[Koha] Browse by hierarchy - Links not working

[Manos PETRIDIS]

Thank you Mark for the warning and suggestions. The truth is I've had some unix experience in the distant past; instead of copying anything, I'd link so that I could easily revert to the original state.

As I've mentioned before, I use a ready-made VM, the reason that I don't ask the provider of that image directly is that his (and your) replies will be available to us all, for all current and future users of his appliance.

/etc/environment is empty in my installation, I've updated /home/koha/.bashrc instead, as per Ian's instructions.

Kind regards,
Manos

P.S. I do miss the good old unix days when all I had to check was a .profile

Greetings,

DISCLAIMER: THIS FEEDBACK DOES NOT APPLY TO EVERYONE, PLEASE DON'T JUST TRY THIS BECAUSE YOU HAVE A PROBLEM.

This is the WRONG solution. Yes, it works, but upgrading your koha in the future becomes a nightmare!

There are supposed to be two environment variables defined:
$KOHA_CONF
$PERL5LIB
If you do not have these defined, you will encounter problems running Koha scripts.

(WARNING! WARNING! WARNING! I AM NOT RESPONSIBLE IF YOU DO NOT READING
CAREFULLY.)
*IF* (IF, IF, IF, IF, IF) PERL5LIB is not (I repeat NOT, NOT, NOT, NOT) defined at all, and given the results of your search:
(DO NOT DO THIS IF PERL5LIB IS DEFINED, BECAUSE YOU COULD BREAK SOMETHING
ELSE!)
$ export PERL5LIB=/home/koha/kohaclone

Follow up questions:
If you have a kohaclone directory, how did you answer the build questions?
If you didn't build this, and it is a virtual machine image, ask the provider of that image.

One potential workaround, if your system is a koha only system:
Under Ubuntu, and perhaps other debian-based OSes (though I haven't tested
them) you can add to the bottom of /etc/environment (as root):
PERL5LIB=/home/koha/kohaclone
Log out, and log back in, and this will be set for EVERY user on the system. 
This is only a good solution if the system is a koha only system. Otherwise, you will need to modify appropriate rc shell scripts in particular users home directories to set it.

GPML,
