ePN (embedded Perl Nag) with Perl 5.8.0. Not broken on all OS ...

[Stanley Hopcroft]

Dear Ladies and Gentlemen,


I am writing to withdraw my earlier mistaken claim that Nagios-1.0 (and
probably Netsaint) with the embedded Perl interpreter (ePN), is broken
with Perl 5.8.0.

(This claim was based on seeing the embedded Perl simulator - mini_epn.c 
SEGV wtih Perl 5.8.0. In fact there was a coding error in mini_epn.c 
[not unfortunately visible in any of the Nag base code that can use 
Perl]).

I have ePN running on this FreeBSD 4.7-RELEASE host with the FreeBSD 
Perl 5.8.0 port.

pc09011# cd /usr/local/nagios
pc09011# bin/nagios -m

This is perl, v5.8.0 built for i386-freebsd

This Perl is built without _any_ thread support 

(usethreads=undef use5005threads=undef useithreads=undef 
usemultiplicity=undef)

So. it may be the case that the systems having problems with ePN are 
those systems that have Perls built with thread support, and there is a 
problem with Nag support for threaded Perls (or there are still problems 
with Perl threads).

I would like to hear from those that would like to spend some more time 
trying to deal with this problem.

Please would you send me

1 OS details (Name and major version)
2 Perl threaded details (perl -V | grep thread)
3 Whether or not you can try ePN with an unthreaded Perl

FWIW, none of the Perl plugins I am aware of takes advantage of threads. 
An unthreaded Perl would therefore work as well as a threaded one.

Yours sincerely.

Europe is the less, as well as if a promontory were, as well as if a
manor of thy friend's or of thine own were. Any man's death diminishes
me, because I am involved in mankind; and therefore never send to know
for whom the bell tolls; it tolls for thee...'
