Please include the lines you added here so that I can I help you
debug this.
Please see the diff at the end of this email.
Did you end all lines with \ ?
> Can I use most recent version (SVN?) if I have
dev-java/lucene-3.5.0 installed here?
Most recent version of what ?
JCC ? or both ?
Either way, yes, although trunk is based on the upcoming lucene 4.3
relea
se and has a different API from lucene 3.x so you need to migrate
your application code using PyLucene to the new API.
Andi..
Sorry, but I don't understand this. If trunk PyLucene expects a new
Lucene API how can it work with Lucene-3.5.0 which still has
the old API ?
Many thanks,
Andi,
Helmut.
