RE: [Etherboot-developers] Why doesn't gas assemble start32.S

[Eno C. <Eno...@Mi...>]

My results are the same as yours with the exception I didn't get the
assembler messages but that is ok. 

I don't quite understand the implications here - too early on Monday morning
I guess. When I have digested this business, I'll post again.

Over the weekend, I did have an opportunity to look into assemblers. I am
startled to discover nasm, a product that clearly outperforms tasm and masm.

Thank you once again. I think you and Ken are doing the community a great
service.

Eno

Did you uncomment the AS86 define in Makefile (the first one)?  If you 
didn't you wouldn't recompile anything. Here is the relevant part of the 
Makefile:

# If you have not made any changes to the *.S files, AS86 need not be set.
# (most people)
# If you have made changes to the *.S files and you want to rebuild 
*loader.bin
# and {floppy,com}load.bin and you have as86 from the ELKS Dev86 package 
(not
# the one that normally comes with Linux) (not most people)
AS86=          as86
# If you have made changes to the *.S files and you want to rebuild 
*loader.bin
# and {floppy,com}load.bin and you have nasm (not most people)
#AS86=          nasm

if I do:

$ make clean

then

$ make bin32/start32.o

I get:

gcc -E -DMOTD -DIMAGE_MENU -DBACKOFF_LIMIT=7 -DASK_BOOT=3 
-DANS_DEFAULT=ANS_NETWORK -DTAGGED_IMAGE -DELF_IMAGE -O2 -g 
-fstrength-reduce -fomit-frame-pointer -m386 -malign-jumps=1 
-malign-loops=1 -malign-functions=1 -Wall -W -Wno-format -Wno-unused 
-DVERSION_MAJOR=4 -DVERSION_MINOR=7 -DVERSION=\"4.7.17\" -DRELOC=0x98000  
start32.S | as  -o bin32/start32.o
{standard input}: Assembler messages:
{standard input}:327: Warning: indirect ljmp without `*'

How about you?  

$ gcc --version
egcs-2.91.66

What version of gcc are you running?

I hope this helps,

Regards,

Marty
