<p class="MsoNormal"> Okay, got the latest nightly build and trying out the QT implementation (there’s a bug fix with destructor order in QT that I need). With the latest change (vtkTDxConfigure.h being copied), I can get the code to compile.
However, running into a new issue: The renderwindow isn’t built.<o:p></o:p></p>
