VTK does *not* require Obj-C garbage collection.  On OS X, a process is either garbage collected or not.  But library code (like VTK) can be written to support one, the other, or both.  VTK supports both, which is what -fobjc-gc means.  If VTK required GC, it would use -fobjc-gc-only.

I'm surprised that VTK's use of -fobjc-gc causes you any problem.  What exactly is the error you are seeing?

Cheers,
