Hi Everyone,

I'm also experiencing some difficulties with Perl - i've spent the past 3 days trying to get this to work but i can't find any log, any error message etc ...

I've installed all the perl libs , but when i run the test script, it's just stay there indefinitely with no output,no error - this is the script : cat monetdb2.pl

#!/usr/bin/perl

use DBI();

my $dbh = DBI->connect('dbi:monetdb:');

my $sth = $dbh->prepare('SELECT * FROM env'); $sth->execute; $sth->dump_results;

I'm running monetdb with the following command: root@ulys:~# mserver5 --dbinit="include sql;" --dbname=demo --daemon=yes # MonetDB server v5.6.0, based on kernel v1.24.0 # Serving database 'demo' # Compiled for i686-pc-linux-gnu/32bit with 32bit OIDs dynamically linked # Copyright (c) 1993-2008 CWI, all rights reserved # Visit http://monetdb.cwi.nl/ for further information #warning: please don't forget to set your vault key! #(see /root/MonetDB/etc/monetdb5.conf) # Listening for connection requests on mapi:monetdb://127.0.0.1:50000/ # MonetDB/SQL module v2.24.0 loaded

when i kill the monetdb daemon, my perl script is throwing this error : # ./monetdb2.pl Caught a SIGPIPE at /usr/local/share/perl/5.8.8/MonetDB/CLI/MapiPP.pm line 93 $ = eval {...} called from file `/usr/local/share/perl/5.8.8/MonetDB/CLI/MapiPP.pm' line 93 $ = MonetDB::CLI::MapiPP::Req::query('MonetDB::CLI::MapiPP::Req=HASH(0x83a66e0)', 'SELECT * FROM env') called from file `/usr/local/share/perl/5.8.8/DBD/monetdb.pm' line 567 $ = eval {...} called from file `/usr/local/share/perl/5.8.8/DBD/monetdb.pm' line 567 $ = DBD::monetdb::st::execute('DBI::st=HASH(0x83a683c)') called from file `./monetdb2.pl' line 8 Aborted

Also i can connect with no problem with mclient (no password required).

Please advise on how to get perl talking to monetdb5.

Thanks in advance, SB

[Monetdb-developers] Cannot get perl talking to monetdb5 nightly stableFrom: Rt Ibmer <rtibmx@ya...> - 2008-06-17 02:06 I am using the nightly stable build of monetdb5. All outside of perl->monetdb seems to be working just fine. I just can't get perl to talk to the db.

Here's what I did:

- installed from nightly stable source on Fedora 8

- copied the source from http://homepages.cwi.nl/~mk/MonetDB/The-Perl-Library.html into mytest.pl

- tried running: perl /tmp/mytest.pl

but it came back complaining about missing libs in @INC.

So then I added these steps:

- /var/tmp/MonetDB-1213632062/MonetDB-client/clients/src/perl - make install and also ran make instlal in the various subdirs like MonetDB-CLI and others (not sure if this step was necessar)

Then I tried running the script and this time it executed without the @INC errors. So this was progress.

However all I get is this: ------- Start a simple Monet MIL interaction

data sources: dbi:monetdb: --------

and then nothing. It just sits there indefinitely. In playing with the source of the .pl I see that it is the "my $dbh = DBI->connect( $dsn, ..." that execution stops at.

I have merovingian running and the db is started. I also tried with merovigan stopped and just using mserver5 --dbinit="include sql;" but I had the same result.

Am I doing something wrong? Thanks.
