MASM in ubuntu

[manuganji]

I need an equivalent of MASM (Macro Assembler) in windows for ubuntu . Just MASM not TASM,NASM or something else. Please help me with this. I need it for one of my courses. I really don't want to install windows again for this. Thanks a lot in advance.

If you just want to use it for academic purposes i guess it would work under Wine: http://winehq.org. I've read something about violating the MASM EULA when developing on Open Source Software, haven't read it myself though. But you should take that under consideration.

If Wine doesn't do the trick you may install Windows in a Virtual Machine using VMware Server: http://www.vmware.com/products/server/

Hope this will help!

NASM is in the repos.

You have to..
Use a vm like VirtualBox.

I don't know what you are exactly trying to do with MASM, but since MASM
was DOS based why can't you use DOSBOX, and run MASM from DOSBOX. It would
be the same as using an old DOS based box. DOS box should be in the repos.

It would be worth a try.

You might consider A86 (Assembler) and D86 (Dis-assembler) while you are
playing with MASM. They used to be very good programs. I did use them
years ago, but have forgotten most of that now.

If you can't locate A86 or D86 PM me as I have them somewhere, on an old DOS drive.

Also, a search of this forum talks about DOSBOX-FE a Front End for DOSBOX.
It might be worth trying.

Seems to be an issue with keymapping:

Search forum for dosbox for more details.

Good Luck.

Yes, MASM51 works fine in the DosBox window. I couldn't find a
copy of one of my old assembler programs, but I did try
to use MASM. WOW! It has been years, since I did that kind
of work. But it is FAST, COMPACT, and works good if you code
it correctly. I prefered using TASM because of the TDEBUGGER
that was out. It was NICE! Symbolic Debugger by Borland Intl.

Anyway, just go to your /home/login directory, create a dosprog
subdirectory and you will be all set. I made another for MASM
at /home/login/dosprog/masm51

I also changed the permissions for both to login:login versus root.
Then in DosBox you follow the screen prompts. (Note: If you open
DosBox before you create the MASM51 subdirectory you will have to exit
and start DosBox again so it finds the subdirectories.)

You should be in good shape for your class! Wish I was going.......

(I wrote a small asm program to turn the NUMLOCK key off in 7 bytes.
Another guy wrote it in "C" and it was 32K. He was impressed.)

I'd like to thank all those who have responded so far. BTW.... Can you please give me solutions which DON'T require me to use WINE or VMware. Is there no other clean and promising method?? And.. lkraemer how could you do that in seven bytes ?!!!!!!

[pg-13(prostitute)]

i use amd chips so im fond of at&t syntax

seems wrong to use intel

[lkraemer]

manuganji,
Well, after searching some old backup CD's I found the numlock.com
program......and I was wrong......it was 8 bytes not 7. I won't be
able to get to my source for another 3 weeks. I'll send it to you
to view when I find it.

In the mean time, I wrote another program that logged each powerup
of a friends work computer so he could tell what time, and how many
times it had been powered up while he was gone. He disguised it as
a video driver being loaded.

As you can tell I used tasm versus MASM, but they worked the same.

Now you can play.

Documentation:

  
                           LOGPWRUP


PURPOSE:     LOGPWRUP will save the DATE and TIME of system power up
             in a text file that is specified from the command line.
             This file can be placed anywhere on your hard disk as
             long as the specified path exists.

LOADING:     Run LOGPWRUP from within your AUTOEXEC.BAT file to store
             SYSTEM RESETS or POWER UP conditions.

             LOGPWRUP C:\PATHA\PATHB\PATHC\POWERUP.LOG

             DATE and TIME will be saved to Drive C, PathA,
             PathB, PATHC in POWERUP.LOG

             If you want to get sneaky and try to disguise what this
             program is doing just rename the LOGPWRUP.EXE file to
             SETVIDEO.COM and use the following command within your
             AUTOEXEC.BAT file.

             SETVIDEO C:\PATHA\PATHB\PATHC\EGA.DRV

             Most folks will assume that an EGA Driver is being loaded
             by not knowing what the program really does.

             NOTE:  LOGPWRUP will not create any subdirectories on
                    your drive, so they must exist when the program
                    is executed.  It will not log any WARM BOOTS, but
                    can be easily modified to log these if they are
                    needed.
