[Mapserver-users] PERL mapscript undefined symbol woes

[Steve Lime]

I've not tried perl 5.8 with Swig. So, if they changed the guts of perl
which is where all
the undefined symbols live then that could be the issue. Have you tried
re-swigging the
the interface (cd mapscript/perl; swig -shadow -perl5 mapscript.i) file
with a brand new
version of Swig?

Greetings Listers,
    I have a Debian box with PERL5.8 and mapserver-3.6.5.  I have had 
great success in the past with this box, but something in my build went

awry.  The compile for mapserv and then perl/mapscript completed
without 
error.  The object is also generally useful when using dump.pl and even

some live map rendering under apache.  The symptom that I observed is 
that whenever the process needs to carp out something it segfaults and

dies.  I ran ldd with the -r option and observed an interresting clue 
(see below).  Does anyone have any ideas how the Perl_* symbols are 
defined?  Why would they not be found?  Should the list of *.so include

libperl.so?  Any ideas on getting out of this mess?
