Re: Error: Symbol myTree is not defined in current scope sphericalLEFS60.cc:14

Hi,

this might be caused by your library being linked against libTree (and all the other libraries). This will cause a re-load of libTree in the middle of your script, and its dictionary will be in a funny state. We were already planning to tackle this one, hopefully in January.

I'm glad you found a work-around for now. Thanks for sending the detailed output!

Cheers, Axel.
