title: Does libcxxabi makes sense under linux? What are the benefits?
body: <p>I'm trying to determine if building and using <a href="http://libcxxabi.llvm.org/"><code>libcxxabi</code></a> from the llvm project under linux makes sense.</p>
  
  <p>My build of <code>libcxxabi</code> is linked to</p>
  
  <pre><code>ldd libc++abi.so.1.0 
      linux-vdso.so.1 =&gt;  (0x00007fff2e0db000)
      libpthread.so.0 =&gt; /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fd658f0d000)
      librt.so.1 =&gt; /lib/x86_64-linux-gnu/librt.so.1 (0x00007fd658d05000)
      libc.so.6 =&gt; /lib/x86_64-linux-gnu/libc.so.6 (0x00007fd65893c000)
      libc++.so.1 =&gt; /path/where/clang/is // edited
      /lib64/ld-linux-x86-64.so.2 (0x00007fd6593ab000)
      libgcc_s.so.1 =&gt; /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007fd658465000)
  </code></pre>
  
  <p>and so it's using the <code>gcc_s</code> library, the GNU librt, and the only real difference is the fact that it's using <code>libc++</code> over <code>libstdc++</code>, but how good this really is ?</p>
  
  <p>Given the critical role of an abi library, I should go for <code>libcxxabi</code> under such platform ?</p>
  
  <p>My problem it's not about how to build this, or if this will work, but if this is a good idea <em>C++-wise</em>, what kind of benefits I can possibly get, or what kind of benefits you are getting if you are already using this.</p>
