Re: Building libffi with MSVC

[Nathan Rajlich <nathan at tootallnate dot net>]

Yes those instructions at the top are for a Unix system. For Windows,
try something like this:

  $ svn co http://gyp.googlecode.com/svn/trunk gyp
  $ gyp\gyp.bat -f msvs -G msvs_version=2010 --depth=. libffi.gyp
  $ msbuild libffi.sln
  $ Debug\test.exe

Cheers!
