<p>After CVS update, rebuilding gives the error "No rule to make target".</p>

<div class="answer">
<p>If the error is of the form:</p>
<div class="doc_code">
<tt>
gmake[2]: *** No rule to make target `/path/to/somefile', needed by
`/path/to/another/file.d'.<br>
Stop.
</tt>
</div>
<p>This may occur anytime files are moved within the CVS repository or removed
entirely. In this case, the best solution is to erase all <tt>.d</tt> files,
which list dependencies for source files, and rebuild:</p>
<div class="doc_code">
<pre>
% cd $LLVM_OBJ_DIR
% rm -f `find . -name \*\.d`
% gmake
</pre>
</div>
<p>In other cases, it may be necessary to run <tt>make clean</tt> before
rebuilding.</p>
