NAME

6       config.guess - guess the build system triplet
7

SYNOPSIS

9       config.guess [OPTION]
10

DESCRIPTION

12       The GNU build system distinguishes three types of machines, the `build'
13       machine on which the compilers are run, the `host' machine on which the
14       package  being  built  will run, and, exclusively when you build a com‐
15       piler, assembler etc., the `target' machine,  for  which  the  compiler
16       being built will produce code.
17
18       This script will guess the type of the `build' machine.
19
20       Output the configuration name of the system `config.guess' is run on.
21
22   Operation modes:
23       -h, --help
24              print this help, then exit
25
26       -t, --time-stamp
27              print date of last modification, then exit
28
29       -v, --version
30              print version number, then exit
31

ENVIRONMENT VARIABLES

33       config.guess  might  need  to  compile and run C code, hence it needs a
34       compiler  for  the  `build'  machine:  use  the  environment   variable
35       `CC_FOR_BUILD'  to  specify  the  compiler  for  the build machine.  If
36       `CC_FOR_BUILD' is not specified, `CC' will be used.  Be sure to specify
37       `CC_FOR_BUILD' is `CC' is a cross-compiler to the `host' machine.
38
39         CC_FOR_BUILD    a native C compiler, defaults to `cc'
40         CC               a  native  C compiler, the previous variable is pre‐
41       ferred
