	<LI>GNU Software Currently Available



</UL>







<P>The GNU project, administered by the Free Software Foundation (FSF), seeks to



provide software (in the form of source code) that is freely available to anyone



who wants to use it. The project has a lengthy manifesto that explains the motivation



behind this libertarian undertaking (for which we should all be thankful, since GNU



has some of the best software around!). One of the key ideas within this manifesto



is that high-quality software is an intrinsic human right, just as the air that we



breathe is. Although GNU software is freely distributed, it is not public domain



and is protected by the GNU General Public License. The main purpose behind the license



is to keep GNU software free.</P>



<P>For more information on the FSF, you can write to them at <BR>

<P>The distribution of Linux on this book's CD-ROM comes with virtually all of the



GNU programs that are currently available. They are archived using the <TT>tar</TT>



program and compressed using the GNU <TT>gzip</TT> utility. <TT>gzip</TT> tends to



compress better than the standard UNIX compression utility, <TT>compress</TT>. Files



compressed with <TT>gzip</TT> end with a <TT>.gz</TT> suffix, whereas <TT>compress</TT>



files end in <TT>.Z</TT>. However, <TT>gzip</TT> can uncompress <TT>compress</TT>



files as well as its own.</P>



<P>Each of these compressed files has a version number included in its filename so



that you can determine what version is most current. Once you decompress and un-<TT>tar</TT>



the GNU file, the program can be compiled and installed on your system. Most of the



files come with their own makefile. Most of the programs are refinements of standard



Linux utilities such as <TT>make</TT> and <TT>bc</TT>.



<H3 ALIGN="CENTER"><A NAME="Heading3<FONT COLOR="#000077">GNU Software Currently



Available</FONT></H3>



<P>So much software, either developed by or made available through the Free Software



Foundation (which develops the GNU products), is available that each program cannot



be described in detail. The following sections have brief descriptions of the GNU



utilities and programs that are included with this distribution of Linux. They are



summaries based on the descriptions of the programs as supplied by GNU.



<H4 ALIGN="CENTER"><A NAME="Heading4<FONT COLOR="#000077">autoconf</FONT></H4>



<P><TT>autoconf</TT> generates shell scripts that can automatically configure source



code packages (such as those for GNU). <TT>autoconf</TT> creates a script for a software



package from a file which lists the operating system features that the package can



utilize. <TT>autoconf</TT> requires GNU <TT>m4</TT> to generate the required macro



calls for its operation.



<H4 ALIGN="CENTER"><A NAME="Heading5<FONT COLOR="#000077">bash</FONT></H4>



<P>The shell called <TT>bash</TT> is an enhancement of the Bourne shell (thus the



name, which stands for Bourne Again SHell). It offers many of the extensions found



in <TT>csh</TT> and <TT>ksh</TT>. The <TT>bash</TT> shell also has job control, <TT>csh</TT>-style



command history, and command-line editing with <TT>Emacs</TT> and <TT>vi</TT> modes



built in. See Chapter 10, &quot;<TT>bash</TT>.&quot;



<H4 ALIGN="CENTER"><A NAME="Heading6<FONT COLOR="#000077">bc</FONT></H4>



<P><TT>bc</TT> is an algebraic language that can be used interactively from a shell



command line, or with input files. GNU <TT>bc</TT> has a C-like syntax with several



extensions including multicharacter variable names, an <TT>else</TT> statement, and



full Boolean expressions. Unlike standard <TT>bc</TT>, GNU <TT>bc</TT> does not require



the separate <TT>dc</TT> program, which is another GNU calculator utility.



<H4 ALIGN="CENTER"><A NAME="Heading7<FONT COLOR="#000077">BFD</FONT></H4>



<P>The BFD library allows a program that operates on object files (such as <TT>ld</TT>



or <TT>gdb</TT>) to support many different formats efficiently. BFD provides a portable



interface, so that only BFD needs to know the details of a particular format. One



result is that all programs using BFD will support formats such as <TT>a.out</TT>



(default C executable) and <TT>COFF</TT>.



<H4 ALIGN="CENTER"><A NAME="Heading8<FONT COLOR="#000077">binutils</FONT></H4>



<P><TT>binutils</TT> includes a collection of development programs, including <TT>ar</TT>,



<TT>as</TT>,<TT> c++filt</TT>, <TT>gasp</TT>,<TT> gprof</TT>, <TT>encaps</TT>,<TT>



ld</TT>, <TT>nm</TT>,<TT> objcopy</TT>, <TT>objdump</TT>, <TT>ranlib</TT>, <TT>strings</TT>,



<TT>strings-gnu</TT>, <TT>strip</TT>, <TT>ld86</TT>, and <TT>as86</TT>.</P>



<P><TT>binutils</TT> Version 2.6.0.14 is written to use the BFD library. The GNU



linker <TT>ld</TT> emits source-line numbered error messages for multiply-defined



symbols and undefined references. The <TT>objdump</TT> program can display data such



as symbols from any file format understood by BFD.



<H4 ALIGN="CENTER"><A NAME="Heading9<FONT COLOR="#000077">bison</FONT></H4>



<P><TT>bison</TT> is an upwardly compatible replacement for the parser generator



<TT>yacc</TT>. <TT>bison</TT> takes a description of tokens in the form of a grammar



and generates a parser in the form of a C program.
