Building mod_perl for authentication

I've now tried various version of Perl (5.10.1, 5.12.4, 5.14.1), and various
version of Apache, but I'm unable to get Apache to run when mod_perl is
installed.

The error logs show
symbol lookup error: /usr/local/lib/perl5/site_perl/5.14.1/x86_64-
linux/auto/ModPerl/Util/Util.so: undefined symbol:
Perl_xs_apiversion_bootcheck

This is from an earlier attempt to test more recent versions of Perl, which
seemed to do everything I need OK. That led me to remove ./site_perl/5.14.1
altogether, so at least I'm able to run Apache version 2.2.21 with Perl 5.12.4
and mod_perl 2.0.5.

However authentication still doesn't work. When I call $r->user in my
authenticaion script for a URL that uses basic authentication, I don't get the
login pop-up at all, and $r->user returns a value of ' (single quote)

when I run make test in mod_perl, the logs show:

Any thoughts on why this would suddenly stop working? Also, is there any
reason not to try and use Perl 5.14.2 with mod_perl?

Thanks,
Dan

Re: Building mod_perl for authentication

You should be able to run 5.14.1 with 2.06-dev available on
http://perl.apache.org.

If that doesn't work, I'd suggest posting your handlers to this list.

Looking at that symbol error though, it suggests that you may have
built mod_perl with a different binary build than it is being run
with. Undefined symbols are generally an indication of incompatible
Perl internal apis.

What Fred said. Take a look at perlbrew for building different
versions, for development at least.
