C++ 编译报错记录

1. error: default argument given for parameter 3 of ‘void split(const string&, std::vector >&, char)’ [-fpermissive]
 void split(const std::string &s, std::vector &sv, const char flag = ' ')

/home/zhouying/lcl/test/FotaService/include/util.h:6:6: note: previous specification in ‘void split(const string&, std::vector >&, char)’ here
 void split(const std::string &s, std::vector &sv, const char flag = ' ');

原因：头文件util.h中第三个形参设置了默认值，util.cpp 中函数定义时第三个形参设置了默认值导致保存，删除util.cpp 中函数定义时第三个形参默认值
