次のコードのコンパイルに問題があります。
#include <iostream>
#include <string>
#include <boost/regex.hpp>
using namespace std;
int main()
{
string s;
boost::regex re("^{(APPLE|ORANGE),(\\d*)}$");
boost::cmatch matches;
while(true)
{
cout << "String: ";
cin >> s;
if(boost::regex_match(s.c_str(), matches, re))
{
for(int i=1; i<matches.size(); i++)
{
string match(matches[i].first, matches[i].second);
cout << "match[" << i << "]: " << matches[i] << endl;
}
}
else
{
cout << "no match" << endl;
}
}
return 0;
}
次の行を使用して g++ でコンパイルしました。
g++ regexp_test.cpp -o regexp_test.o
も試しました:
g++ -lboost_regex regexp_test.cpp -o regexp_test.o
しかし、私はこの長いエラーが発生しています:

私は何を間違っていますか?
