Re-posting... Sorry.


Any expert there? Please share me some of your experience in making
the CMEX in PC/Win31/BC++3.1/MATLAB4.2,2a,2b (I know 2c cannot use BC++3.1).

The problem is:

I must use multiple files, which means, I have to do

cmex file1.c file2.c file3.obj file4.obj ...

and BC++3.1's TLINK ==ALWAYS== tells me the following

Turbo Link Version 5.1 Copyright (c) 1992 Borland International
Warning: Attempt to export non-public symbol MEXFUNCTION

Then, the final '.DLL' cannot be used. It will ALWAYS cause a 'general
protection error'.

I tried demo 'yprime.c', by using

cmex yrpime.c

it's okay. HOWEVER, if I use the BC++3.1's IDE to compile it first in obj,
use the same required options (as CMEX command-line!!), then

cmex yprime.obj

a '.DLL' file is generated but with a TLINK warning :

Warning: Attempt to export non-public symbol MEXFUNCTION

Then, in MATLAB, this DLL can not be used. It causes the 'general
protection error' as described above.

So, after nearly a week trial, I have to say, please help. HELP PLEASE.
I'm tired.

By the way, I tried BC++4.0.2, the same situation.

Best regards,
