i was able to get it to work .... but sadly it's on nasm .. at first
i've tried using nasm, yasm, gas and it all came to that one
conclusion "Operation not Permitted" but i was able to get this
workaround code to label the file OpenBSD so that OpenBSD will run it
.. i dunno how this is exactly done .. (I'm still thinkering) but I'll
get there :) here's what i founded out
you can check the difference when you do a :
$ file hell
hell: ELF 32-bit LSB executable, Intel 80386, version 1, for OpenBSD,
statically linked, stripped
$ file hello
hello: ELF 32-bit LSB executable, Intel 80386, version 1, statically
linked, stripped
the first file "hell" has the id code (see below)
====================================================
section .note.openbsd.ident align=2
dd 8
dd 4
dd 1
db 'OpenBSD',0
dd 0
====================================================
to brand the file as OpenBSD
the 2nd one is the gas asm code i was working on .. i did some
checking on a simple C "hello world" code and found out this
$ gcc -o hellO hello.c
$ hellO
hello world
$ file hellO
hellO: ELF 32-bit LSB executable, Intel 80386, version 1, for OpenBSD,
dynamically linked (uses shared libs), not stripped
it seems that with assembly your always on your own =)
that solves it .. atleast for the mean time i can play around with
nasm .. and think of a way to make it work for gas
thanks for all the comments, support, etcetera :)
