BOOST C++ LIBRARIES TUTORIAL
YOU WILL LEARN HOW TO:
1. DOWNLOAD THE BOOST C++ LIBRARIES.
2. INSTALL THE BOOST C++ LIBRARIES ON MICROSOFT WINDOWS VISUAL STUDIO 2008.
• I. INTRODUCTION
Hello; nice to meet you! Welcome to the, “BOOST C++ LIBRARIES TUTORIAL.”
C++0x is the working name for the next version of the C++ Standard. Technical Report 1 (TR1) and TR2 describe proposed changes to the C++ Standard. The TR1 and TR2 proposed changes include changes to the C++ Standard Template Library (STL); for example, adding some of the Boost C++ Libraries.
The existing C++ STL has provided tested solutions to common programming problems, shortened development cycles, and improved program quality. The Boost C++ Libraries are free open source libraries that are expected to continue the standard of excellence established by the STL.
This tutorial will cover downloading and installing Boost C++ Libraries on Microsoft Windows Visual Studio 2008.
• II. DOWNLOADING BOOST C++ LIBRARIES
There are many excellent Boost C++ Libraries free download websites to choose from, including the following:
http://www.boost.org/
The Boost C++ Libraries are constantly being updated with new additions. I have been using Boost C++ Libraries for a long time, my current download is:
C:\Program Files\boost\boost_1_35_0
It is a large download; however, follow the directions and respond when prompted and the download should not be a problem.
• III. INSTALLING BOOST C++ LIBRARIES
After you have successfully completed the download, the following steps can be used to install the Boost C++ Libraries on Microsoft Windows Visual Studio 2008:
1. From Visual Studio's File menu, select New > Project.
2. In the left-hand pane of the resulting New Project dialog, select Visual C++ >Win32.
3. In the right-hand pane, select Win32 Console Application Win32 Console Project.
4. In the name field, enter “boost”.
5. Right-click example in the Solution Explorer pane and select Properties from the resulting pop-up menu.
6. In Configuration Properties > C/C++ > General > Additional Include Directories, enter the path to the Boost root directory, for example:
C:\Program Files\boost\boost_1_35_0
7. In Configuration Properties > C/C++ > Precompiled Headers, change Use Precompiled Header to Not Using Precompiled Headers.
8. Replace the contents of the boost.cpp generated by the IDE with the example code below:
#include <vector>
#include <iostream>
#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");
std::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;
}
9. From the Build menu, select Build Solution.
When you have a successful build you should get the following message:
========== Rebuild All: 1 succeeded, 0 failed, 0 skipped ==========
10. From the Debug menu, select Start Debugging.
The output should be as follows:
Original Boost_Example _vector: 3 2 1 Sorted Boost_Example _vector: 1 2 3 Destroying Boost_Example x = 1 Destroying Boost_Example x = 2 Destroying Boost_Example x = 3
If you have any problems please post your questions on the DIC forum.
