<p>Hi Brecht,</p>
<p>Building llvm and osl with RTTI doesn't change anything (and is a pita ;)</p>
<p>The class/struct inconsistency was fixed/committed, but doesn't do much other than remove some warnings.</p>
<p>Thanks,<br>
Dalai<br>

It seems RTTI was disabled in CMake but not in SCons.<br><br>Brecht.<br><br>On Tue, Sep 4, 2012 at 11:43 PM, Dalai Felinto <<a href="mailto:dfelinto@gmail.com" target="_blank">dfelinto@gmail.com</a>> wrote:<br><blockquote type="cite">
Hi there,<br><br>I'm helping Jens to get OSL 1.2 to work on OSX as well. OSL is<br>building and Blender builds as well. However we are now stumbling into<br>a strange problem.<br><br>When rendering with OSL we get the errors:<br>
