Re: undefined symbol modperl_xs_sv2request_rec
The next release of apreq will contain a package called
APR::Request::Magic, for apps that are meant to be portable
between cgi and mp2. What you've reported isn't a bug in
apreq or mp2, it's a bug in how your app uses apreq. APR::Request::Apache2
shouldn't be used outside a running modperl server. If
you change your code to use APR::Request::Magic, it'll
work in both contexts.

Can you post the code and the httpd conf?

undefined symbol modperl_xs_sv2request_rec
A change in Module::Build recently brought it in line with
the behavior of ExtUtils::MakeMaker, which caused an error
to crop up in test cases:
# Error: Can't load
'/usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi/auto/APR/Request/Apache2/Apache2.so'
for module APR::Request::Apache2:
/usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi/auto/APR/Request/Apache2/Apache2.so:

... but only with `Build test` and not `prove -r t/`.
This is because $ENV{PERL_DL_NONLAZY} is now always set by
Module::Build::Base when running the test suite, which makes
it try to resolve all undefined symbols.
This only seems to happen in the test script trying to 'require'
packages that use Apache2::Request (libapreq2) but people seem
inclined to think it is a problem with mod_perl and not apreq.
Any ideas? Thanks. --mark--

perlrun explains PERL_DL_NONLAZY and why you'd set it to true for tests.
PERL_DL_NONLAZY
Set to one to have perl resolve all undefined symbols when
it loads a dynamic library. The default behaviour is to
resolve symbols when they are used. Setting this variable
is useful during testing of extensions as it ensures that
you get an error on misspelled function names even if the
test suite doesn't call it.
So the test is trying to tell you that modperl_xs_sv2request_rec is not
defined in your shared library.
Also, `prove -I blib` is not correct. You want `prove -b` which will pull in
blib/lib and blib/arch.

undefined symbol modperl_xs_sv2request_rec
A change in Module::Build recently brought it in line with
the behavior of ExtUtils::MakeMaker, which caused an error
to crop up in test cases that 'require_ok'.
# Error: Can't load
'/usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi/auto/APR/Request/Apache2/Apache2.so'
for module APR::Request::Apache2:
/usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi/auto/APR/Request/Apache2/Apache2.so:

... but only with `Build test` and not `prove -r t/`.
This is because $ENV{PERL_DL_NONLAZY} is now always set by
Module::Build::Base when running the test suite, which makes
it try to resolve all undefined symbols.
This only seems to happen in the test script trying to
'require' packages that use Apache2::Request (libapreq2) but
people seem inclined to think it is a problem with mod_perl
and not apreq.
