The code below assigns an integer number 20 to %ebx, which can be CORRECTLY assembled on both cygwin and CentOS, ###code begin### .section .data items: .long=A0 20 .section .text .globl _start _start: =A0 movl $0,%edi =A0 movl items(,%edi,4),%eax =A0 movl %eax,%ebx =A0 movl $1,%eax =A0 int $0x80 ###code end### However, when I wanted to get the number(20) by the following way, I found the difference between cygwin and CentOS, cygwin: ------------------------------ Matt AT Matt-PC ~ $ ./max2 Matt AT Matt-PC ~ $ echo $? 127 # The result is WRONG ------------------------------ CentOS: ------------------------------ [Matt AT localhost]# ./max2 [Matt AT localhost]# echo $? 20 # The result is RIGHT ------------------------------ Could someone give me a hand?thanks -- 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
