I used ruby-1.8.7-p249-i386-mingw32.7z on the windows 7 x64, and have
installed the devkit. But it failed to build the native extension of
eventmachine with error message as follow:
H:\study\fybjy\myoa>gem install eventmachine
Building native extensions. This could take a while…
ERROR: Error installing eventmachine:
