Can't locate object method "is_threaded" via package "Apache2::MPM"

["michael watson (IAH-C)" <mi...@bbsrc.ac.uk>]

I'm running Apache/2.2.4 (Unix) mod_perl/2.0.3 Perl/v5.8.0 configured.

BEGIN in Apache2::SizeLimit has the code:

    die "Apache2::SizeLimit at the moment works only with non-threaded
MPMs"
        if Apache2::MPM->is_threaded();

Yet if I run:

%> perl
use Apache2::MPM;
print Apache2::MPM->is_threaded();

I get:

Can't locate object method "is_threaded" via package "Apache2::MPM" at -
line 2.

The site I am trying to install relies on a modperl startup script, and
it is failing because it cannot find the is_threaded method in
Apache2:MPM.

What am I missing?

Thanks
Mick

nothing wrong with that.

of course - you can't really do much with Apache2:: modules outside of a
running mod_perl environment.  in this case Apache2::MPM::is_threaded()
is an constant subroutine created at runtime when mod_perl can query the
running Apache server and figure out whether it is using some threaded
mpm or not.

hopefully, you're typing Apache2::MPM with two colons ;)

if you have the mp2 sources and build available you can see Apache2::MPM
exercised by doing this:

  $ t/TEST t/api/query.t -v

the source for which is here

  t/response/TestAPI/query.pm

short of that, you might want to perldoc the Apache2::MPM manpage and
try calling show() in your startup script (in addition to is_threaded())
and see what happens.
