Hi,

I have been using the SASM assembly language editor for a couple of days now and I've found a number of programs on the net to display a Hello World message. I have tried a number of these and none of them output anything at all. Below is an example of the code I've found :

.intel_syntax noprefix

.bss

.data

msg:
.asciz "Hello, world!\n\r"
.equ len, 15

.text

.global _start

_start:
push rbp
mov ebp,esp
mov edx,len
mov ecx,msg
mov ebx,1
mov eax,4
int 0x80
pop rbp
mov eax,1
int 0x80
.end

Another thing I want is to output all files, source, object files and so on to the same folder when assembling. How do I do this, because when the object file is assembled it outputs to the folder /tmp/SASM and not my folder ?

Thanks

FC.

here is a show me

Hello, world!


SASM: The Simple Assembler
Reference Manual

In care of google.

that is all I know about it , sorry

Hi,

After much hair pulling concerning this problem I thought I would try the NASM assembler instead of the GCC
assembler and the programs work, albeit with a little bit of tweaking. So I will continue using NASM when writing assembly language coding in Linux.

pls - mark solved. cheers!

For 64 bit, you might want syscall, instead of int 0x80.

You don't really need an OS, just <446 bytes in the boot sector

Now, that's what I'd enjoy doing

Writing Hello World Bootloader interesting.
