Compile Error

[crimsonzero2]

I'm trying to compile my program, but I keep getting the error:

employee1.cc: In function ‘void Open()’:
employee1.cc:379:11: error: ‘stoi’ is not a member of ‘std’
employee1.cc:385:15: error: ‘stod’ is not a member of ‘std’
employee1.cc:387:12: error: ‘stoi’ is not a member of ‘std’

Here is the function that it is having issues with:

void Open()
{
	string rfile;
	string temp;
	
	cout << "Enter a file name to read from (be sure to add extension, \".txt\" to the end and use no spaces): ";
	cin >> rfile;
	
	if(fexists(rfile.c_str()))
	{
		ifstream infile;
		infile.open(rfile.c_str());
		
		while(true)
		{
			if(infile.eof())
			{
				break;
			}
			getline(infile, temp, ';');
			a.ID = std::stoi(temp);
			getline(infile, temp, ';');
			a.fname = temp;
			getline(infile, temp, ';');
			a.lname = temp;
			getline(infile, temp, ';');
			a.salary = std::stod(temp);
			getline(infile, temp, ';');
			a.hpw = std::stoi(temp);
			getline(infile, temp, '\n');
			a.work = temp;
			ListEmployee.push_back(a);
		}
		
		cout << "Data has been read." << endl;
		infile.close();
		return;
	}
	else
	{
		cout << "File does not exist.  No data read from any file." << endl;
	}
}

How do I fix the error? I'm using Cygwin as a compiler.

Why are you using std:: infront of those ones it names? std:: is for the cout,cin, etc.

Basically it is saying those are not members of std::

[MikeyBoy]

To the OP: Have you forgotten to include <string> ?

To topherpunch: I'm fairly sure stoi etc are members of std. They're declared in <string>

[crimsonzero2]

According to http://www.cplusplus.com/reference/string/stoi/?kw=stoi it's part of std and yes, I did include <string>.

-std=c++11

[MikeyBoy]

Ah - I hadn't spotted the little symbol on the ref page to indicate it's C++11 only.

[crimsonzero2]

I tried doing -std=c++11, can you explain to me where to put that part within the compiler?

[MikeyBoy]

First, you should check whether your compiler even has any C++11 support.

[crimsonzero2]

how would I check cygwin for that?

I tried looking it up with no luck

[MikeyBoy]

You wouldn't. Cygwin isn't a compiler. What is your compiler? gcc?

[crimsonzero2]

gcc/g++ yeah

[MikeyBoy]

Well then, check the man pages for it.

[crimsonzero2]

upon searching, I believe that I discovered that it does not have c++11 installed. In case if I can't get this installed, how would I do what I want in the above code without using stoi?

[MikeyBoy]

C++11 isn't a thing you install - it's a standard that either is or isn't supported by your particular version of g++. The man pages for it should tell you what you need to know. If not, check which version of gcc you have and look online.

[crimsonzero2]

what is the best method to do so I could get the code to work?

[MikeyBoy]

Well, if the version of g++ that you're using supports C++11 - and you haven't said yet whether or not that's true - then just using the compiler option ne555 suggests will work.

[crimsonzero2]

yeah, that method didn't really work. I end up getting the same error message
