Ciao

sto testando rails2.2, ho provato a creare una nuova applicazione ma  
quando lancio il comando “rake db:create” mi informa che devo installare  
con gem la libreria mysql non essendo piu integrata in rails, provo a  
installare la libreria e compare questo:

> 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  
> PS:mysql lo uso quotidianamente con php e funziona

Ciao,  
per installare la gemma mysql devi avere le librerie di sviluppo di  
mysql.  
installale  
così:  
sudo apt-get install libmysqlclient5-dev

poi riprova ad installare la gemma.

Grazie, ora funziona tutto  
PS:per chi avesse lo stesso problema su ubuntu il pacchetto da  
installare si chiama libmysqlclient_1_5-dev
