Cacti and egroupware coexistence

[el_es]

Hello,
I have posted this question on Ubuntu Forums and Cacti support too.

I have the cacti package :

cacti 0.8.7b-2ubuntu1

and egroupware 1.2.107-2.dfsg-2ubuntu1
(both from ubuntu repositories) installed on one machine.
While the egroupware works flawless, this is what is displayed when I try to login or navigate over Cacti :

Warning: mb_ereg_replace() [function.mb-ereg-replace]: mbregex compile err: premature end of char-class in /usr/share/cacti/site/include/global.php on line 86

Fatal error: Call to undefined function db_connect_real() in /usr/share/cacti/site/include/global.php on line 191 

This started immediately after egroupware has been installed; I am literate enough to know this must be somehow php related; But I post this here to gather as many pointers as possible to solve this problem.

Any pointers to where to start looking are appreciated.

This is what apache writes to error.log :

The relevant line in /usr/share/egroupware/phpgwapi/inc/class.html.inc.php : line 117 is function tooltip :

        {

                        $this->wz_tooltip_included = True;
                }
  </pre>
<p>Any pointers ?</p>

Any pointers ?

i’ve had problems running cacti and egw on the same apache instance as cacti
cannot use the php mb overload (php_value mbstring.func_overload 7) functions
(or it fails).

setting php_value mbstring.func_overload per directory, or even per virtual
host seems to have no effect as one is never sure which instance of apache an
incoming request will be handled on (using the prefork model --the default in
fedora).

i’ve had to change my egw to php_value mbstring.func_overload 0, rather, i
commented it out for now.

Thanks Anthony, that did it !

For the record : (under Ubuntu)
setting /etc/apache2/conf.d/egroupware line 29 to

php_value mbstring.func_overload 0

(previously php_value mbstring.func_overload 7)

made it work.

Thanks a lot,
Lukasz

Don’t know if this is relevant, but as Egroupware uses php5 (and php5 is installed) I thought the /etc/apache2/conf.d/cacti.conf now reads

Alias /cacti /usr/share/cacti/site

<DirectoryMatch /usr/share/cacti/site>
Options +FollowSymLinks
AllowOverride None
order allow,deny
allow from all

            AddType application/x-httpd-php .php

            php_flag magic_quotes_gpc Off
            php_flag short_open_tag On
            php_flag register_globals Off
            php_flag register_argc_argv On
            php_flag track_vars On
            # this setting is necessary for some locales
            php_value mbstring.func_overload 0
            php_value include_path .

            DirectoryIndex index.php

[/quote]

that is, the IfModule lines are commented out. Dunno if this is relevant, (didn’t want to experiment too much ;).

i’m not sure if it would make a difference. i use php 5 and have had trouble
with defining the php_value mbstring.func_overload value in apache as
egroupware would work and cacti would not, regardless of which directory
header or virtualhost header i tried.
