Hi all,

I wanted to test thin at work, on Windows with VC++ 2005, but I can’t  
install it because I got an error with the  
compilation of em.cpp, because EINTR was not included in the  
“project.h”.

I would like to test thin and use it, but with this bug, I can’t install  
it :-).

I can compile EventMachine with ruby ext\extconf.rb and run the  
makefile. But how can I generate the gem, because I  
didn’t find the gemspec file.

Best Regards,

Stephane

hey Stephane,

EventMachine 0.8.1 comes w/ precompiled binaries for windows.  
Try installing latest version of Thin, it should work.
