<h3 class="section">C.2 Invoking the <small>GDB</small> <samp>configure</samp> Script</h3>
|
||
|
|
<a name="index-configuring-GDB"></a>
|
||
|
|
<p><small>GDB</small> comes with a <samp>configure</samp> script that automates the process
|
||
|
|
of preparing <small>GDB</small> for installation; you can then use <code>make</code> to
|
||
|
|
build the <code>gdb</code> program.
|
||
|
|
</p>
|
||
|
|
<p>The <small>GDB</small> distribution includes all the source code you need for
|
||
|
|
<small>GDB</small> in a single directory, whose name is usually composed by
|
||
|
|
appending the version number to ‘<samp>gdb</samp>’.
|
||
|
|
</p>
|
||
|
|
<p>For example, the <small>GDB</small> version 8.3 distribution is in the
|
||
|
|
<samp>gdb-8.3</samp> directory. That directory contains:
|
||
|
|
</p>
|
||
|
|
<dl compact="compact">
|
||
|
|
<dt><code>gdb-8.3/configure <span class="roman">(and supporting files)</span></code></dt>
|
||
|
|
<dd><p>script for configuring <small>GDB</small> and all its supporting libraries
|
||
|
|
</p>
|
||
|
|
</dd>
|
||
|
|
<dt><code>gdb-8.3/gdb</code></dt>
|
||
|
|
<dd><p>the source specific to <small>GDB</small> itself
|
||
|
|
</p>
|
||
|
|
</dd>
|
||
|
|
<dt><code>gdb-8.3/bfd</code></dt>
|
||
|
|
<dd><p>source for the Binary File Descriptor library
|
||
|
|
</p>
|
||
|
|
</dd>
|
||
|
|
<dt><code>gdb-8.3/include</code></dt>
|
||
|
|
<dd><p><small>GNU</small> include files
|
||
|
|
</p>
|
||
|
|
</dd>
|
||
|
|
<dt><code>gdb-8.3/libiberty</code></dt>
|
||
|
|
<dd><p>source for the ‘<samp>-liberty</samp>’ free software library
|
||
|
|
</p>
|
||
|
|
</dd>
|
||
|
|
<dt><code>gdb-8.3/opcodes</code></dt>
|
||
|
|
<dd><p>source for the library of opcode tables and disassemblers
|
||
|
|
</p>
|
||
|
|
</dd>
|
||
|
|
<dt><code>gdb-8.3/readline</code></dt>
|
||
|
|
<dd><p>source for the <small>GNU</small> command-line interface
|
||
|
|
</p></dd>
|
||
|
|
</dl>
|
||
|
|
|
||
|
|
<p>There may be other subdirectories as well.
|
||
|
|
</p>
|
||
|
|
<p>The simplest way to configure and build <small>GDB</small> is to run <samp>configure</samp>
|
||
|
|
from the <samp>gdb-<var>version-number</var></samp> source directory, which in
|
||
|
|
this example is the <samp>gdb-8.3</samp> directory.
|
||
|
|
</p>
|
||
|
|
<p>First switch to the <samp>gdb-<var>version-number</var></samp> source directory
|
||
|
|
if you are not already in it; then run <samp>configure</samp>. Pass the
|
||
|
|
identifier for the platform on which <small>GDB</small> will run as an
|
||
|
|
argument.
|
||
|
|
</p>
|
||
|
|
<p>For example:
|
||
|
|
</p>
|
||
|
|
<div class="smallexample">
|
||
|
|
<pre class="smallexample">cd gdb-8.3
|
||
|
|
./configure
|
||
|
|
make
|
||
|
|
</pre></div>
|
||
|
|
|
||
|
|
<p>Running ‘<samp>configure</samp>’ and then running <code>make</code> builds the
|
||
|
|
included supporting libraries, then <code>gdb</code> itself. The configured
|
||
|
|
source files, and the binaries, are left in the corresponding source
|
||
|
|
directories.
|
||
|
|
</p>
|
||
|
|
<p><samp>configure</samp> is a Bourne-shell (<code>/bin/sh</code>) script; if your
|
||
|
|
system does not recognize this automatically when you run a different
|
||
|
|
shell, you may need to run <code>sh</code> on it explicitly:
|
||
|
|
</p>
|
||
|
|
<div class="smallexample">
|
||
|
|
<pre class="smallexample">sh configure
|
||
|
|
</pre></div>
|
||
|
|
|
||
|
|
<p>You should run the <samp>configure</samp> script from the top directory in the
|
||
|
|
source tree, the <samp>gdb-<var>version-number</var></samp> directory. If you run
|
||
|
|
<samp>configure</samp> from one of the subdirectories, you will configure only
|
||
|
|
that subdirectory. That is usually not what you want. In particular,
|
||
|
|
if you run the first <samp>configure</samp> from the <samp>gdb</samp> subdirectory
|
||
|
|
of the <samp>gdb-<var>version-number</var></samp> directory, you will omit the
|
||
|
|
configuration of <samp>bfd</samp>, <samp>readline</samp>, and other sibling
|
||
|
|
directories of the <samp>gdb</samp> subdirectory. This leads to build errors
|
||
|
|
about missing include files such as <samp>bfd/bfd.h</samp>.
|
||
|
|
</p>
|
||
|
|
<p>You can install <code><small>GDB</small></code> anywhere. The best way to do this
|
||
|
|
is to pass the <code>--prefix</code> option to <code>configure</code>, and then
|
||
|
|
install it with <code>make install</code>.
