Hi,

I'm a newbie with mpl and I'm trying to execute some example code from
the book "C++ Template Metaprogramming", by Abrahams and Gurtovoy:
>From section 5.2, p. 78, Sequences and Algorithms:

I wrote this code:
// 
// mpltest.C
// 
#include<boost/mpl/vector.hpp>

using namespace boost;

typedef mpl::vector<char,short,int,long,float,double> types;

typedef mpl::find<types,long>::type long_pos;

int main()
{
}

And I get this compiler error on the mpl::find line:
$ g++ mpltest.C -ompltest
mpltest.C:10: error: expected initializer before ‘<’ token

Can you tell me what I'm doing wrong?

Thank you,
Mike
