NAME

   config.guess - guess the build system triplet

SYNOPSIS

   config.guess [OPTION]

DESCRIPTION

   The GNU build system distinguishes three types of machines, the `build'
   machine on which the compilers are run, the `host' machine on which the
   package  being  built  will  run,  and,  exclusively  when  you build a
   compiler, assembler etc., the `target' machine, for which the  compiler
   being built will produce code.

   This script will guess the type of the `build' machine.

   Output the configuration name of the system `config.guess' is run on.

   Operation modes:
   -h, --help
          print this help, then exit

   -t, --time-stamp
          print date of last modification, then exit

   -v, --version
          print version number, then exit

ENVIRONMENT VARIABLES

   config.guess  might  need  to  compile and run C code, hence it needs a
   compiler  for  the  `build'  machine:  use  the  environment   variable
   `CC_FOR_BUILD'  to  specify  the  compiler  for  the build machine.  If
   `CC_FOR_BUILD' is not specified, `CC' will be used.  Be sure to specify
   `CC_FOR_BUILD' is `CC' is a cross-compiler to the `host' machine.

     CC_FOR_BUILD    a native C compiler, defaults to `cc'
     CC               a  native  C  compiler,  the  previous  variable  is
   preferred

Opportunity


Personal Opportunity - Free software gives you access to billions of dollars of software at no cost. Use this software for your business, personal use or to develop a profitable skill. Access to source code provides access to a level of capabilities/information that companies protect though copyrights. Open source is a core component of the Internet and it is available to you. Leverage the billions of dollars in resources and capabilities to build a career, establish a business or change the world. The potential is endless for those who understand the opportunity.

Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.



Free Software


Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.

Free Office Software - The Libre Office suite provides top desktop productivity tools for free. This includes, a word processor, spreadsheet, presentation engine, drawing and flowcharting, database and math applications. Libre Office is available for Linux or Windows.



Free Books


The Free Books Library is a collection of thousands of the most popular public domain books in an online readable format. The collection includes great classical literature and more recent works where the U.S. copyright has expired. These books are yours to read and use without restrictions.

Source Code - Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.



Education


Study at Harvard, Stanford or MIT - Open edX provides free online courses from Harvard, MIT, Columbia, UC Berkeley and other top Universities. Hundreds of courses for almost all major subjects and course levels. Open edx also offers some paid courses and selected certifications.

Linux Manual Pages - A man or manual page is a form of software documentation found on Linux/Unix operating systems. Topics covered include computer programs (including library and system calls), formal standards and conventions, and even abstract concepts.
