HELP: assembly & C linking woes....

[Andrew Wan]

I am having problems linking an assembly object with my C object
files. Am getting:

Linker Warning: DOSSEG directive ignored in module asm.asm
Linker Error: Undefined symbol _ASMClsV in module main.c
Linker Error: Undefined symbol VADDR in module asm.asm

In my asm.asm file I've got:

DOSSEG
..MODEL huge
..386

..DATA
EXTRN vaddr : word;

..CODE
PUBLIC ASMClsV

ASMClsV PROC Near
;bla bla
ASMClsV EndP

In main.c I've got:

extern void ASMClsV();

Am trying to link using Borland C++ 4.5 since my source files are all
16-bit. I successfully linked the same asm.asm file with a 16-bit
pascal object using Turbo Pascal 7.0. Why can't I link using Borland C+
+ 4.5 to a 16-bit C file?

Also, I used Microsoft Macro Assembler 5. Should I use Turbo Assembler?

MAYBE the problem is the missing underscores in the asm
program

In my asm.asm file I've got:

EXTRN _vaddr : word;

add a leading underscore

Shouldn't that be
PUBLIC _ASMClsV

with the leading _
