Problems with ffi on windows 8 x64

First tried to use berkshelf gem, but it says

Then tried to reinstall ffi gem with different versions

gem uninstall ffi
gem install ffi -v 1.0.9

gem uninstall ffi
gem install ffi

It installs well, but something fails while installing documentation

gem uninstall ffi
gem install ffi

But no ffi installation has fix the main problem with berkshelf.

I had a similar problem for ruby version 1.9.3 ruby 1.9.3p551 and 64-bit linux as well. Install of libffi-dev was the first step, as in answer numbe 1.

gem uninstall ffi
gem install ffi

still had the same problem. Only after adding the install of rdoc gem:

gem install rdoc
gem uninstall ffi
gem install ffi

worked with no errors.

I had a similar problem installing another gem under 64-bit Linux. When compiling the gem I would get the exact same error regarding the ffi gem. My fix was to install libffi-dev package and it worked. There is an X86-64 for Windows/MingW version of this package so I would recommend making sure you have installed this.
