The GCC Book is a comprehensive tutorial and guide to using the newest version of GCC, the "GNU Compiler Collection". GCC is quite simply the most used and most powerful tool for programmers on the planet. It goes beyond just command line invocations and teaches you how to use GCC to improve the quality of your code (with debugging, code profiling, and test code coverage) and how to integrate other GNU development tools, such as libtool, automake, and autoconf, into your GCC-based development projects.
