Trouble with Apache::DB
I have a newly installed Red Hat 8.0 system, with the
following characteristics:
* Perl v5.8.0
* mod_perl 1.27
* Apache 1.3.26
The build of mod_perl/Apache worked fine; the project
I had been working on before upgrading RH seems to run
ok. However, today I attempted to debug something
using Apache::DB and running with "httpd -X". I
received this error:
[error] No DB::DB routine defined at
/usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi/Apache.pm
line 4.
Now, nothing has changed with my project (i.e. the
Apache config is the same, the code is the same, etc),
only the version of Perl on the new system. I did
some tests using the regular perl debugger, and had no
problems.
Is there some incompatibility here, or is something
else wrong? Any help would be greatly appreciated.
Thanks,
--kip

Yes, I was using the stock RH perl. I did try
recompiling 5.8.0 with debugging support, as you
suggested, with no luck. I then tried recompiling
other versions of perl (like 5.8.0 RC2, RC1, 5.7.3),
with and without debugging support, also with no luck.
Finally, I just grabbed a 5.6.1 (since this all worked
on my other systems with 5.6.1) and put that on there.
I compiled without debugging support (and just used
almost all the defaults), recompiled mod_perl and
Apache, and that seems to have done the trick.
I still don't know what the problem is, whether it's
with perl, Apache::DB, RH, me, my cat... Anyway, I'll
have to use this workaround until I have more free
time.
Thanks to everyone for the suggestions!

I think someone recently mentioned on this list that you may need a Perl
with debugging compiled into it. Kip, are you using the stock Redhat Perl?
Maybe you should try recompiling with debugging enabled. That means you'll
need to recompile mod_perl as well. For my part, I haven't had a problem
with the Debian 3.0 or FreeBSD perl binaries.
Good luck,
William

I got a similar error a while back when I tried it with the same versions of
Perl, mod_perl, and apache (but on Mac OS X). I googled a while and all I
could come up with were some posts from internals hackers about perl data
structures getting mysteriously hosed for some unknown reason with this
collection of versions. I still haven't found a solution...
