Обсуждение: Postgres' DBI(Pg) problem

Hi !
 
I have installed :
 
PostgreSQL 7.0
+ DBI and DBD::Pg

+ the environment vars : LD_LIBRARY_PATH and PGLIB are set to my ./pgsql/lib directory
+ Apache 1.3.22 without "mod_perl" installed
 
When I write a program like :
 
#!/bin/perl -w
 
use DBI;my $dbh, $sth;
$dbh = DBI->connect("dbi:Pg:dbname=researchdb") or die $DBI::errstr;$sth = $dbh->prepare("insert into course
values('$v1','$v2')") or die $DBI::errstr; 
...
...
...
That runs perfect.
 
 
When I am trying to write a CGI script like this which will run under apache :
 

#!/bin/perl -w
use strict;
use CGI;
use CGI::Carp qw(fatalsToBrowser);
use DBI;
my $dbh, $sth, $query;
$query = new CGI;
$dbh = DBI->connect("dbi:Pg:dbname=researchdb") or die $DBI::errstr;$sth = $dbh->prepare("insert
into answersvalues('test1', 'test2');") or die $DBI::errstr; 
..
print $query->header( ....
..
..
 
It gives me the following error in the browser.

Hi

did you set your LD_LIBRARY_PATH in your apache-config? You should put a "SetEnv LD_LIBRARY_PATH (wherever your . is)/pgsql/lib). And reload or restart apache of course.
