先說解決方法：

因為我出現這個比較奇特，我再下面環境中的第一個項目有這個問題，但是不知道怎麽瞎折騰就搞定了，不報這個異常了

不論是Qt Creator直接運行Debug或者Release都沒問題

但是我後續建立的項目始終有這個問題，經過幾天的折騰發現新項目如果使用sudo命令啟動程序就不會報異常，所以目前我的Qt Creator也用sudo命令啟動。

下面的方法我都沒有嘗試過，但是應該最貼近根本原因的。

至於為什麽同一個Qt Creator創建並打開的第一個項目正常，但是後續的就異常，目前還不清楚，後續調查清楚了再來更新。

先介紹一下環境：

Ubuntu 16.04

Qt 5.10

Caffe封裝的人臉檢測庫

錯誤原因：

Caffe中用到的libprotobuf版本與Qt中引用的版本沖突

具體異常如下：

Debugging starts
