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: *** The following error entry is expected and harmless *** [Sat Oct 08 08:27:58 2011] [error] [client 127.0.0.1] custom die hook: Undefined subroutine &TestError::runtime::no_such_func called at /home/daxtell/src/mod_perl-2.0.5/t/response/TestError/runtime.pm line 150.\n [Sat Oct 08 08:28:03 2011] [error] [client 127.0.0.1] user stas: authentication failure for "/": Password Mismatch *** The following error entry is expected and harmless *** [Sat Oct 08 08:28:08 2011] [error] [client 127.0.0.1] need AuthName: /TestModperl__setauth [Sat Oct 08 08:28:15 2011] [error] [client 127.0.0.1] Undefined subroutine &TestHooks::error::bomb called at /home/daxtell/src/mod_perl-2.0.5/t/hooks/TestHooks/error.pm line 21.\n [Sat Oct 08 08:28:15 2011] [error] [client 127.0.0.1] Undefined subroutine &TestHooks::error::bomb called at /home/daxtell/src/mod_perl-2.0.5/t/hooks/TestHooks/error.pm line 21.\n 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
