NASM wont work

Hey

I have been struggling for a while to get this thing working. I am running that basic "Hello World" script on page 36 of the study guide. NASM doesn't want to work. This is the error I get:

D:\UNISA\PROJECTS\2007\COS221>as hello

D:\UNISA\PROJECTS\2007\COS221>nasm -f bin hello.asm -o hello.com -l hello.lst

Any ideas? I'm running a core2. Could that be problematic?

Hi I tested out you program exactly as you've typed it using identical name and directory structure and it works fine. I have a 2200+ AMD I sugest you try isolating the problem by installing NASM on another core 2 computer. If it turns out that it does not run on core 2 then I'd suggest you install VMare Workstation on your computer and load it up with Windows 98. I tested NASM on a Windows98 Virtual Machine and it works perfect. One other thing is try put those folders on the C: instead of D: drive I dont have a D drive so i couldn't test that.

Are you running Linux or WindowsXP? and if XP, have you loaded sp2. What version of NASM do you use? There is no clear answer in the forums, except that it's difficult to determine the exact cause unless you debug NASM properly. Do you have your Windows firewall enabled when you run NASM?

I found nasmw.exe on the net. Nasm was giving me hassles too.

thanks for the replies.

tjvanaarde: dont have access to any other core2s, ill try my friends laptop

FerdieL: im on XP SP2. Just tried without my firewall, still doesnt work. NASM v0.98

Rick: kewl, ill have a look.

I just tried it on a different machine: AMD Athlon XP 2400+ with XPSP2. Same problem! I'm using the Nasm from the Unisa CD, surely there can't be a problem with that. I'll try nasmw...

downloaded that nasmw.exe and TADA! works perfect. Thanks anyway guys.

Hi guys!

I have the same problem trying to run NASM on my PC.

Where can I get nasmw.exe?

Anita
