I just got a MASM compiler and I finaly figured out how to make .obj files. I can't figure out how to make .coms or .exes directly. Can MASM32 make program files? How? If not, is there any way I can convert .obj files to .com or .exe files? Thanks!
You need a linker (LINK.EXE, for example). Look in your masm distro, there should be one.
Thanks! but I have one problem. Every time I try to assemble this peice of code...
Code:
.MODEL medium
.386
.STACK 100h
.CODE
mov ax,13h
int 10h
mov ax,4Ch
int 21h
END
...it makes the obj file but it doesn't link. It gives me this error...

test2.obj : warning LNK4078: multiple ".data" sections found with different attr

Link error
Press any key to continue . . .
The error message says there are "multiple ".data" sections found with different attributes" but I don't have a ".data" statement in my code. How do I fix this?
I don't know if this is the same problem, but I think you need to specify the entry point, like so:
Code:
.MODEL medium
.386
.STACK 100h
.CODE
start:
mov ax,13h
int 10h
mov ax,4Ch
int 21h
END start
Also, that assembler looks like a DOS program, but the error message is as if you're trying to link it as a Windows exe...
In MASM there is a switch / that specifies you want to link after assemble. I primarily use TASM so I don't know the switch.
Try MASM /?
Reading the documentation would also come handy
