Maurizio,

Try it this way:

c:\vce\bin\link /IMPLIB:rchglobe.dll /OUT:rchglobe.lib

This is the result:

The above was wrong. This should be the right way:

c:\vce\bin\lib /list:rchglobe.def rchglobe.dll

c:\vce\bin\lib /def:rchglobe.def /out:rchglobe.lib /machine:arm /subsystem:windowsce

To create the DEF file, better use Borland:

impdef.exe rchglobe.def rchglobe.dll

and then use Microsoft lib as explained

Ok, the lib is created (but it was with my command too).

Maurizio please try it.

Enrico,

ops, I missed your command

No problem. My command doesn't work anyway. The lib is created but errors out when is linked to the application.

EMG

Thank Antonio and Enrico

Now I have the LIB , and I cann link it without problem .

I try this function

pragma BEGINDUMP

include <hbapi.h>

HB_FUNC( RCHSENDDATA )
{
hb_retnl( RCHSendData( hb_parc( 1 ), hb_parc( 2 ) ) );
}

pragma ENDDUMP

But I have this error :

RCH.obj : error LNK2019: unresolved external symbol "int __cdecl RCHOpen(void)" (?RCHOpen@@YAHXZ) referenced in function "void __cdecl HB_FUN_RCHOpen(void)" (?HB_FUN_RCHOpen@@YAXXZ)
RCH.exe : fatal error LNK1120: 1 unresolved externals
//---------------------------------------------------------------------------
I Try this function

pragma BEGINDUMP

include <hbapi.h>

include <windows.h>

int RCHOpen( void );

HB_FUNC( RCHOpen )
{
hb_retnl( RCHOpen() );
}

pragma ENDDUMP

Creating library RCH.lib and object RCH.exp
RCH.obj : error LNK2019: unresolved external symbol "int __cdecl RCHOpen(void)" (?RCHOpen@@YAHXZ) referenced in function "void __cdecl HB_FUN_RCHOpen(void)" (?HB_FUN_RCHOpen@@YAXXZ)
RCH.exe : fatal error LNK1120: 1 unresolved externals

What is my error ?

Regards MAurizio

It seems a name-mangling problem as if the lib was compiled in C++.

EMG

Maurizio,

You have to include this in your code before your HB_FUNC()s:

Thank Antonio
Now I have this error

This is the source

pragma BEGINDUMP

include <Windows.h>

include <hbapi.h>

extern "C" {
LONG RCHSendData( LPSTR, LPSTR );
LONG RCHOpen( void );
LONG RCHClose( void );
}
HB_FUNC(RCHSENDDATA)
{
hb_retnl(RCHSendData(hb_parc(1),hb_parc(2)));
}

int RCHOpen( void );

HB_FUNC( RCHOpen )
{
hb_retnl( RCHOpen() );
}

int RCHOpen( void );
HB_FUNC( RCHOClose )
{
hb_retnl( RCHOpen() );
}

pragma ENDDUMP

Maurizio,

Remove these lines from your code:

BTW,

This is wrong:

HB_FUNC( RCHOClose )
{
hb_retnl( RCHOpen() );
}

it should be

HB_FUNC( RCHClose )
{
hb_retnl( RCHClose() );
}

Finally, please use uppercase for names HB_FUNC ( ...Uppercase!... )

i.e.:

HB_FUNC( RCHCLOSE )

Wow !!
Finally, thanks to your help the link to the LIB works.

Many, many thanks to Antonio and Enrico for your assistance.

The strange thing is that when I linked the LIB and inserted the code to
call the functions in the LIB, the calls to the DLL now works.
This might explain the reason why the calls to the DLL did not work before?

Maurizio
