Hi,thank you very much for your help! I am waiting. Yes Mysql is running. And can you tell me anything more? I don’t understand ruby and rail. But I have to use openseradmin. ☹ Thanks! ---

it’s really a pretty general server - error ; something is wrong with the app, or the db, because the connection between the two isn’t working. it could be a couple of things, but my first guess is a prob with the mysql - did you set up the openseradmin database in mysql? set up a user to access the db? set the correct permissions in the database.yml file? i don’t know if you did your setup according to this link but in case you haven’t: [http://openseradmin.sourceforge.net/docs.php](http://openseradmin.sourceforge.net/docs.php) …anyway, i’d check the db to see if there are any problems. basically what you should be having is this: \*) the app \*) the correct permissions to access the db (RAILS\_ROOT/config/database.yml) ``` # btw, RAILS_ROOT is a constant that stores the path to your app # on your system - it is basically a string that is: # /path/to/your/app/ ``` \*) mysql \*) the db exists hope some of the above helps ---

Hi, thank you very much!! I think there’s something wrong with mysql too. Because I have to do: gem install mysql before intalling openseradmin. And then I have ruby extconf.rb install mysql checking for mysql\_query() in -lmysqlclient… no checking for main() in -lm… yes checking for mysql\_query() in -lmysqlclient… no checking for main() in -lz… yes checking for mysql\_query() in -lmysqlclient… no checking for main() in -lsocket… no checking for mysql\_query() in -lmysqlclient… no checking for main() in -lnsl… yes checking for mysql\_query() in -lmysqlclient… no \*\*\* extconf.rb failed \*\*\* Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options.
