工程在window下编译没有任何问题, 但是在linux(CentOS6)下编译就老是报错
C++ 编译器已升级到最新版 6.1.0
错误如下:
In file included from /usr/local/include/c++/6.1./bits/stl_algobase.h::,

make: *** [CTIServer.o] 错误
不管怎么改都是报这个错误,
感觉过不去这个坎了~~~
错误源代码就是在这一行,中间的不等于表达式:
for(pos=m_ExtUsrInfoList.begin();pos!=m_ExtUsrInfoList.end();pos++)
然后 , 因为升级到C++11了嘛,改用 for:auto 方式循环,还是一样这一行报错, 折腾的没门 ,
于是怀疑C++11的问题?
于是 找了个 C++没升级的试试,结果如下:

看到后面

CTIServer.h:55: 附注： ExtUsrInfo::ExtUsrInfo(ExtUsrInfo&)
CTIServer.h:54: 附注： ExtUsrInfo::ExtUsrInfo() 貌似终于发现了点什么, 哈哈, 你妹的, 构造函数没有 参数 是const类型的
const ExtUsrInfo&
!!!!
终于找到了, 但是还得感谢C++4.4.7 版本的 错误提示, C++11 的错误 还是难看懂!~
PS: linux下的 编译检查 要比 window下 的(VS) 严格得多啊!~
