Using Boost on ubuntu

Question

I\'ve heard a lot of good comments about Boost in the past and thought I would give it a try. So I downloaded all the required packages from the package manager in Ubuntu 9.

Answer 1

Agreed; the boost website has good tutorials for the most part, broken down by sub-library.

As for compiling, a good 80% of the library implementation is defined in the header files, making compiling trivial. for example, if you wanted to use shared_ptr's, you'd just add

#include <boost/shared_ptr.hpp>

and compile as you normally would. No need to add library paths to your g++ command, or specify -llibboost. As long as the boost directory is in your include path, you're all set.

From the boost documentation:

The only libraries that need to be compiled and linked are the following:The only Boost libraries that must be built separately are:

• Boost.Filesystem
• Boost.IOStreams
• Boost.ProgramOptions
• Boost.Python (see the Boost.Python build documentation before building and installing it)
• Boost.Regex
• Boost.Serialization
• Boost.Signals
• Boost.Thread
• Boost.Wave

A few libraries have optional separately-compiled binaries:

• Boost.DateTime has a binary component that is only needed if you're using its to_string/from_string or serialization features, or if you're targeting Visual C++ 6.x or Borland.
• Boost.Graph also has a binary component that is only needed if you intend to parse GraphViz files.
• Boost.Test can be used in “header-only” or “separately compiled” mode, although separate compilation is recommended for serious use.

So, if you're using one of the listed libraries, use the Getting Started guide to, well, get you started on compiling and linking to Boost.

Answer 2

Boost is not a programming language nor an application framework - because it's just a collection of libraries, there is no such thing as a Boost 'Hello World' program. Most libraries in Boost can be used more or less independently, and they vary in size from one function to massive libraries that could stand alone.

The best way to get to know Boost is simply to try and work it in as you write new code. Use smart_ptr whenever you can; use the MPL next time you want to do compile-time work. There's a lot of variety in Boost, but you should probably start looking at the Utility section; those are the lightest-weight and most commonly-used libraries.
