<p>I'm following <a href="http://clang.llvm.org/get_started.html" target="_blank">http://clang.llvm.org/get_started.html</a> and i have a problem in the step 6. Build llvm and clang.</p>
<p>When I run ../llvm/configure</p>
<p>I got the next error:</p>

<p>I was looking for information and came across with these two threads:<br>

<p>If I do<br>
$which clang++<br>
/usr/bin/clang++</p>
<p>And<br>
$g++ --version<br>
g++ (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3<br>
$which g++-4.6<br>
/usr/bin/g++-4.6</p>
<p>So i rerun <br>
../llvm/configure CXX="/usr/bin"</p></div></blockquote><div><br>I always thought CC and CXX needed to point at the compiler *directly*, and not just the path the compiler sits in (especially when there are several compilers sitting there).<br>
<br>So I would say CC="/usr/bin/clang" and CXX="/usr/bin/clang++"<br><br>-- Matthieu<br> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div>
