.SH NAME

config.guess \- guess the build system triplet

.SH SYNOPSIS

.B config.guess

[\fIOPTION\fR]

.SH 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.

.PP

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

.SH "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
