可能因為 Backdoor.MAC.Eleanor 的出現，Apple 取消了System Preferences > Security & Privacy 中 Gatekeeper 允許執行任何來源應用程式，但是 Gatekeep 是可以用 terminal 來關閉，達到容許執行任何來源應用程式(也包括病毒)，請小心使用。

打開　Terminal
輸入　sudo spctl --master-disable


回復 Gatekeeper 功能：
打開　Terminal
輸入　sudo spctl --master-enable

 To check whether Mail.app is allowed to run on the local system:

export LDFLAGS="-stdlib=libc++"

link to libc++ or libstdc++

the stl function symbol in object file are different in mac with xcode 7

when use std::vector as a argument

the argument symbol is St6vectorIiSaIi linking to libstdc++

the other is St3__16vectorIiNS6_9allocatorIi

this will cause linking errors
