| 8 | .SH DESCRIPTION
|
|---|
| 9 | The GNU build system distinguishes three types of machines, the
|
|---|
| 10 | `build' machine on which the compilers are run, the `host' machine
|
|---|
| 11 | on which the package being built will run, and, exclusively when you
|
|---|
| 12 | build a compiler, assembler etc., the `target' machine, for which the
|
|---|
| 13 | compiler being built will produce code.
|
|---|
| 14 |
|
|---|
| 15 | This script will guess the type of the `build' machine.
|
|---|
| 16 | .PP
|
|---|
| 17 | Output the configuration name of the system `config.guess' is run on.

| 28 | .SH "ENVIRONMENT VARIABLES"
|
|---|
| 29 | config.guess might need to compile and run C code, hence it needs a
|
|---|
| 30 | compiler for the `build' machine: use the environment variable
|
|---|
| 31 | `CC_FOR_BUILD' to specify the compiler for the build machine. If
|
|---|
| 32 | `CC_FOR_BUILD' is not specified, `CC' will be used. Be sure to
|
|---|
| 33 | specify `CC_FOR_BUILD' is `CC' is a cross-compiler to the `host'
|
|---|
| 34 | machine.
|
|---|
| 35 |
|
|---|
| 36 | CC_FOR_BUILD a native C compiler, defaults to `cc'
|
|---|
| 37 | CC a native C compiler, the previous variable is preferred
