Andi Vajda resolved PYLUCENE-16.
--------------------------------
Resolution: Fixed
rev 1220359
> can't wrap weka because of attribute and method with the same name
> ------------------------------------------------------------------
>
> Key: PYLUCENE-16
> URL: https://issues.apache.org/jira/browse/PYLUCENE-16
> Project: PyLucene
> Issue Type: Bug
> Environment: Ubuntu Linux 10.04, Python 2.6, Java 6, PyLucene 3.5
> Reporter: Bill Janssen
>
> I'm trying to wrap Weka, a popular machine learning system, with PyLucene.
> One of the Weka classes, weka.core.Utils, has a public static variable,
> and a public static method, with the same name (see below). When I
> compile it, JCC has no way to say that, and I get the following:
> In file included from build/_test/__wrap__.cpp:5983:
> build/_test/test.h:36: error: declaration of 'static jdouble
> test::log2(jdouble)'
> build/_test/test.h:32: error: conflicts with previous declaration 'jdouble
> test::log2'

> member of 'class test'
