Notes:

In windows platform, you must use 
#gem install eventmachine --pre
Then `eventmachine (1.0.0.beta.4.1 x86-mingw32)` installed

Following does not work
#gem install eventmachine

Who knows why?

Download openssl

http://www.openssl.org/source/openssl-0.9.8l.tar.gz

Extract openssl

Copy the openssl tarball into the `c:\mingw` directory
#cd mingw
#tar zxf openssl-0.9.8l.tar.gz

Make openssl libraries

#cd mingw/openssl-0.9.8l

Platform support

Cool.io gem is the new release of Rev gem which is a ruby impelmentation of Libev, but not support Windows.

Performance

Cool.io performance is slow than EventMachine, cause of more functionality are implemented by ruby than in C.

I guess EventMachine is the best event-loop implementation in RUBY enviroment.

Error

When I install iobuffer, rev rubygems, following error prompted:

<internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- 
script/../config/boot (LoadError)
   from <internal:lib/rubygems/custom_require>:29:in `require'
   from script/server:2:in `<main>'

Steps

Download libev source in http://dist.schmorp.de/libev/
run >sh ./configure
run >make
libev.a static lib file generated in ./lib

Notes:

I remembered that I cannot compile it successfully before. But after I compiled the LibUV, and added the header file & libs, I can build libev successfully.

	------------
	1. IPV6 patch
	------------
	Add following definition code in win/winsock.h


	//
	// Options to use with [gs]etsockopt at the IPPROTO_IPV6 level.
	// These are specified in RFCs 3493 and 3542.
	// The values should be consistent with the IPv6 equivalents.

	It's simple, add https gem sources:

	# gem sources -a https://rubygems.org/
