The purpose of this book is to explain the use of the GNU C and C++
g++. After reading this book you
should understand how to compile a program, and how to use basic
compiler options for optimization and debugging. This book does not
attempt to teach the C or C++ languages themselves, since this material
can be found in many other places (see section Further reading).
Experienced programmers who are familiar with other systems, but new to
the GNU compilers, can skip the early sections of the chapters
"Compiling a C program", "Using the preprocessor" and
"Compiling a C++ program". The remaining sections and chapters
should provide a good overview of the features of GCC for those already
know how to use other compilers.
