘烤到装载机中 二进制文件-可执行文件或库。因此，与其看到： @加载程序\路径/../../Library/Frameworks/blah.dylib您可能会看到 @rpath/Library/Frameworks/blah.dylib

这意味着如果rpath设置为。而且/它会看 ./Library/Frameworks/blah.dylib，然后 /任何库的Library/Frameworks/blah.dylib

你在用Xcode吗？如果是这样，它在这里是什么样子的：Xcode>project>target>buildphases>linklibraries。。。另外，Xcode>目标>生成设置。。。这里有各种库链接我正在针对我的项目中编译的库进行链接，这些库安装在${CMAKE_install_PREFIX}/lib/${MACHTYPE}文件夹中。

otool-D.dylib

在其安装位置的输出是什么？
