Question

so I have a big problem i want to start on a project using rails 2.3.11 and ruby 1.8.7 firs i installed my sql

    gem install mysql

then i run

    rake db:create

but i got an error

    Couldn't create database for {"adapter"=>"mysql", "database"=>"test_development", "encoding"=>"utf8", "reconnect"=>false, "username"=>"root", "pool"=>5, "host"=>"localhost", "password"=>nil}, charset: utf8, collation: utf8_unicode_ci (if you set the charset manually, make sure you have a matching collation)

after some search i fount a solution was given that to run these commands i uninstall mysql and run this lines

    *** 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.

    Provided configuration options:
--with-opt-dir
--without-opt-dir
--with-opt-include
