Compilation fails at "line.insert(line.end(), x.begin(), i);" and I
can't figure out why. Here is the code:

/*
	5-1. Design and implement a program to produce a permuted index. A
permuted
	index is one in which each phrase is indexed by every word in the
phrase.
*/

#include <cctype>
#include <iostream>
#include <string>
#include <list>

using std::cin;
using std::cout;
using std::isspace;
using std::string;
using std::list;

int main() {
	string x;
	list<list<string> > indexes;
	while (getline(cin, x)) {
		string::const_iterator i =3D x.begin();
		list<string> line;
		while (i < x.end()) {
			while (i < x.end() && isspace(*i)) x.erase(*(i++));
			while (i < x.end() && !isspace(*i)) ++i;
			line.insert(line.end(), x.begin(), i);
		}
		indexes.push_back(line);
	}

Your 'line' is a list of strings.  Your 'x.begin()' is an iterator in a 
string.  If you intended to insert the entire 'x' string into your list 
of strings (append), then you probably wanted to do

    line.insert(line.end(), x);

If not, describe to us *what it is you're trying to accomplish*.

I want to insert the contents of 'x' from its start through 'i' into
'line'.

See 'substr' member of 'string'.
