On x86_64 Linux, a C compiler producing 32bit code causes the guessed CPU to be changed to i686. Adapt this approach for aarch64 Linux, i.e. change the guessed CPU to armv8l when a compiler producing arm eabi code is detected. * config.guess (aarch64:Linux:*:*): Test for the 32-bit ABI. * doc/config.guess.1: Regenerate.

.SH NAME
|
|
config.guess \- guess the build system triplet
|
|
.SH SYNOPSIS
|
|
.B config.guess
|
|
[\fI\,OPTION\/\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.

\fB\-v\fR, \fB\-\-version\fR
|
|
print version number, then exit
|
|
.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' if `CC' is a cross-compiler to the `host'
|
|
machine.
|
|
|
|
CC_FOR_BUILD a native C compiler, defaults to `cc'
|
|
CC a native C compiler, CC_FOR_BUILD is preferred
|
|
.SH "REPORTING BUGS"
