Message-ID: <200104030018.f330IXK69300@postgresql.org> (raw)
Hi,
I am trying to get webcal 3.03,
(http://bulldog.tzo.org/webcal/webcal.html) running on my Red Hat Linux
6.1 system.
I am using PostgreSQL 7.1beta5, and perl5.00503.
I am a perl newbie, but familiar with webservers and postgres.
Caveat: I know what @INC does, but I have no idea how to set it.
At a suggestion from then net, I have recently (today) loaded DBI::DBD
and Bundle::DBI
perl -MCPAN -e 'install DBI::DBD'
perl -MCPAN -e 'install Bundle::DBI'
I then followed the instructions in
postgresql-7.1beta5/src/interfaces/perl5/README, and installed Pg.pm.
When I then tried to run webcal, Apache/Webcal complained that:
install_driver(Pg) failed: [Mon Apr 2 17:13:01 2001] webcal.cgi: Can't
locate DBD/Pg.pm in @INC (@INC contains: /home/httpd/cgi-bin/webcal
/usr/lib/perl5/5.00503/i386-linux /usr/lib/perl5/5.00503
/usr/lib/perl5/site_perl/5.005/i386-linux
/usr/lib/perl5/site_perl/5.005 .) at (eval 4) line 3. Perhaps the
DBD::Pg perl module hasn't been fully installed, or perhaps the
capitalisation of 'Pg' isn't right. Available drivers: ADO, ExampleP,
Multiplex, Proxy. at /home/httpd/cgi-bin/webcal/webcal_io.pm line 282
Investigating, I found that Pg.pm had been placed in
/usr/lib/perl5/site_perl/5.005/i386-linux and not in
/usr/lib/perl5/site_perl/5.005/i386-linux/DBD
So I linked from one to the other
ln -s Pg.pm DBD/Pg.pm
When I rerun webcal, Apache/webcal tells me:
DBD::Pg initialisation failed: [Mon Apr 2 17:15:31 2001] webcal.cgi:
Can't locate object method "driver" via package "DBD::Pg" at
/usr/lib/perl5/site_perl/5.005/i386-linux/DBI.pm line 520. Perhaps the
capitalisation of DBD 'Pg' isn't right. at
/home/httpd/cgi-bin/webcal/webcal_io.pm line 282
This is what DBI.pm looks like:

$drh = eval { $driver_class->driver($attr || {}) };
Can you offer me some tips or advice on how to proceed?
Thank you,
