<p>Hello everyone,</p>
<p>I've been following the Tutorial for building tools using LibTooling and LibASTMatchers:</p>
<p><a href="http://clang.llvm.org/docs/LibASTMatchersTutorial.html" target="_blank">http://clang.llvm.org/docs/LibASTMatchersTutorial.html</a></p>
<p>I didn't accomplish the Step 0 as I had followed the "getting started guide" before to get llvm and clang. Then, everything was right until I reached to the instruction:</p>
<br/>
<pre style="overflow-x: auto; overflow-y: hidden; border: thin dotted #0c3762; margin: 0px 0px 12px; padding: 0.8em; background-color: #f0f0f0; color: #333333;">cmake -G Ninja ../llvm -DLLVM_BUILD_TESTS=ON</pre><br/>
<p>Then, I got the next errors:</p>

</blockquote><p>What's happening?</p>
<p>By the way, the directory would be ../../llvm, wouldn't it? I'm in /usr/llvm/build and when I write ../llvm it says: "The source directory /usr/llvm/llvm does not exist" </p>
<p>Thanks in advance,</p>
<p>Pedro.</p>
