<h4 class="subsubsection">6.3.2.1 Scripts Used by <samp>configure</samp></h4>
|
||
|
|
|
||
|
|
<p><samp>configure</samp> uses some other scripts to help in its work:
|
||
|
|
</p>
|
||
|
|
<ul>
|
||
|
|
<li> The standard GNU <samp>config.sub</samp> and <samp>config.guess</samp>
|
||
|
|
files, kept in the top level directory, are used.
|
||
|
|
|
||
|
|
</li><li> The file <samp>config.gcc</samp> is used to handle configuration
|
||
|
|
specific to the particular target machine. The file
|
||
|
|
<samp>config.build</samp> is used to handle configuration specific to the
|
||
|
|
particular build machine. The file <samp>config.host</samp> is used to handle
|
||
|
|
configuration specific to the particular host machine. (In general,
|
||
|
|
these should only be used for features that cannot reasonably be tested in
|
||
|
|
Autoconf feature tests.)
|
||
|
|
See <a href="System-Config.html#System-Config">The <samp>config.build</samp>; <samp>config.host</samp>;
|
||
|
|
and <samp>config.gcc</samp> Files</a>, for details of the contents of these files.
|
||
|
|
|
||
|
|
</li><li> Each language subdirectory has a file
|
||
|
|
<samp><var>language</var>/config-lang.in</samp> that is used for
|
||
|
|
front-end-specific configuration. See <a href="Front-End-Config.html#Front-End-Config">The Front
|
||
|
|
End <samp>config-lang.in</samp> File</a>, for details of this file.
|
||
|
|
|
||
|
|
</li><li> A helper script <samp>configure.frag</samp> is used as part of
|
||
|
|
creating the output of <samp>configure</samp>.
|
||
|
|
</li></ul>
