ABOUT THIS BOOK xxi Software requirements To use the code from this book unchanged,you'll need a recent C++compiler that supports the new C++11 language features used in the examples(see appendix A), and you'll need a copy of the C++Standard Thread Library. At the time of writing,g++is the only compiler I'm aware of that ships with an implementation of the Standard Thread Library,although the Microsoft Visual Studio 2011 preview also includes an implementation.The g++implementation of the Thread Library was first introduced in a basic form in g++4.3 and extended in subse- quent releases.g++4.3 also introduced the first support for some of the new C++11 language features;more of the new language features are supported in each subse- quent release.See the g++C++11 status page for details. Microsoft Visual Studio 2010 provides some of the new C++11 language features, such as rvalue references and lambda functions,but doesn't ship with an implementa- tion of the Thread Library. My company,Just Software Solutions Ltd,sells a complete implementation of the C++11 Standard Thread Library for Microsoft Visual Studio 2005,Microsoft Visual Studio 2008,Microsoft Visual Studio 2010,and various versions of g++.?This imple- mentation has been used for testing the examples in this book. The Boost Thread Library provides an API that's based on the C++11 Standard Thread Library proposals and is portable to many platforms.Most of the examples from the book can be modified to work with the Boost Thread Library by judicious replacement of std:with boost:and use of the appropriate #include directives. There are a few facilities that are either not supported (such as std:async)or have different names(such as boost:unique future)in the Boost Thread Library.
