Just use GCC and follow the alternative directions for getting ghc to point at a real GCC.  They&#39;re linked to from the Mac Haskell platform page as the alternative directions.  <span></span><br><br>On Saturday, March 1, 2014, Richard Cobbe &lt;<a href="mailto:cobbe@ccs.neu.edu">cobbe@ccs.neu.edu</a>&gt; wrote:<br>

<a href="https://gist.github.com/tibbe/8448715" target="_blank">https://gist.github.com/tibbe/8448715</a>) to try to get GHC 7.6.3 (part of<br>
Haskell Platform 2013-2.0.0) working with XCode 5.0.2 on a MacOS 10.8.5<br>
machine.  Things look good, but I have two questions:<br>
<br>
Question 1: How do I know this worked?  I tested it by modifying a package<br>
that I&#39;m writing so that it requires CPP to build correctly, and<br>
successfully built it with &quot;cabal clean; cabal configure; cabal build&quot;.<br>
(More details available on request.)  Does that mean I&#39;m in good shape?<br>
<br>
(I&#39;m asking because I was never entirely clear on what the incompatibility<br>
was; all I know is that it has something to do with cpp.)<br>
<br>
Question 2: Is there any harm in adding -Wno-return-type to extraClangArgs<br>
in ghc-clang-wrapper?  This silences an annoying but apparently harmless<br>
warning I get from &quot;cabal configure&quot;.<br>
<br>
Thanks,<br>
