Another topic on DLL problems

I have tried to create a DLL using Dev-cpps DLL template

my dllmain.cpp reads
---------
#include <windows.h>
#include "patch.h"
#ifndef DLLEXPORT
#define DLLEXPORT __declspec (dllexport)
#endif

//Export List
DLLEXPORT int addpatchdata(const char patchfile[],
                 const char sourcefile[],
                    long int lowerb,
                  long int upperb);
                 
DLLEXPORT int createpatchfile(const char *ccfilename);

DLLEXPORT int patchfile(char patchfile[],char targetfile[]);
--------

and my DEF file looks like this

--------
LIBRARY "patch.dll"

EXPORTS
patchfile
createpatchfile
addpatchdata
-----

when i attempt to compile it, there is an error, even though the DLL compiles, it appears that the funcitons are not exported

compile log

then i add the option --def
patch.def

and the following compile log results

i went through the forum and tried various ideas, having written the DEF file myself, as it was not generated by the DLL template.

any ideas would be appreciated, ive been browsing the web nonstop for hours for a solution.

I don't know about GCC but when using MSVC and writing a .DEF file the exported functions were of the format

FunctionOne       @1
FunctionTwo       @2

.. and so on. Each digit ID must be unique.
