config.guess

CONFIG.GUESS(1) 						   User Commands						   CONFIG.GUESS(1)

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
