Re: How to install a development environment? -- Debian 'etch'

[Davi Leal]

Both, the production system at gnuherds.org and my development environment are 
using the Debian 'etch' distribution.


GNU Herds transform the photo or logo of it users
=================================================

The transform-photo-or-logo feature is known to do _not_ work if you use 
Ubuntu 'gutsy' or 'hardy' as your webapp server, due such distributions ship 
a too new php5-imagick package:

The GNU Herds source code is using an old but stable version of such library. 
The one shipped with Debian 'etch':

  php5-imagick   0.9.11+1-4.1   ImageMagick module for php5


Ubuntu 'gutsy' was shipped with an unstable version of such library "Alpha 2".

  php5-imagick   2.0.0a2-1      ImageMagick module for php5

  Note 'a2' reference to "Alpha 2".

The API of such new library version has changed, so the image-transform 
feature of the GNU Herds webapp will not work too if you install it on a 
Ubuntu 'hardy' server.


I propose we follow using the Debian stable versions on our servers.

See the attached the files.

Copy them as follows:
 cp block.t.php /usr/share/php/smarty/libs/plugins/block.t.php
 cp modifier.dgettext.php /usr/share/php/smarty/libs/plugins/

Please, use a Debian 'etch' machine. If you are using another GNU/Linux 
distribution, and you do not want replace it, you could just install 
Debian 'etch' on a Virtual machine.

Note the step 9 at the "how to" guide [1]

    chown user templates_c   # where the user is from your httpd.conf
    chgrp group templates_c  # where the group is from your httpd.conf
