你有办法解决这个问题吗？在

Answer 1

你的答案就在垃圾堆里： _psutil公司_osx公司（来自/Users/user/Public/Drop Box/SafeDrive.app/Contents/Resources/)在

在运行时使用dlopen（）时，缺少它试图从libSystem.B导入的符号strlcat_chk。\u Chk变量是strlcat（字符串连接函数）的一个更安全的版本，它检查参数是否有缓冲区溢出。使用特定版本的XCode和更高版本构建的应用程序将默认使用此函数，而不是strlcat。它是小牛LibC的一部分，我相信是997版本。在

如果您有该共享对象的源代码，请将\u chk更改为非检查符号版本（即strlcat），这样就可以修复它。否则，您可以尝试修补二进制文件的字符串表（假设它不违反代码签名，如果有的话）。您可以使用-mminosx版本10.7（甚至10.6）重新编译，这可能会解决问题。在
