Hi all,

I bought the May 2005 issue of Dr. Dobb's Journal just so that I could read John Graham-Cumming's (excellent) article describing a perl implementation of a simple naive Bayesian classifier. I bought a magnifying glass just so that I could read the listing (no kidding!). I checked pretty carefully for typos, but it isn't running on my machine (Mandrake 10.0). I think the problem might be that I am lacking a certain perl library; the second line in the perl script is

# use DB_File

and using locate I can find no trace of any "DB_File" on my machine. (Is that a really silly comment? Is DB_File in fact some kind of library which I would need to run the perl script in question, or is it something else? I have no idea, because I am no programmer--- as I said, I bought this issue of DDJ only in order to try to enter and use this perl script.)

I can't find DB_File in the Debian archives, or figure out whether this is something I need and if so where to get it, or whether my problem is due to something else. Any suggestions?

TIA, Peufelon

Don't be so naive

Could you elaborate? Your answer isn't very helpful to me as it stands.

You're most likely missing some required perl modules. There are a few ways to resolve these dependencies.

1. Download the module from http://www.cpan.org , compile and install it manually or
2. Use the automated method via the "perl -MCPAN -e shell" command

All of the above is documented at the cpan web site http://www.cpan.org/misc/cpan-faq.ht...l_Perl_modules

Joke....I didn't think there could be any confusion

Thank you, Mad Luther, I found the module. This was very helpful!
