我用code測試Boost程式,出現錯誤,想請前輩先進指導,謝謝.

• 程式:

#include <boost/lambda/lambda.hpp>
#include <iostream>
#include <iterator>
#include <algorithm>

int main()
{
    using namespace boost::lambda;
    typedef std::istream_iterator<int> in;

    std::for_each(
        in(std::cin), in(), std::cout << (_1 * 3) << " ");
}

• 錯誤訊息:

[Running] cd "d:\Desktop\c++\" && g++ boostexample.cpp -o demo && "d:\Desktop\c++\"demo
boostexample.cpp:1:35: fatal error: boost/lambda/lambda.hpp: No such file or directory
