OSX10.9 应用崩溃：未找到符号：___strlcat_chk
我有一个应用程序，在我的MacBook（Mavericks系统）上运行得很好。
但是当我在一个虚拟机上（OSX Lion系统）尝试它时，程序崩溃了，并出现了这个错误信息：

你有什么办法可以解决这个问题吗？

你的问题的答案就在这里：
_psutil_osx.so（来自 /Users/user/Public/Drop Box/SafeDrive.app/Contents/Resources/）
缺少了一个叫做 strlcat_chk 的符号，它在运行时试图从 libSystem.B 导入。这个 _Chk 版本是 strlcat（一个字符串连接函数）的安全版本，它会检查参数是否会导致缓冲区溢出。用某个版本的 XCode 及以后的版本构建的应用程序默认会使用这个函数，而不是 strlcat。这个函数是 Mavericks 系统中 LibC 的一部分，我记得是版本 997。
如果你有这个共享对象的源代码，可以把 _chk 改成不检查的版本（也就是 strlcat），这样应该就能解决问题。否则，你可以尝试修补二进制文件的字符串表（前提是这不会违反代码签名，如果有的话）。你还可以用 -mmin-osx-version 10.7（甚至 10.6）重新编译，这样可能也能解决这个问题。
