Using old fashioned bbPress 1.x from BuddyPress installation

[slaFFik]

After installation (see #6703) I tried to go to a page of that forums.

I got several PHP Deprecated and Strict Standards messages. But they are exist because bbPress is very old.
More importantly that I got these errors:

Notice: Use of undefined constant BBDB_USER - assumed 'BBDB_USER' in W:\OpenServer\domains\bp\trunk\wp-content\plugins\buddypress\build\bp-forums\bp-forums-bbpress-sa.php on line 59
Notice: Use of undefined constant BBDB_PASSWORD - assumed 'BBDB_PASSWORD' in W:\OpenServer\domains\bp\trunk\wp-content\plugins\buddypress\build\bp-forums\bp-forums-bbpress-sa.php on line 59
Notice: Use of undefined constant BBDB_NAME - assumed 'BBDB_NAME' in W:\OpenServer\domains\bp\trunk\wp-content\plugins\buddypress\build\bp-forums\bp-forums-bbpress-sa.php on line 59
Notice: Use of undefined constant BBDB_HOST - assumed 'BBDB_HOST' in W:\OpenServer\domains\bp\trunk\wp-content\plugins\buddypress\build\bp-forums\bp-forums-bbpress-sa.php on line 59

Because of that I wasn't able to connect to DB and see the page content.

Legacy forum seems to be installed correctly (Installed) Forums for Groups, path to bb-config.php is saved and correct. Though no extra bbPress table in the DB.

Latest trunk BuddyPress, 2015 theme, xdebug activated.

Single group Forums page (like this: http://trunk.bp/groups/sherlock-holmes/forum/) returns the same errors

These constants are meant to be set in the bb-config.php that BuddyPress tries to auto-generate (see bp_forums_bbpress_install). Can you check your file to see if they are in there?

No, see #6703. That was what BuddyPress said me to put in bb-config.php

Let's close this in favour of #6703 which contains the root issue.
