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.

OPTIONS

-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
