Hi Tim, Thanks for the tips. Excuse my inexperience and this lengthy post. I hope this helps more than hinders! > > Not a lot to go on, here ... could you follow the instructions at > > http://www.k-3d.org/wiki/Testing_And_Debugging > > and post a backtrace? > > As an aside, I'm glad to hear someone's doing a regular 64-bit build ;) > OK, updated my local sources from CVS. I also changed the install to /opt/k3d to keep the binaries separated from other packages.
