Using NASM / Re: How to build NASM / NDISASM?

« Last post by Frank Kotler on February 14, 2019, 10:07:06 PM »

Hi Ruud,

I don't think I can help you with this. I know little of the build process and nothing of OpenWatcom. I just do "./configure" and "make install everything". The developer's list might be able to help you.

I might be able to suggest another alternative. I'm quite fond of Agner Fog's "objconv" as a disassembler. Look around agner.org for it...

Best,
Frank

Is there a mirror somewhere for the nasm compiler or manual? It's kind of annoying trying to figure stuff out without access to it.

Edit: site is back up. Many thanks to Frank, Cyrill and Hans who responded to my query; going to take this opportunity to download the offline documentation now just in case...

Using NASM / How to build NASM / NDISASM?

« Last post by RuudB on February 14, 2019, 06:03:28 PM »

Quite some time ago I wrote my own disassembler for the 8088. I expanded it to the 80286 but that job isn't finished yet. I now also need one for the 80386. I can do two things: 1) expand my disassembler again or 2) use NDISASM. But NDISASM lacks some nice features my disassembler has. One thing I could do is add these features to NDISAM.
I tried building the original sources using Openwatcom. IIRC when installing Openwatcom it asked if it coud add itself to the PATH. I refused I don't like it if every program adds itself to the path. So before starting "wmake ...." I added the root directory and binnt to the path using a BAT file. But I still get errors: it cannot find various .h files like "assert.h", to be found in ...\openwatcom\h. I added this directory to the path as well, knowing that it most probably would not help, and unfortunately I was right.

The question: what did I forget / what did I wrong / am I missing something?

I hope somebody can help me. Thank you very much in advance!

The volunteers who maintain the site are probably busy. Most don't check in every day.

Programming with NASM / Re: I have a problem with a simple 64bit programm

Also, this is wrong:

Code: [Select]

  mov  rdi, rsi; argument
  call atoi wrt ..plt
The 2nd argument of main() is a pointer to an array of pointers. The correct reference is:

Code: [Select]

  mov rdi,[rsi+8]
And atoi() isn't a libc function, but a macro for strtol().

Okay. That's a surprise to me - I didn't know there were bugs of that sort in that version. We live and learn! Glad you got it working!

Best,

Hallo Frank,

I just upgraded to 2.14.02 and that one works fine. So it was indeed the version.
Thank you!

Kind regards, Ruud Baltissen

I am simply unable to duplicate this error. I'm using nasm-2.14.03rc2 - just upgraded to the latest version.

It looks to me like what you'd get if your editor were not producing ascii text. That's not only my best guess, it's my only guess... Wish I could help you more!

Best,
Frank
