Creating a LIB or DLL

[Antonio Linares]

Dave,

Please add this code at the beginning of babudll.prg:

extern LoadLibrary, FreeLibrary, AnsiToWide

Please modify buildhd.bat to use gtgui.lib instead of gtwin.lib
and add this library too:

echo %bcdir%\lib\psdk\msimg32.lib + >> b32.bc This one !!!
echo %bcdir%\lib\psdk\rasapi32.lib, >> b32.bc

[Dave Zowasky]

Antonio,

Still have problem with :

_HB_FUN_LOADLIBRARY
_HB_FUN_FREELIBRARY
_HB_FUN_ANSITOWIDE

Here is my current babudll.prg:

Program:

Code: Select all

// To build BabuDLL.dll do: buildhd.bat babuDLL

// To run this DLL, do buidh.bat Babu.prg

extern LoadLibrary, FreeLibrary, AnsiToWide

function Test( cMsg1, cMsg2 )

   MsgInfo( cMsg1, cMsg2 )

return nil
 

Here is my current buildhd.bat :

Code: Select all

Dave,

Please add this library to buildhd.bat and try it again, thanks:

echo %hdir%\lib\rddfpt.lib + >> b32.bc
echo %hdir%\lib\hbwin.lib + >> b32.bc // this one !
...

[Dave Zowasky]

Antonio,

Added the line to the batch file and it creates the dll, however when I compile babu.prg and run
it I am getting :

An exception error(C0000005) occurred during DllEntryPoint or DllMain in module:
c:\fwh\samples\babudll.dll


Thanks

[Antonio Linares]

Dave,

Where have you downloaded maindll.c from ?

How have you compiled maindll.c ? What compiler flags have you used ?

[Dave Zowasky]

Antonio,

I used the latest maindll.c from the harbour-1.0.1\source\vm\maindll.c

I can post it if needed:

I added this to my buildhd.bat

%bcdir%\bin\bcc32 -c -D__EXPORT__ -I%hdir%\include;%bcdir%\include -L%bcdir%\..\lib maindll.c

Thanks

[vailtom]

Code: Select all

%bcdir%\bin\bcc32 -c -D__EXPORT__ -I%hdir%\include;%bcdir%\include -L%bcdir%\..\lib maindll.c

The are changed __EXPORT__ macro to HB_DYNLIB:

Code: Select all

See INSTALL file into source tree for more info.

[Dave Zowasky]

Vailton,

I appreciate the info, however I am not sure what to do with it.

Do I need to change my batch file from __EXPORT__ to HB_DYNLIB ?

Thanks

[vailtom]

When you compile a .DLL should not use the macro __EXPORT__ as it is in changelog, this was changed.
Maybe this could be it mixed in the command line you posted above.

[Antonio Linares]

Dave,

> Do I need to change my batch file from __EXPORT__ to HB_DYNLIB ?

Yes

Once the DLL is built, please do:

impdef.exe YourDll.DEF YourDll.DLL

and check the contents of YourDll.DEF. It is an ascii file that shows what symbols are exported from the DLL.

[Dave Zowasky]

Antonio,

Got this in mydll.def

LIBRARY BABUDLL.DLL

EXPORTS
__DbgWndProc @1 ; __DbgWndProc
__WndProc @2 ; __WndProc
___CPPdebugHook @3 ; ___CPPdebugHook

Not sure what to do next.

Thanks

[Antonio Linares]

Dave,

These lines should be inside the DEF file:

DllEntryPoint @894 ; DllEntryPoint
HBDLLENTRY @895 ; HBDLLENTRY
HBDLLENTRY1 @896 ; HBDLLENTRY1
HBDLLENTRY2 @897 ; HBDLLENTRY2

Those numbers can be different.

If you don't have them, then it means that maindll.obj is not being properly built.

[Antonio Linares]

Dave,

Please make these changes in maindll.c, and compile it again and build the DLL:

BOOL WINAPI __export DllEntryPoint( HINSTANCE hInstance, DWORD fdwReason, PVOID pvReserved )

LONG PASCAL __export HBDLLENTRY( char * cProcName )

LONG PASCAL __export HBDLLENTRY1( char * cProcName, LONG pItem )

LONG PASCAL __export HBDLLENTRY2( char * cProcName, LONG pItem1, LONG pItem2 )

[Dave Zowasky]

Antonio,

Like:

HB_EXPORT BOOL WINAPI DllEntryPoint( HINSTANCE hInstance, DWORD fdwReason, PVOID pvReserved )

to

BOOL WINAPI _export DllEntryPoint( HINSTANCE hInstance, DWORD fdwReason, PVOID pvReserved )

Also

You have
__export

should I use?
_export


Correct?

If so still have same


Thanks

Code: Select all

HB_EXPORT BOOL WINAPI DllEntryPoint( HINSTANCE hInstance, DWORD fdwReason, PVOID pvReserved )
{
   HB_TRACE( HB_TR_DEBUG, ("DllEntryPoint(%p, %p, %p)", hInstance, fdwReason,
             pvReserved ) );

   HB_SYMBOL_UNUSED( hInstance );
   HB_SYMBOL_UNUSED( fdwReason );
   HB_SYMBOL_UNUSED( pvReserved );

   switch( fdwReason )
   {
      case DLL_PROCESS_ATTACH:
           hb_vmInit( FALSE );  /* Don't execute first linked symbol */
           break;

      case DLL_PROCESS_DETACH:
           hb_vmQuit();
           break;
   }

   return TRUE;
}

HB_EXPORT LONG PASCAL HBDLLENTRY( char * cProcName )
{
   hb_itemDoC( cProcName, 0, 0 );

   return 0;
}

HB_EXPORT LONG PASCAL _export HBDLLENTRY1( char * cProcName, LONG pItem )
{
   hb_itemDoC( cProcName, 1, ( PHB_ITEM ) pItem, 0 );

   return 0;
}

HB_EXPORT LONG PASCAL t HBDLLENTRY2( char * cProcName, LONG pItem1, LONG pItem2 )
{
   hb_itemDoC( cProcName, 2, ( PHB_ITEM ) pItem1, ( PHB_ITEM ) pItem2, 0 );

   return 0;
}
 

[Antonio Linares]

Dave,

Just to be sure that HB_EXPORT gets properly translated, better replace those lines as I have explained you and compile it again.
