construction const parameter問題 構造函數const引用參數問題

工程在window下編譯沒有任何問題, 可是在linux(CentOS6)下編譯就總是報錯

C++ 編譯器已升級到最新版 6.1.0

錯誤以下:

In file included from /usr/local/include/c++/6.1.0/bits/stl_algobase.h:64:0,
                 from /usr/local/include/c++/6.1.0/bits/char_traits.h:39,
                 from /usr/local/include/c++/6.1.0/string:40,
                 from CTIServer.h:5,
                 from CTIServer.cpp:2:

make: *** [CTIServer.o] 錯誤 1

　無論怎麼改都是報這個錯誤,

    感受過不去這個坎了~~~

錯誤源代碼就是在這一行,中間的不等於表達式:

for(pos=m_ExtUsrInfoList.begin();pos!=m_ExtUsrInfoList.end();pos++)

 

　而後 , 由於升級到C++11了嘛,改用 for:auto 方式循環,仍是同樣這一行報錯, 折騰的沒門 , 

因而懷疑C++11的問題?

因而 找了個 C++沒升級的試試,結果以下:

  看到後面

錯誤：對‘ExtUsrInfo::ExtUsrInfo(const ExtUsrInfo&)’的調用沒有匹配的函數
CTIServer.h:56: 附註：備選爲： ExtUsrInfo::ExtUsrInfo(ExtUsrInfo*) CTIServer.h:55: 附註： ExtUsrInfo::ExtUsrInfo(ExtUsrInfo&) CTIServer.h:54: 附註： ExtUsrInfo::ExtUsrInfo()

貌似終於發現了點什麼, 哈哈, 你妹的, 構造函數沒有 參數 是const類型的

const ExtUsrInfo&

!!!!

終於找到了,  可是還得感謝C++4.4.7 版本的 錯誤提示,  C++11 的錯誤 仍是難看懂!~

PS:  linux下的 編譯檢查 要比 window下 的(VS) 嚴格得多啊!~
