Re: Undefined symbol "Perl_pad_sv" building mp2

A bit more data on the problem reported below:

/build/modperl-2.0 $ grep -r Perl_pad_sv *
Binary file src/modules/perl/mod_perl.so matches
/build/modperl-2.0 $ ll src/modules/perl/mod_perl.so

-rwxr-xr-x 1 user wheel 1559168 Aug 29 21:22 src/modules/perl/mod_perl.so

/build/modperl-2.0 $ cd /usr/local/bin


/usr/local/bin $ ll perl5*

-rwxr-xr-x  1 root  wheel   951373 Jan  7  2009 perl5.8.9
/usr/local/bin $ grep -r Perl_pad_sv perl*
Binary file perl5.8.7 matches
Binary file perl5.8.8 matches
Binary file perl5.8.9 matches
/usr/local/bin $

So the symbol in the error message is wanted by the newly-built
mod_perl, but perl 5.10.1 does not include it.

Yes that's exactly what the error message says, but the mailing
list is so quiet that I wonder if my filters have started eating
its emails...

1. Problem Description:
I have upgraded to Apache 2.2.13 and Perl 5.10.1. Both seem tobe working
OK,
although Apache with using my old mod_perl 2.04 that uses perl5.8.9.


Have you rebuilt your mod_perl 2.0.4 instance from scratch using
5.10.1?  Undefined symbol warnings like this usually mean you are
trying to use a version of mod_perl that has been built with another
perl binary.

Suggest running make clean, then:

perl Makefile.PL MP_APXS=/path/to/my/httpd/apxs
make
make test

Yes, that is pretty much exactly what I've done. Here is thecommand file

(that precedes make):

#! /bin/sh
CFLAGS="-DVERIO -DVERIO_VPS"; export CFLAGS
LDFLAGS="-L/usr/local/lib"; export LDFLAGS
perl Makefile.PL MP_APXS=/usr/local/apache2/bin/apxs

make test in both the release mod_perl 2.0.4 and the latestsnapshot 2.0.5

gives the same error:

$ make test
cd "src/modules/perl" && make
/usr/bin/perl -Iblib/arch -Iblib/lib  t/TEST -clean
