<h2>12.4 GDB finds only <code>.cc</code> source</h2>

<p><em><strong>Q</strong>: When I try to debug my C<tt>++</tt> programs, the debugger claims it can't
find the source file:</em>

<br><p>
<pre> file.cc: No such file or directory.
</pre>

<p><em>The source file <strong>is</strong> there, but it's called
<code>file.cpp</code>, not <code>file.cc.</code>  Why does this happen?</em>

<p><strong>A</strong>:  It's a bug in GCC 2.7.2.1 and earlier.  It erroneously assumes
that a C<tt>++</tt> source always has a <code>.cc</code> extension.  If you are using
GCC 2.7.2.1 or earlier, you'd better call your C<tt>++</tt> files <code>*.cc</code>. 
If this is unacceptable, you can work around this bug by invoking
<code>cc1plus</code> and the assembler pass manually.  The bug in GCC
manifests itself in that <code>cc1plus</code> is called with the option
<code>-dumpbase&nbsp;file.cc.</code>  If you replace this with
<code>-dumpbase&nbsp;file.cpp</code> (or whatever your extension is), the
debugger will happily find your sources.

<p>GCC 2.8.0 and later corrects this bug, so upgrading is also a solution.
