Ciao a tutti,  
ho aggiornato il sistema a openSuse 11, ma qui non c’è il package  
mysql-devel (!!!) e quando lancio gem install mysql da errore  
c’è un modo per ovviare senza downgradare alla 10.2 ?? (neanche sulla  
10.3 credo che ci sia )

Grazie

Ciao ,

si quella l’ho installata, ma mi continua a dare errore … penso sia  
perché vuole le librerie lato server; in Yast la descrizione di quel  
pacchetto  
è:  
“This package contains the development header files and libraries  
necessary to develop MySQL client applications.”

Ti dirò di più, ho anche installato le mysql-devel ma per la OpenSuse  
10.X (sono le uniche disponibili) e le ha prese… cioè non ha dato  
errore… ma quando faccio

gem install mysql  
Building native extensions. This could take a while…  
ERROR: Error installing mysql:  
ERROR: Failed to build gem native extension.

/usr/bin/ruby extconf.rb install mysql

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.

Con la 10.2 mi sembra avessi risolto proprio installando mysql-devel  
appropriate: entro questa mattina devo decidere se  
downgradare… help !!!

Purtroppo ho trovato esempi solo con il client, anche qua

Forse tra gli rpm sul sito mysql  
[http://dev.mysql.com/downloads/mysql/5.0.html#downloads](http://dev.mysql.com/downloads/mysql/5.0.html#downloads) trovi quello che  
ti serve, ma non posso esserne sicuro perché uso tutt’altra  
distribuzione e probabilmente non ho neppure installato qualcosa per  
aprire gli rpm e vedere cosa contengono.

Ciao,  
solo per aggiornarvi: alla fine mi connetto al db, ma non so bene come e  
perché;gem install mysql continua a fallire e quindi non è installato;  
ho installato ruby-mysql da package manager:

ruby-mysql - MySQL bindings for Ruby

This is the MySQL API module for Ruby. It provides the same functions  
for Ruby programs that the MySQL C API provides for C programs.

Forse è questo che fa andare tutto ? Si può usare al posto della gemma  
mysql ?

Saluti

Luigi
