Pure Virtual Function crash when developing a nuke OP with OCIO / OpenColorIO API

Yanli Zhao <yanli...@...>

For some reason, I need to write a pixelOp similar to OCIOFileTransform with OCIO API. But when I add just one simple line such as "OCIO::GetCurrentConfig()", I got a crash with the terrible "Pure Virtual Function" error. I was wondering that maybe I was linking the wrong version of OCIO. Has anyone met with similar issues? I'm developing plugin for Nuke 10.0v5 with OCIO 1.0.9 on Linux.
