But this is the mod_perl mailing list. It is the place to which one sends reports of bugs or problems with mod_perl. I sent such a report, citing this undefined symbol when building mod_perl2.
It is hard for me to imagine that the fact that I gave the perl build process a list of directories to append to @INC should affect the presence or absence of a symbol in the resultant perl binary. The only time that perl will even consult those directories are when it is looking for a module name that it doesn't find in the 5.10.1 directories. There is not much in the modules in @INC directories that is necessarily connected to "major versions of perl". Of course it's possible that some older modules may not work as well with a new version as with older versions, but in this case it's the responsibility of the author to work out and release a new version that will hopefully work equally well with the older and newer perls. And any module can specify the oldest version of perl (or other modules on which it depends) that it will work with. I always maintain my perl modules with -MCPAN's r command, and upgrade those for which new versions are available on a regular basis. I don't know the command 'ack' that you used in your work below, but it looks like it examined source files in a subdirectory of your home directory (~). Do you have a perl5.10.1 binary that you have used in conjunction with mod_perl2? If so, can you please cd to the directory that contains that binary (/usr/local/bin?) and enter a grep command like I used: grep Perl_pad_sv perl5* and see if your 5.10.1 binary contains the symbol? And if so, how did your binary come to be? Thanks, cmac On Sep 1, 2009, at 9:32 PM, Fred Moyer wrote:

And it has always worked, with the single exception of building mod_perl2 this time. All of the perl scripts and modules on my site work well under the new 5.10.1.I don't know enough here to say one way or the other about this, but you're mixing major versions of perl (5.10 vs 5.8) The Perl 5 Porters would be a good place for these issues. But you are seeing unresolved symbol errors when trying to use different major versions of Perl. That is enough circumstantial evidence that if I were in your shoes, I'd use a separate 5.10 install. But p5p could probably give a more educated analysis of this.Aside from the pain of re-downloading all kinds of modules as they prove to be needed over the next year or so, I know there are items in the 5.8.7 libraries from my Internet Hosting Provider, that are needed to run software from the IHP. I can certainly build a 5.10.1 without the otherlibs, and locate it somewhere else than in /usr/local/bin. Will that process completely replace all of: /usr/local/lib/perl5/5.10.1/i386-freebsd /usr/local/lib/perl5/5.10.1 /usr/local/lib/perl5/site_perl/5.10.1/i386-freebsd /usr/local/lib/perl5/site_perl/5.10.1 ?? If so, I suppose could copy them somewhere before the build, and copy them back after the build. In "Non-Boolean Build Options" on http://perl.apache.org/docs/2.0/user/install/install.html, I don't see a command to tell the mod_perl build process to use a particular perl. If I say $perl_other Makefile.PL in the modperl-2.x directory, does that do it? Thanks for being there, cmac On Sep 1, 2009, at 5:58 PM, Fred Moyer wrote:Can you please cc the list on all replies?
