Introduction </H1><!--docid::SEC1::--><P>Autoconf, Automake and Libtool are packages for making your softwaremore portable and to simplify building it--usually on someone else'ssystem. Software portability and effective build systems are crucialaspects of modern software engineering practice. It is unlikely that asoftware project would be started today with the expectation that thesoftware would run on only one platform. Hardware constraints maychange the choice of platform, new customers with different kinds ofsystems may emerge or your vendor might introduce incompatible changesin newer versions of their operating system. In addition, tools thatmake building software easier and less error prone are valuable.</P><P>Autoconf is a tool that makes your packages more portable by performingtests to discover system characteristics before the package is compiled.Your source code can then adapt to these differences.</P><P>Automake is a tool for generating <TT>`Makefile'</TT>s--descriptions ofwhat to build--that conform to a number of standards. Automakesubstantially simplifies the process of describing the organization of apackage and performs additional functions such as dependency trackingbetween source files.</P><P>Libtool is a command line interface to the compiler and linker thatmakes it easy to portably generate static and shared libraries,regardless of the platform it is running on.</P><P><A NAME="What this book is"></A></TR></TABLE><BR> <FONT SIZE="-1">This document was generatedby <I>Gary V.
