Linux đã luôn luôn cung cấp một môi trường lập trình phong phú, và nó chỉ phát triển phong phú hơn. Hai trình biên dịch mới, EGCS và pgcs, tham gia dự án GNU gcc, trình biên dịch Linux gốc. Trong thực tế, như cuốn sách này đã cho báo chí, Quỹ phần mềm miễn phí, chăm sóc của dự án GNU, thông báo rằng gcc sẽ được duy trì | Introduction Linux has always provided a rich programming environment and it has only grown richer. Two new compilers egcs and pgcs joined the GNU project s gcc the original Linux compiler. In fact as this book went to press the Free Software Foundation custodians of the GNU project announced that gcc would be maintained by the creators and maintainers of egcs. A huge variety of editors stand alongside the spartan and much-maligned vi and emacs marvelous complexity. Driven largely by the Linux kernel GNU s C library has evolved so dramatically that a new version glibc also known as libc6 has emerged as the standard C library. Linux hackers have honed the GNU project s always serviceable development suite into powerful tools. New widget sets have taken their place beside the old UNIX standbys. Lesstif is a free source-compatible implementation of Motif KDE the K Desktop Environment based on the Qt class libraries from TrollTech answers the desktop challenge posed by the X Consortium s CDE Common Desktop Environment . What This Book Will Do for You In this book we propose to show you how to program in on and for Linux. We ll focus almost exclusively on the C language because C is still Linux s lingua franca. After introducing you to some essential development tools we dive right in to system programming followed by a section on interprocess communication and network programming. After a section devoted to programming Linux s user interface with both text-based and graphical tools the X Window system a section on specialized topics including shell programming security considerations and using the GNU project s gdb debugger rounds out the technical discussion. We close the book with three chapters on a topic normally disregarded in programming books delivering your application to users. These final chapters show you how to use package management tools such as RPM how to create useful documentation and discuss licensing issues and options. If we ve done our job .
