 > Use BOOST_AUTO instead (see here: http://boost-spirit.com/home/articles

 /qi-example/zero-to-60-mph-in-2-seconds/). The article explains the
 rationale as well.

 Excuse me! I've changed 'auto' to 'BOOST_AUTO', but it doesn't work! I got
 the same error as before. In addition, I used gcc4.6.3 which supports
 'auto' keyword. Would you have any idea?

 Code:
 #include<boost/spirit/include/karma.hpp>
 #include<boost/spirit/include/karma_format_attr.hpp>
 #include<list>
 #include<iostream>

 BOOST_AUTO(par, '{' << -(boost::spirit::karma::int_ % ',') <<
 '}');//Define par here would lead to error!
 int main(){
         using namespace std;
         namespace karma = boost::spirit::karma;
         list<int> l{1, 2, 4};
         //BOOST_AUTO(par, '{' << -(boost::spirit::karma::int_ % ',') <<
 '}');//Whils this would not!
         cout<<karma::format(par, l)<<endl;
         return 0;
 }
