Provides a complete command reference and explains how to use the info online help system Covers material not covered in other texts: profiling, test coverage, and how to build and install GCC on a variety of operating system and hardware platforms Explains how to build and install GCC on Linux, UNIX, and Windows systems, whether you have an existing GCC or not The GCC Book is a comprehensive tutorial and guide to using the newest version of GCC, the "Gnue 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. The GCC Book teaches you how to build, install, customize, use, and troubleshoot GCC 3.2, the GNU Compiler Collection version 3.2. GCC has long been available for most major hardware and operating system platforms and is often the preferred compiler for those platforms. As a general purpose compiler, GCC produces higher quality, faster performing executable code with fewer bugs than equivalent offerings supplied by hardware and software vendors. GCC, along with GNU Emacs, the Linux operating system, the Apache Web server, the Sendmail mail server, and the BIND DNS server, is one of the showpieces of the free software world and proof that sometimes you can get a free lunch.
