Opis Linux Programmer's Toolbox: Kernighan and Ritchie show readers how to program the standard C libraries. Stevens covers the network programming interfaces in UNIX. But neither covers the tools developers need to master to be productive in Linux: compilers, debuggers, source code control, packaging etc... This book is the professional developer's guide to these tools. Linux as a software development platform is rich in tools - hundreds of tools, with new ones being developed all the time. Experienced C and C++ developers moving to Linux for the first time need to understand which tools are the best, and how to use them. This book is their guide. The book begins with a discussion of how to install, patch, and manage software development tools on a linux system. It then proceeds to cover editors, source code control tools, code beautifiers, IDEs, and revision control tools. The next two sections deal with configuring a build environment and working with documentation tools including texinfo, docbook, modinfo, and others. The book ends with a chapter on popular debugging tools and techniques, and another on the powerful but often bewildering performance tools available on Linux systems. The book is in the Arnold Robbins Linux Programming by Example Series. As is true of all books in this series, the book will use real program code from working programs to illustrate all key concepts. Master the Linux Tools That Will Make You a More Productive, Effective Programmer The Linux Programmer's Toolbox helps you tap into the vast collection of open source tools available for GNU/Linux. Author John Fusco systematically describes the most useful tools available on most GNU/Linux distributions using concise examples that you can easily modify to meet your needs. You'll start by learning the basics of downloading, building, and installing open source projects. You'll then learn how open source tools are distributed, and what to look for to avoid wasting time on projects that aren't ready for you. Next, you'll learn the ins and outs of building your own projects. Fusco also demonstrates what to look for in a text editor, and may even show you a few new tricks in your favorite text editor. You'll enhance your knowledge of the Linux kernel by learning how it interacts with your software. Fusco walks you through the fundamentals of the Linux kernel with simple, thought-provoking examples that illustrate the principles behind the operating system. Then he shows you how to put this knowledge to use with more advanced tools. He focuses on how to interpret output from tools like sar, vmstat, valgrind, strace, and apply it to your application; how to take advantage of various programming APIs to develop your own tools; and how to write code that monitors itself. Next, Fusco covers tools that help you enhance the performance of your software. He explains the principles behind today's multicore CPUs and demonstrates how to squeeze the most performance from these systems. Finally, you'll learn tools and techniques to debug your code under any circumstances. Coverage includes
