title: How to install clang pre-built binaries ubuntu 12.04
body: <p>I am very new to linux, and don't know where I need to put Clang pre-built binaries <a href="http://llvm.org/releases/download.html#3.3" rel="nofollow noreferrer">http://llvm.org/releases/download.html#3.3</a>  .  I download it, unpack with mouse, and add path to /bin to my $PATH, and path to /lib to $LD_LIBRARY_PATH, and add *.conf with path to my /lib to /etc/ld.so.conf.d . I even reboot my notebook.<br>
  ...but still cant build my simple program with Code::Blocks GCC (error: /home/aadgrand/tmp/LLVM-3.3/final/llvm.src/lib/Support/Signals.cpp - undefined reference to `dladdr'). 
  Text of the test programm:</p>
  
  <pre><code>#include &lt;iostream&gt;
  #include "llvm/IR/Module.h"
  #include "llvm/IR/LLVMContext.h"
  using namespace std;
  
  int main()
  {
      llvm::LLVMContext &amp;c = llvm::getGlobalContext(); // error line
      cout &lt;&lt; "Never printed" &lt;&lt; endl;
      return 0;
  }
  </code></pre>
  
  <p>What else I need to do? Maybe I need to use *.sig-file? Hm? </p>
  
  <p>Same question as <a href="https://stackoverflow.com/questions/17045954/how-to-install-clang-using-precompiled-binaries">How to install CLang using precompiled binaries?</a> . 
  Sorry for repeat, but it is really very interesting and important. </p>
  
  <p>===== UPDATED ======</p>
  
  <p>I've just insalled llvm-3.1, same error like with llvm-3.4 (from pre-built binaries):  </p>
