How to assemble/link with MASM32?

[sidezr]

I installed MASM32 editor, but I'm having a problem. Not even the simplest assembly program will assemble; not even the samples coming with MASM32.

I used the MASM 6.1 and the same program built without errors and worked (but under DOS).

Any help on how to configure the MASM32 editor or what to do so that it will work? I need a free good integrated ASM editor/builder/debugger that works under Windows 7 x64 for my Computer Science class. I thought MASM32 was what I needed. Any help, please?


I get this list of errors when I select "Project/Assemble ASM file":

Hi sidezr,

Check to see if the libraries built OK when you installed MASM32. 16 bit DOS code will not build with MASM32 as it uses a 32 bit PE linker but the examples should build Ok from the editor.

Show us the code that you tried to build that created the errors and we may be able to help you.

Well, the installation seemed to have been successfully.

Here is the program I tried to build; it does nothing specific but just some numeric operations. It was the class example. I really appreciate any help, thanks :-)

it assembles and links fine
what you have is 16-bit code and it requires use of a 16-bit linker
the assembler, however will handle it
i ran the program and got no output - i didn't look at the code
i'll have a look at it tomorrow

[sidezr]

Yes, this code produces no output, and I know it's mainly 16 bits. It's just a sample to try the assembler. It builds well on older MASM, but I get those errors I posted in my original post when trying to build from MASM32 editor.

How did you do it for the MASM32 to build this? Any settings or anything I should put?

[FORTRANS]

Hi,

   You need to assemble your file with ML and link it with the
16-bit linker LINK16 in the \MASM32\BIN directory.  The
commands will look something like the following when used
in a *.BAT file.

Regards,

Steve N.

Code Select Expand


Try this;

\MASM32\BIN\ML  /c /Fl /Fm %1.asm
\MASM32\BIN\LINK16 %1.obj;

or try;

\masm32\bin\ml /c %1.asm
\masm32\bin\link16 %1.obj;

use the following to see what the switches mean:

ML /?


[dedndave]

as Hutch said, i used both hands....
.... and a batch file like Steve said, too   :bg

i wrote a batch file that should help
download and unzip it, then place a16.bat into the masm32\bin folder
that folder should be in your PATH environment variable
then, at the prompt....

oh - and i attached the EXE if you want to play with it in debug
