No. The LCL version has just a few more properties, like a compare method and some nice to have wrapper classes. Maybe the LCL goodies code should be copied to the FCL version. I would prefer using fpc to avoid LCL dependency. No problem. Just copy the TPointerToPointerTree code and adjust it to use the AVL_Tree unit. I hope that someday the fpc generics are good enough to create a generic AVL tree.

Re: [lazarus] Class to store pointer values indexed by pointers
Hi, There is a licencing difference : fpc/AVL_Tree is GPL 2 ( or above ) while lcl/AvgLvlTree is _modified_ LGPL . Is there a reason for this ?
