As Linux increases its presence throughout the world as a target platform for professional application development, its growth as a powerful, flexible system offering many free development tools assures its place in the future. By giving you easy access to this comprehensive range of tools, supporting new and nascent technologies, at little or no cost, developing with Linux allows you to apply the solution that's right for you.
In this follow-up to the best-selling Beginning Linux Programming, you will learn from the authors' real-world knowledge and experience of developing software for Linux; you'll be taken through the development of a sample 'DVD Store' application, with 'theme' chapters addressing different aspects of its implementation. Meanwhile, individual 'take-a-break' chapters cover important topics that go beyond the bounds of the central theme. All focus on the practical aspects of programming, showing how crucial it is to choose the right tools for the job, use them as they should be used, and get things right first time.
Who is this book for?
Experienced Linux programmers and aspiring developers alike will find a great deal of practical information in this book on libraries, techniques, tools and applications. You should be familiar with a simple Linux system, have a good working knowledge of programming in C, and a basic understanding of object-oriented programming with C++ for the Qt/KDE chapters.
What does this book cover?
Data storage in Linux - including coverage of PostgreSQL, MySQL and XML
Implementation of Linux GUIs - covering both KDE and GNOME
Web-based interfaces - using the PHP module for Apache
Python - including extending and embedding the language
Using RPC and CORBA to construct distributed object-based applications
Versioning (with CVS), documentation, internationalization and project distribution
Distributed hardware solutions such as diskless Linux and Beowulf clustering
By tapping the strengths of the open-source movement, developers can write custom Linux software without spending a dime on licensing fees. Aimed at the experienced C/C++ programmer,
Professional Linux Programming provides a wide-ranging and hands-on guide to the different pieces of the puzzle required to program successfully on this exciting new platform.
The book is framed as a case study for building a custom database program in Linux for a video-rental store. After a tour of the requirements and a brief look at project management for creating this software, the various Linux packages needed to implement this system are described, along with sample code, most of it written in C. Some packages (like the CVS version-control package) come with most distributions of Linux. Others will require downloading additional software over the Internet. In every case, you're provided with the actual command-line arguments needed to install, configure and run each package.
Besides a great exploration of CVS for version control, there's excellent coverage of the free PostgreSQL and MySQL databases, two very popular choices for Linux databases. The book also does a good job of explaining user-interface design under both the GTK+/GNOME and KDE (two popular Linux desktops) and how to extend the reach of the sample database application using Remote Procedure Calls (RPCs) and CORBA. Of course, the finished application doesn't use every Linux API covered here, but the book casts a wide net and introduces features and tools that are available.
Two standout chapters tour you through the essentials of other programming languages. There's PHP for Web development and an appealing, enthusiastic introduction to Python (which will probably turn you into a Python convert). Later chapters provide practical tips for testing and debugging applications, including how to profile your code. The book closes with a useful guide to creating Redhat Package Manager (RPM) packages for deploying applications, as well as a quick overview of your documentation options. By covering so many APIs, languages, and tools effectively, Professional L Linux Programming gives experienced C/C++ programmers all that they need to get started with Linux development. With its remarkably clear presentation style and abundance of practical tips, it's an admirably useful blueprint for building custom software. --Richard Dragan
