I installed Cygwin 1.7. I've had a problem with Windows Vista and Cygwin 1.5 and was hoping the new Cygwin would correct the problem. I get the following error when I try to run some software that was developed in house and that uses gcc. fatal error - MapViewOfFileEx Win32 error 487. FYI - I can email more info. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
