Run Ruby, Gems, Rails, MySQL and RMagick on Cygwin

Before using cygwin, I did not expect that the commands of rails do not work in cygwin. To make ruby, gems and rails to work, there are some additional tasks to do as following:

• Add devel -> make + ruby + gcc + subversion modules from cygwin installation
• Download gems tgz install package from Ruby Gems download home
• tar xzvf rubygems-1.0.x.tgz
• cd rubygems-1.0.x
• unset RUBYOPT (before install gems, clear RUBYOPT=rubygems)
• ruby setup.rb
• gem install rails --include-dependencies
• Download mysql source tar.gz file from MySQL download page
• tar xzvf mysql-5.0.45.tar.gz
• cd mysql-5.0.45
• ./configure
• make install ( or to do it faster, just make install under sub directories libmysql and include.
• gem install mysql
• Change the database server from localhost to 127.0.0.1 in the database.yml of your rails app
• Install ImageMagick, libmagick-devel, XFree86-lib-compat, xorg-x11-devel, libbz2-devel module from cygwin installation file
• gem install RMagick
  
• ruby script/server. voila!
