In the recent years, Linux, a public domain, freely available Unix variant has attracted the people very much. Today's complex production environments demands superior application performance. Linux is having extraordinary advantages such as: complete source code access, availability of exceptional optimization, testing tools. This book is to explore this facet of Linux.
Features
- Explained Linux success stories with emphasis on facilities and tools available in Linux for SW development
- Explains gcc (GNU) toolchain in detail, combining C and C++, C and Java, and C and Fortran in a lucid manner
- How command line arguments can be handled by C/C++ programs with getopt, argp library are dealt
- Discusses about environment variables and their management
- System limits are explored with their implication of program performance
- Explains about how assembly programming can be done under Linux
- How to mix C and assembly, how system calls can be called from assembly, how modules can be developed in assembly and a bare boot (OS) program creation, are discussed in detail.
- How static and dynamic libraries are
- A popularly used tool for detecting memory errors, Electric Fence, is explained with concept oriented examples
- A chapter on Valgrind explained as to how memory can be checked for memory leaks, segment violations, analyze the cache performance in an illustrative manner
- Describes memory mapping of files, especially for large files and the impact on program's performance.
- Gnu debugger (gdb) is detailed; gcov and gprof explains about profiling of a C program to improve its performance; make, rcs, SW tools explains how they can be used for SW development in practice.with concept oriented examples with special reference to Web enabled applications.
- developed and commissioned in Linux is explained and how Libtool can be used for library development is discussed
- Dealt with Lex/Yacc tools, which are to be used in compiler development
- Memory management, memory errors, Linux memory management, etc., are described with illustrative examples
