Why is Rake aborting because of “Bad file Descriptor”?

Question

I have a problem creating a database using rake db:create .

I followed the " Fat Free CRM Guides: Installation on Microsoft Windows " guide to install the Fat Free CRM on Windows.

I am on 32-bit Windows 7. Rake is 0.8.7. RubyGems is 2.0.3 and Ruby is 1.9.3. I am using MySQL2 v0.2.6.

The error I got was:

C:\RailsInstaller\fat_free_crm>rake db:create RAILS_ENV=production --trace
** Invoke db:create (first_time)
** Invoke db:load_config (first_time)
** Execute db:load_config
** Invoke rails_env (first_time)
** Execute rails_env
** Execute db:create
rake aborted!
Bad file descriptor

C:\RailsInstaller\fat_free_crm>[/code]

I changed libmysql.dll for win7 - 32bit

The configuration of database.yml is:

development: 
adapter: mysql2
encoding: utf8
database: fat_free_crm_development
pool: 5
username: root
password: ale
#socket: /var/run/mysqld/mysqld.sock
host: localhost
#host: 127.0.0.1
port: 3306

test:
#<<: *development
database: fat_free_crm_test

production:
#<<: *development
adapter: mysql2
encoding: utf8
#database: crm_production
database: fat_free_crm_production
pool: 5
username: root
password: ale
#socket: /tmp/mysql.sock
#host: 127.0.0.1
host: localhost
port: 3306

staging:
#<<: *development
database: fat_free_crm_staging

Does anyone have any ideas?

At lines 9, 25, 29, 43 remove &development and <<*development . I think you have syntax errors in your database.yml file.
