uClibc can be compiled with clang. You can try to use it if it works for you.<br>

<p>Hey all,</p>
<p><br>
</p>
<p><br>
</p>
<p><br>
</p>
<p>I was wondering if clang/LLVM has support to compile glibc in its entirety? The only thing I could find of recent was this thread saying the only way it could really be done is to use the dragonegg plugin with gcc...
