Undefined subroutine &Scalar::Util::weaken

Mathew_Walker · December 30, 2004, 5:52pm

I’ve finally stumbled along enough to get things working (gotta love the
list archives), however when I click TOOLS from the main menu on the left, I
get the following errror. A little direction would be greatly appreciated.
To the best of my ability, I can’t find any glaring errors.

Try reinstalling Scalar::Util. It turns out that the “pure perl” version
of the module doesn’t have the ‘weaken’ method.

Mathew_Walker · December 30, 2004, 10:04pm

unfortuntely that did not do the trick.

No change in behaviour.

I also see similar errors in the /var/log/messages when it should be sending
emails about my first test ticket. example:

Reading the Scalar::Util.pm I found this quote “By default Scalar::Util does
not export any subroutines”… This could explain my problem but what is the
proper way to correct it?

Rajesh_Menon · January 18, 2005, 8:17pm

Hello All,

I am running RT 3.2.2 on RedHat Enterprise Linux. No emails are being sent
out of RT, but tickets are getting created. I see the following error
message in the /var/log/messages file whenever RT tries to send out an
email.

Undefined subroutine &Scalar::Util::weaken

I saw some earlier posts on this. I am wondering if anyone found a solution.
I will really appreciate any help.

Thanks to Mathew Walker’s (lmw94002@hotmail.com) suggestion, I fixed the
problem. I recompiled mod_perl and apache … that did the trick!!. It is
working without any problems now.

Only mod_perl & apache and that did the trick? Did you upgrade its
versions? What system do you have? Was it distro packages before? Give
us more info about your distro.

This question should be documented on the wiki.

Rajesh_Menon · January 24, 2005, 3:34pm

I am running RedHat Enterprise AS 3.0 on a Dell PowerEdge 2650 server.
Apache version is 1.3.31 and mod_perl is 1.29. The default version of perl
is 5.8.0 (came with RedHat). RT was using this version before. I think an
update of packages messed it up.

I didn’t have to upgrade anything. All I did was to re-compile mod_perl and
apache. Also I recompiled RT to use perl 5.8.6 (which I installed on an
alternate location leaving the default perl intact).

Hope this answers your question.

Hello,

I’m having a problem lately with RT. None of my scripts seem to be
working. I recently had to reinstall the operating system RT was running
on. I’m using 3.4.5 on Debian Etch.

All my scripts seem to terminate with this error:

“[error]: Scrip Prepare XX died. - Undefined subroutine
&Scalar::Util::weaken called at
/usr/share/request-tracker3.4/lib/RT/Action/Generic.pm line 108.”

Reading through the archives I saw a similar post that was fixed by
updating Scalar::Utils to 1.19. Mine was already at 1.19 so I decided to
reinstall it with “cpan -fi Scalar::Util”
No change to the error message. Tickets come in and go into the right
queues but the no one is notified and the requestor doesn’t receive any
acknowledgment of his submission.

Any ideas what to look next?

Thanks.

-Martin Ekendahl

Hello list,

I was using RT on my production server successfully. We were not using RT from sometime. We decided to use RT from today. Tickets are generating and getting resolved, all things are working well except the email parts. No email is going outside or coming to RT. In log i am seeing the error

[error]: Scrip Prepare 9 died. - Undefined subroutine &Scalar::Util::weaken called at /opt/rt3/lib/RT/Action/Generic.pm

[error]: Scrip Prepare 10 died. - Undefined subroutine &Scalar::Util::weaken called at /opt/rt3/lib/RT/Action/Generic.pm line 107

I gone through the archives and followed some answers like upgrading scalar::utils. But this package is already updated.

Please help me out. Operating system on which RT is installed is Centos-5.

Looking forward to some help.

Thanks & Regards
Bijayant Kumar

If i remember correctly, Centos is one of those distros that decided it was a
good idea to default to the perl-only implementation of Scalar::Util, but you
need the XS support for weaken.

You say you’ve upgraded scalar::utils. Was that through CPAN? If so, did you
make sure to answer yes to the XS question?

I have tried to upgrade through CPAN only, but it said that package is already updated. After some more googling i did

perl -MCPAN -e ‘install “G/GB/GBARR/Scalar-List-Utils-1.18.tar.gz”’

and it solves the problem of mail.

But now i am facing another very strange problem.
The autoreply greeting message that i am getting is very strange.
In a mail the upper part contains greeting message with ticket id, and at the bottem another greeting mail written with some another ticket id that were never being created.

Did you or anybody faced the same problem. Please suggest some thing to overcome from this problem.
