Subject Re: need help on cassandra client

HI Cassam,

I'm using the perl Thrift API against 0.6.4 currently.

It sounds like you are having trouble getting thrift installed and/or
getting the perl bindings built.  If you already have thrift installed, you
can just run:

% thrift --gen perl interface/cassandra.thrift

The libraries are now in gen-perl/Cassandra*

You can copy those to your perl directory of choice.

Once you have the libraries installed, you should be able to run the sample
code from http://wiki.apache.org/cassandra/ThriftExamples#Perl to connect.


HTH,
Dave Viner
