The only valid syntax to declare a const reference to an std::string is 'std::string const & first' or 'const std::string & first'. Putting the const qualifier elsewhere is an error.
Get a C++ book, teach yourself and stop spamming this list. Your questions are not only too basic but also off-topic. That is a warning. I am not willing to be unhelpful but at the moment the only thing helpful (to this list) is telling you to STFU. If you don't, someone would have to make it happen by force. ------------------ Best regards, lh_mouse 2016-07-17 ------------------------------------------------------------- 发件人：Jim Michaels <[email protected]> 发送日期：2016-07-17 01:46 收件人：mingw64 users 抄送： 主题：[Mingw-w64-public] g++ throwing compiler out with the bathwater build 0708 (internally 0609) #include <stdio.h> #include <string> #include <vector> namespace str { //string type for S like std::string, std::wstring, etc. int compare(std::string& first const, std::string& second const, bool iCase=false, size_t firstPos=0) const { ... } I had thought the problem might be the & reference, so I dropped those and same error message. g++ seems to now be throwing errors on any syntax. it must be royally confused. and it still doesn't like ) on functions.
