While installing iconv on windows I get the following errors
following the advice of a users post here I tried the following after installing libconv http://gnuwin32.sourceforge.net/packages/libiconv.htm

I had no success, below are the output errors.

I solved this issue by,
Error while installing iconv on windows by ruby2.0.0
Tricky part was copying files from /include, /bin and /lib of /GnuWin32 quickly into /Ruby2.2.0/lib/ruby/gems/2.2.0/gems/iconv-1.0.4/ext/iconv when gem install goes to Building native extensions. This could take a while...
Hope this will help someone.
