asm source

[Manuel Bouyer]

Hello,
I need to write short binary for I/O control in assembler.
nasm -f hello.asm
ln -s -o hello hello.o

You mean ld, not ln here, right ? an object is not an executable, it
needs some more stuff linked in.

: In FreeBSD in first line in all sources asm codes is:
: %include 'system.inc'

There's no file named system.inc in FreeBSD, nor do any of the .S
files in FreeBSD have this file. Also %include is not found in any of
the sources.

Hello,
I need to write short binary for I/O control in assembler.

Remember that userland binaries run in ring 3 on i386.

nasm -f hello.asm
ln -s -o hello hello.o

ln?

Hi!

I wrote some examples to the wiki:
http://wiki.netbsd.se/NetBSD_Assembly

BTW, it shouldnt sigsegv on missing elf header, but apparently it does...

Can anyone write me what must by define in assembler source
for correct this problem on NetBSD platform?
Thanks Jan Vlk
