I had a LOT of trouble getting AuthDBI and modperl to work with
apache without segfaulting. I thought I would post how I got it to
work. YMMV
The solution came from someone's suggestion on the list to go back to
mod_perl-1.21_03. Unfortunately, this version would not compile with
a thread-enabled perl, so I tried one of the CVS "bleeding edge
versions". This finally worked.
Here is my final configuration:
+ Solaris 2.6
+ perl-5.6.0(with threads, with no large file support, with the cop.h
patch people posted)
[I'll include the patch at the end, but I don't think it was the
reason that it started working. Its something that I changed early
on that didn't have any effect. I'll include it anyway]
+ mod_perl-1.24-dev(20000920161934), compiled with EVERYTHING=1
+ apache-1.3.12,
"--activate-module=src/modules/perl/libperl.a" \
"--enable-module=so" \ in config.status
[possibly a --with-layout= here as well]
+ mysql-3.22.32
+ DBI-1.14
+ ApacheDBI-0.87
Basically the steps are to already have perl, mysql, DBI, ApacheDBI,
compiled and installed, including whatever else each package requires.
Then I untarred a new copy of apache, and copied and ran a
config.status (that I saved earlier) into the tree with the above
parameters, although you could just as well run ./configure with
those options. Then I untarred mod_perl, and edited the Makefile.PL
so that it ran config.status instead of its using its (broken) method
of configuring apache that allows for very little customization.
I'll include a diff at the end -- its just a small hack and might break
something else for you.
Then I ran perl Makefile.PL EVERYTHING=1 DO_HTTPD=1 in a newly
untarred copy of modperl from CVS (version above), Note that in my
experience mod_perl won't build correctly with apache unless you do
everything from mod_perl. So I ran a make there, and after doing
some tests, finally a make install in both the mod_perl and apache
directories.
And those are the exact steps I followed.
As a bonus I was able to get php-4.0.2 to run concurrently with
mod_perl and DBI as long as I built it as a module and made certain
that the perl sutff was loaded before the LoadModule and AddModule
lines for php.
So far apache hasn't died with a segfault and one of my tests was a
php script that did a mysql_connect() and pulled a list of tables,
running from an AuthDBI protected directory.
