Well I got
[EMAIL PROTECTED] tmp]$ cc -c asm_test.c
asm_test.c:2:9: warning: multi-line string literals are deprecated
asm_test.c: In function `main':
asm_test.c:1: warning: return type of `main' is not `int'
/tmp/ccZR2pQa.s: Assembler messages:
/tmp/ccZR2pQa.s:14: Error: no such instruction: `move $0x0,%ebx'
/tmp/ccZR2pQa.s:15: Error: no such instruction: `move $0x1,%eax'
so changing 'move' to mov got rid of the assembler warnings
void main() {
__asm__("
mov $0x0, %ebx
mov $0x1, %eax
int $0x80
");
}
