<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">Hi David & VTKers,<div>At the time my program runs, __OBJC_GC__ is undefined and I can't find anywhere in my project, the VTK build, or my environment setting where it is either defined (or undefined). So, if the definition isn't hiding away somewhere, my understanding of it is that the PoolOfLastResort "hack" should be setting up a pool that can be subsequently autoreleased during Cocoa operations. I guess I need to now dig into the workings of CMake so as to understand what Sean is doing with his RogueResearch builds. Any further suggestions (Like Hey Corrie, buy the Cmake book!) will certainly be appreciated.</div><div>Corrie</div><div><br class="webkit-block-placeholder"></div><div><div><div>On Feb 22, 2008, at 9:55 AM, David Cole wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite">Look at the code around line 222 of VTK/Rendering/vtkCocoaRenderWindowInteractor.mm<br><br>If you are getting that message, then the vtkEarlyCocoaSetup constructor is probably not being called.
