<h4 class="subsubsection">6.3.2.2 The <samp>config.build</samp>; <samp>config.host</samp>; and <samp>config.gcc</samp> Files</h4>
|
|
|
|
<p>The <samp>config.build</samp> file contains specific rules for particular systems
|
|
which GCC is built on. This should be used as rarely as possible, as the
|
|
behavior of the build system can always be detected by autoconf.
|
|
</p>
|
|
<p>The <samp>config.host</samp> file contains specific rules for particular systems
|
|
which GCC will run on. This is rarely needed.
|
|
</p>
|
|
<p>The <samp>config.gcc</samp> file contains specific rules for particular systems
|
|
which GCC will generate code for. This is usually needed.
|
|
</p>
|
|
<p>Each file has a list of the shell variables it sets, with descriptions, at the
|
|
top of the file.
|
|
</p>
|
|
<p>FIXME: document the contents of these files, and what variables should
|
|
be set to control build, host and target configuration.
