You shouldn’t have to build it if you’re using the one-click  
installer. It should install the binary gem.

gem install win32-api

First, I think you need to upgrade your rubygems library. Run “gem  
update --system”. If that should fail, grab the source from  
[http://www.rubyforge.org/projects/rubygems](http://www.rubyforge.org/projects/rubygems) and install manually.

Next, make sure your RUBYOPT environment variable is set. Or, if you  
prefer, explicitly require ‘rubygems’ first before attempting to require  
‘win32/api’.

Regards,

Dan

I have done this,

Select which gem to install for your platform (i386-mswin32)

1. win32-api 1.4.5 (ruby)
2. win32-api 1.4.5 (x86-mswin32-60)
3. win32-api 1.4.4 (x86-mswin32-60)
4. win32-api 1.4.4 (ruby)

> Installing RDoc documentation for win32-api-1.4.5-x86-mswin32-60…

that one gives me no errors but when i run my script that requires  
win32/api.rb

require ‘win32/api’  
no such file or directory…
