[CWB] Base class package "CWB::CEQL" is empty -- but it's there...

[Hardie, Andrew]

Hi Piotr,

Yes, it does look like perl is finding the module in your @INC - but, critically, the httpd's @INC must not contain the relevant path. This is unsurprising given that it looks to be somewhere in your username's home tree. (Assuming you're using Apache, it usually runs under the username www-data on Ubuntu). 

Setting $perl_extra_directories as you suggest should do the job.

best

Andrew.

Hi again.

I can do

     perl -e 'use base CWB::CEQL;'

from the commandline, and it seems all good -- I take it that perl is 
able to find the module in my @INC (?).

But apparently, when the cqpwebCEQL.pm tries the same, it fails, and so 
I can only use CQP for querying, because when I try CEQL, I get the 
"Base class package "CWB::CEQL" is empty" message.

My last Perl programming experience was sadly 20+ years ago, so I can 
only make naive guesses: am I looking at some permissions issue, or 
should I just add

$perl_extra_directories ='/home/piotr/perl5/lib/perl5/CWB'

to my CQPweb config, please?

I'm a bit surprised at potentially having to add this extra option, 
because all the installation of Perl modules (except for those 3 failed 
tests mentioned in my previous e-mail) went very smoothly, and my system 
is a fairly run-of-the-mill kubuntu 16.04, running Perl v5.22.1.

Thanks and best,

   Piotr
