Antonio - dll2lib para MSVC

[Rossine]

Olá Antonio,

Como converto uma .DLL em uma .LIB usando MSVC ?

Montei um fluxo como está abaixo. A .lib é gerada mas as funções não estão sendo inclusas na .lib.

Code: Select all  Expand view  RUN

@echo off

if NOT EXIST %1.dll GOTO :NOEXIST

lib /def:%1.dll /out:%1.lib
GOTO OK

:NOEXIST
ECHO Connot find %1.dll
GOTO EXIT

:OK
ECHO Build %1.LIB ok!

:EXIT

impdef.exe %1.def %1.dll
lib.exe /def:%1.def

Olá Antonio,

Ao tentar converter a grfinger.dll me é retornado estes erros:

Code: Select all  Expand view  RUN

grfing.obj : error LNK2019: unresolved external symbol __imp__GrInitialize@0 referenced in function _HB_FUN_GRINITIALIZE

O que fazer ?

Rossine,

Por favor muestra aqui el contenido de grfinger.def, gracias

Rossine,

"The __imp_ prefix is used for symbols declared __declspec(dllimport). This
method provides a slightly more efficient access mechanism. It sounds like
you're compiling to use some DLL but not linking with that DLL's .lib file."

Whats the contents of GRFINGER.h ?
How are you declaring those functions from your C code ?

Rossine,

Please replace in grfinger.h:

#define DLLIMPORT __declspec(dllimport) int __stdcall

with:

#define DLLIMPORT int __stdcall

and try it again, thanks

[Rossine]

Olá Antonio,

Trocando:

#define DLLIMPORT __declspec(dllimport) int __stdcall

por:

#define DLLIMPORT int __stdcall
