cobalt raq3 php mysql

Hello! Has anyone succeded installing php4 on a cobalt raq3 server? I have the following problem: If I compile php with mysql included in php distribution, it can't connect to database. For example phpMyAdmin gives me this error(it seems that mysql_error() return nothing): Warning: MySQL Connection Failed: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111) in /home/sites/site17/web/phpMyAdmin/lib.inc.php on line 255 Error MySQL said: Back If I compile it with option with-mysql=/usr the apache server don't start(gives a lot of SEGV). I use mysql-3.23.33, installed from rpms from www.mysql.com. Otherwise mysql works very good(ie from command line). thanks for any help, mache
