Clang Installation
<p>I am trying to use Clang.</p>

<p>First, I downloaded the first two source files (LLVM source code + Clang source code) from <a href="http://llvm.org/releases/download.html#3.8.1" rel="nofollow">here</a>, under section "download llvm 3.8.1".</p>

<p>Then, I extracted them, and renamed the obtained extracted directories to llvm and clang (respectively). Then, I put the clang directory inside llvm/tools.</p>

<p>Finally, I followed the instuctions <a href="http://clang.llvm.org/get_started.html" rel="nofollow">here</a>, under the section "building Clang and working with the code", in the subsection "on Unix-like systems".</p>

<p>BTW, the reason why I renamed the directories to clang and llvm as in these insturctions these are the names of the directories, so I guess I should rename them.</p>

<p>And in step 9 ("try it out"), when I typed "clang --help", I got the message:</p>

<p>"The program 'clang' can be found in the following packages:</p>

<ul>
<li>clang 3.3</li>
<li>clang 3.4</li>
<li>clang 3.5</li>
</ul>

<p>Try sudo apt-get install &lt; selected package >"</p>

<p>This means that the installation failed.
Why? What else should I do?</p>

<p>Thanks in advance!</p>
