<p>Thank you very much, Manuel, but should I have to make again the rest of the instructions?</p>
<p>I made what you told me and now, when I run</p>

<p><span style="font-size: 12.727272033691406px;">Do you think i should start from scratch?</span></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>

</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>
