Hi,
If you read the doc of the DB_File module you need to install Berkeley DB.
So why does this module work without installing Berkeley DB?
If there is a version of Berkeley DB which come with perl and if the case
what is the version number?
In fact I try to use DB_file data between several computers with different
OS, I don't understand really the rules of compatibility of data files
sometime it works with different versions of perl and sometimes not.
Please help me!
Arnaud.

No, you only need to install Berkeley DB if you don't already have it
installed on your system.

DB_File cannot work without an installed copy of Berkeley DB.

Berkeley DB does not ship with Perl.

That is a different question.
Berkeley DB data files have been designed to be portable between different
OS's, as long as the same version of Berkeley DB is used on each system.
The data file format used by Berkeley DB has changed over the years, so you
need to make sure that you are running DB_File built with the same version
of Berkeley DB on each OS.

Please log in for more thread options Thanks Paul,
Internet is amazing! What is better than to have an answer from the module
author!
You're right, for example for my cygwin version this is the 4.2 version
Berkeley DB which was installed by default with cygwin.
I have updated all my Berkeley DB with this version and now the behaviour is
the same on my different computers.
Best regards,
Arnaud.
