Bingo! -----Original Message----- Neale,
As far as I can see, the compiler is bitching that there is no != operator
defined for the iterator types on either side of the second argument to the
for() clause.
A suggestion: try expressing that 2nd arg to the for() clause as
!( i == data.end_roots() )
If there is an equality method defined for those objects, this should
uncover it. If that doesn't work, try asking the author for a fix. Chances
are you're not the only who will find (or has found) it.
