Marshal Problem

Ruby
1

Hi,

I’ve got a serialized object that I am trying to read back in with
Marshal. When it reads the class back in, it complains with the
following message:

undefined class/module ;

This is running on windows. Under Mac OS X, everything works fine
(Note: I serialize and de-serialize on the same platform, so it’s not
a cross platform issue.)

Anyone have any clues as to why it is looking to resolve a class
called “;” from the serialized file?

Thanks,
Bob E.

What are the ruby versions? Do you have the same classes loaded on
each side?

Hi Eric,

The Mac OS X version, which works is 1.8.4 (2005-12-24). The windows
version is ruby 1.8.4 (2005-12-24) [i386-mswin32].

The same classes are used to dump and load, from the same irb session
even.

Hi,

The objects involved were fairly complex, so I will try to create a
simpler case that exhibits the problem.

Can you show us how to reproduce the problem?

Hi,

Following up. I finally got back to this issue, and now everything
works fine.
I believe the problem may have had to do with reading and writing the
files that contained the marshalled objects without using the binary
flag.

Thanks for your help,
Bob
