quando cerco di installare mysql2 mi dice quanto sotto riportato:

perchè? come se non trovasse qualcosa, ma cosa?
aggiungo che in /var/run/mysqld/ c’è mysqld.sock
il sistema ora è ubuntu server

Quando ho avuto questo problema in passato, era riconducibile al fatto
che l’installazione della gemma non trovasse l’eseguibile del client
mysql.
Prova a mettere la directory cos:

gem install mysql --with-mysql-dir /path/to/mysql

Potrebbe essere necessario installare libmysqlclient-dev.
( un virtual package, quando farei apt-get install ti dir lui il
pacchetto da installare).

Ciao ciao

Ok, Paolo vince. Ma oltre a eseguire meramente il comando indicato, sai
dirmi a cosa serviva quel pacchetto?

Certo. In generale, quando installi un pacchetto su unix vengono
installate anche le librerie che servono per farlo funzionare. Ad
esempio, apt-get install mysql installer tutte le librerie per far
funzionare i binari di mysql.

Se per tu devi compilare un programma che usa funzionalit in quelle
librerie hai bisogno di pezzi in pi, i pacchetti che solitamente
hanno -dev nel nome.

Lo si fa per installare sulla linux box solo le cose che effettivamente
servono.

sono gli headers necessari a compilare alcune parti binarie (quindi
codice
nativo in C, non ruby) della gemma mysql2

può capitare con diverse gemme (penso a nokogiri o mongo, per esempio).
in quel
caso, controllo l’output di errore, vedi qualche libreria/header è
mancante, e
cercala con apt-cache o aptitude. di norma, dopo un po’ di tentativi,
funziona
