“gem install mysql” failed. This might be another stupid question, but  
really block me for couple of days.

I tried gem:  
gem install mysql – --with-mysql-config=/usr/bin/mysql\_config

and got:  
ERROR: Error installing mysql:  
ERROR: Failed to build gem native extension.

```
/usr/local/bin/ruby extconf.rb

```

–with-mysql-config=/usr/bin/mysql\_config  
extconf.rb:1: command not found: /usr/bin/mysql\_config --cflags  
\*\*\* extconf.rb failed \*\*\*

This might be something wrong with mysql becouse ‘mysql\_config’ can not  
be located.  
[root@localhost ~]# whereis mysql\_config  
mysql\_config:

I also tried mysql-ruby:  
[root@localhost mysql-ruby-2.8.1]# ruby extconf.rb  
–with-mysql-dir=/usr/bin/mysql  
checking for mysql\_query() in -lmysqlclient… no

here is the env info:

```
[root@localhost ~]# whereis mysql
mysql: /usr/bin/mysql /usr/local/lib/mysql /usr/share/mysql

```

/usr/share/man/man1/mysql.1.gz  
[root@localhost ~]# ruby -v  
ruby 1.8.6 (2008-03-03 patchlevel 114) [i686-linux]  
[root@localhost ~]# rails -v

[root@localhost ~]# gem -v  
1.3.5

any suggestion will be appreciate 🙂

Indeed, you are missing the MySQL client and (probably) development  
files. You should install them using your package manager and try again.
