Hi all,
        I have installed Boost 1.44 and I have a program from a tutorial I am trying to compile with out success.
The program is as follows:
===============================================================================
#include <iostream>
#include <vector>
#include <algorithm>
#include <boost/shared_ptr.hpp>

using namespace::std;

struct Boost_Example
{
  Boost_Example(int _x) : x (_x)
  {
  }
  ~Boost_Example()
  {
    std::cout << "Destroying Boost_Example x = " << x << "\n";
    std::cout << endl << endl << " ";
    system("PAUSE");
    cout << endl << endl;
  }
  int x;
};

typedef boost::shared_ptr<Boost_Example> Boost_ExamplePtr;

struct Boost_ExamplePtrOps
{
  bool operator()(const Boost_ExamplePtr &a, const Boost_ExamplePtr &b)
  {
    return a->x < b->x;
  }
  void operator()(const Boost_ExamplePtr &a)
  {
    std::cout << " " << a->x;
  }
};

int main()
{
  std::vector<Boost_ExamplePtr> Boost_Example_Vector;

  Boost_Example_Vector.push_back(Boost_ExamplePtr(new Boost_Example(3)));
  Boost_Example_Vector.push_back(Boost_ExamplePtr(new Boost_Example(2)));
  Boost_Example_Vector.push_back(Boost_ExamplePtr(new Boost_Example(1)));
  //
  std::cout << endl << endl;
  std::cout << " Original Boost_Example_Vector" ;
  std::for_each(Boost_Example_Vector.begin(), Boost_Example_Vector.end(), Boost_ExamplePtrOps());
  std::cout << "\n";
  //
  std::sort(Boost_Example_Vector.begin(), Boost_Example_Vector.end(), Boost_ExamplePtrOps());
  std::cout << endl << endl;
  std::cout << "Sorted Boost_Example_vector:  " ;
  std::for_each(Boost_Example_Vector.begin(), Boost_Example_Vector.end(), Boost_ExamplePtrOps());
  std::cout << " \n";
  //
  std::cout << endl << endl << " " ;
  system("PAUSE");
  std::cout << endl << endl;
  //
  return 0;
}
=============================================================================
Just create an empty VC++ project and add a source file to it. Then paste this code in the source file.
I believe that, if Boost is correctly installed on one's machine, this should compile correctly. For additional information, I have set up the include and lib directories as under:
includes:
$(BOOST_ROOT)boost
libs
$(BOOST_ROOT)stage\lib
$(BOOST_ROOT)libs
$(BOOST_ROOT)bin.v2
In the above paths, $(BOOST_ROOT) is added to "System Variables" under the "Environment Variables" as C:\Program Files\boost\boost_1_44_0 where it is installed. Shall a "\" be added in the end? Or shall this variable be added to "Path variables" instead of "System variables"?
I believe that my environment is rightly setup. But I am still having problems building a simple console application. I am using Visual Studio 2008 on Windows 7.
Please let me know, what to do and where to check for the missing block?
Thanks and regards,
Bhushan
