Newbie Segmentation fault question.

[manjaba]

Not sure why I'm getting the Segmentation fault statement on this program which runs ok:

#HelloWorld.s my second assembly program

.data

HelloWorldString: #label
.ascii"Hello World\n"

.text

.globl _start

_start:
#load all the arguments for write()

movl $4, %eax
movl $1, %ebx
movl $HelloWorldString, %ecx
movl $12, %edx
int $0x80

Thanks

Hmmm, there should be some code to terminate the program after you print out "Hello World".

You are not terminating your program correctly.

You need something like the following at the end.


movl $1, %eax ;; syscall 1 is exit()
movl $0, %ebx ;; argument to exit
int $0x80 ;; do it
