I think you want to only do this once.

You've got "section .text" and "section .data" swapped!!!

"_start" exists in the C "startup" code (crt0.o?), and we only want one
- this calls "main", so start your asm code with "main" nd has to be
declared global), not "_start". Or link with "ld -o myprog ns.o rand.o
-I/lib/ld-linux.so2 -lc".

Dunno about that one. I thought those were "standard"... shouldn't need
underscores... Dunno. Jeff Duntemann's got a "rand()" example in
linuxcode.zip from:

http://www.copperwood.com/pub/

I'm "working on" (figure of speech) a reply from a couple messages ago
with a few simple C/asm examples... I'll get back to ya "real soon now"...

(incidentally, to reply to this list, hit "reply all" - just "reply"
replies only to the sender - I'm not sure the message I refer to
actually made it to the list...)

I'll get back to ya - and see my post on the forum... might help...

Best,
Frank

a quick question:

2008-11-09T08:17:59Z

Hello,
I'm going to try to write a "guess the number." tyep program.
First, I wrote this, so I could link to it:
#include <cmath>
#include <ctime>
#include <cstdlib>
int rnum();
int rnum()
{
srand(time(NULL));
return (rand()%10);
}
I'm also going to have to write a rapper for itoa.
next, my asm program so far is as follows:
global _start
section .text
welcome db "Welcome to guess the number!",10,"Written by Tyler Littlefield
<tyler@...>",10,10
welcomelen equ $-welcome
texta db "I am thinking of a number between 1 and 10.",10,"Can you guess it
in three tries?",10
textalen equ $-texta
section .data
nop
_start:
nop
mov eax,4
mov ebx,1
mov ecx,welcome
mov edx,welcomelen
int 80h
mov eax,4
mov ebx,1
mov ecx,texta
mov edx,textalen
int 80h
when I compile with nasm, that works great. but when I gcc ns.o rand.o it
gives errors about _start, and then says it can't find time and srand and
rand.
Ideas?

Thanks,
Tyler Littlefield
