Sorry for the double post. Trial and error: I installed phpbb 3 and the wordpress to the same db and used the same prefix phpbb_.
I received the following errors:
WordPress database error: [Incorrect table definition; there can be only one auto column and it must be defined as a key]
ALTER TABLE phpbb_posts ADD COLUMN ID bigint(20) unsigned NOT NULL auto_increment
WordPress database error: [Key column 'ID' doesn't exist in table]
ALTER TABLE phpbb_posts ADD PRIMARY KEY (ID)
WordPress database error: [Key column 'ID' doesn't exist in table]
ALTER TABLE phpbb_posts ADD KEY type_status_date (post_type,post_status,post_date,ID)
WordPress database error: [Incorrect table definition; there can be only one auto column and it must be defined as a key]
ALTER TABLE phpbb_users ADD COLUMN ID bigint(20) unsigned NOT NULL auto_increment
WordPress database error: [Key column 'ID' doesn't exist in table]
ALTER TABLE phpbb_users ADD PRIMARY KEY (ID)
WordPress database error: [Unknown column 'ID' in 'where clause']

Success!
Then I received an error after logging in:
Fatal error: Cannot access empty property in /home/content/d/e/a/deathstryk3/html/CCF/blog/wp-includes/user.php on line 305
I am not sure what to do
