<p class="MsoNormal">If I am not wrong, XCode 5 symlinks gcc to clang. (XCode 5 for Mavericks doesnt seem to support the GNU gcc). And so, it has no OpenMP support. <o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Also, on installing gcc, I was told that gcc will not be binary compatible with Apple's LLVM-gcc and so, updating some of the existing libraries down the road may have issues (I may be wrong here though).<o:p></o:p></p>

runtime by compiling it with gcc), I think you already have everything you need without building any compilers or compiler components.</span><o:p></o:p></p>

aren’t interested in (and don’t need) the experimental clang, or the runtime to support it.</span><o:p></o:p></p>
