"uname -a" should make that clear. You'll need to instal a 64-bit version if that's what you want. 2) Cygwin doesn't build Linux apps. If you have a cross-compiler then it won't automatically decide to build 64-bit Linux apps because you are on a 64-bit sytem. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
