FreePBX 2 has been tested with SuSe LES 9 and SuSe 10.

In reality seems fairly solid with not a lot of work needing to be
done to run FreePBX. Mainly check that you have DB (installable via
PEAR if required) and PHP4-GETTEXT (available as part of the SUSE
install) installed. If you have any PHP problems check that you have
the line include_path = ".:/usr/share/php" in /etc/php.ini. (The '.:' is the important bit)

To install DB, or if you aren't sure whether you have it installed, you can use pear. pear list will show a list of installed packages. To install DB either run pear install DB
on the command line or visit http://pear.php.net/package/DB and
download the latest stable version, 1.7.6 at present. A pear install
should download it and install it but it will complain about any
dependancies it needs and had a tendancy to fail on my system due for
this exact reason. The best way I found was to download the file onto
my SuSe? system and run pear install -n <location/filename>
manually. This tells pear to ignore any dependancies, as otherwise it
will probably complain about pear itself! Once finished you should have
DB.php and a DB directory in /usr/share/php.

When installing FreePBX remember that the webserver root is
different to the one defaulted to in the install_amp script. Your
webserver root should be /srv/www/htdocs so use that as the root and a
bit of common sense to change the panel and cgi-bin paths.

No other file changes should be required to get FreePBX working.
