Re: Segfault on DBI-Connect (was mod_perl and AuthenDBI headaches)

[Drew Degentesh]

Hi,

after some browsing of the [EMAIL PROTECTED] archives, I see now that my
AuthDBI problem is the same as this thread (Segfault on DBI-Connect). I
tried the workaround suggested by wil (*sock=0 before mysql_init(sock)) to
no avail.

Here's a backtrace from gdb httpd -X. Has any headway been made on this
problem? If you need more information, let me know...

mod_perl and AuthenDBI headaches

[Drew Degentesh]

Hello,

My setup is:

Redhat 6.1 (Linux 2.2.12-20RS )
Apache 1.3.12 (compiled from source)
mod_perl: 1.12 (compiled from source)
ApacheDBI-0.87
DBI-1.13
mysql  Ver 9.36 Distrib 3.22.27 (from distribution)
perl 5.005_03 (from distribution)
Msql-Mysql-modules-1.2211

I'm pulling my hair out trying to authenticate against a database. I keep
getting a segmentation fault immediately upon trying to connect to a
database (somewhere around line 245 of Apache/AuthDBI.pm). Ive tried tons of
workarounds...

I have no difficulties using DBI in a 'regular' perl script
(i.e.
#!/usr/bin/perl
use DBI;
DBI-connect( ...
)

...nor do I have any difficulties with mod_perl in general. Just AuthDBI.

When I compiled mod_perl I used EVERYTHING=1 and ALL_HOOKS=1. I enabled APXS
but mod_perl is not loaded as a dynamic library (though PHP4.0RC1 is...)

Any suggestions/co-lamenters?

Please help!
