Hello, I have a problem with Perl 5.6.0 on OS X 10.1.5. I am
using the Mapscript perl module and I need to connect to
PostgreSQL from the same script. I tried DBI/DBD::Pg and I also
have tried the Pg module that comes with PostgreSQL. Both fail at
runtime with "multiple definitions of symbol" error. At appears
all of these modules, and Perl itself, have been compiled with
-flat_namespace. All of these modules seem to work fine
independently. However, when mapscript module is combined with Pg
or DBD::Pg, it fails.
Any suggestions would be appreciated.
--script 1 --
#!/usr/bin/perl
use mapscript;
use Pg;
$conn = Pg::connectdb("dbname=aps");
die("ok");
