1. Download llvm from the official website (binaries or source). If you download the source compile it.<br></div>2. Put all of the files somewhere you find convenient (I use ~/.llvm)<br></div>3. Edit ghc.conf (not sure if the name is correct), to add ~/.llvm/bin/llc (in my case) and  ~/.llvm/bin/llvm where required. I don&#39;t remember the path, somewhere in lib in think. It&#39;s the file that is read when running ghc --info<br>


<br></div>It should work afterwards. Note that llvm3.4 is the latest llvm but is not tested on ghc (llvm3.3 is). I use 3.4 w/o issues though.<br></div><div class="gmail_extra"><br clear="all"><div>--  <br>Cp</div>
