Try:
using namespace boost::lambda;

You forgot a semicolon:
int a[10];

If it doesn't compile with this, please copy the error text so we can help you.

OTOH, this complete example works for me:

---- Start code  ----
#include <boost/lambda/lambda.hpp>
#include <iostream>

int main()
{
    using namespace boost::lambda;

    int a[10];
    std::for_each(a, a+10, std::cout  << _1);
}
---- End code  ----
