Exemple avec C++Builder

Bonjour,
J'essai de compiler l'exemple avec C++Builder, mais invariablement, je tombe sur les erreurs suivantes:

J'ai certainement oublié un lien, malgré mes recherches sur le forum.

Merci

Avez vous inclus le .lib???

Oui, dans les options du projet j'ai ajouté les chemins "C:\Program Files\GflSDK\bcc" et "C:\Program Files\GflSDK\include"

Essayez de recréer les .lib à partir des .dll avec les outils de borland.

I understand a little French, while I have a hard time to write in that language, hence Ill stick to English. :p

There is a problem in the header files which may cause BC++ to take some wrong defines that declare the calling convention.

The problem is that BC++ for some reason sees:

Code: Select all

#ifdef WIN32 is FALSE

This causes:

Code: Select all

#define GFLAPI

instead (of correct calling convention setting)

Code: Select all

#define GFLAPI __stdcall

Thats whats actually causing the "unresolved externals" errors.
It's incorrectly cdecl here instead of stdcall (cdecl because of extern "C") FWIK.

I (in my final header-files version) replaced:

Code: Select all

#ifdef WIN32

with

Code: Select all

#if defined( WIN32 ) || defined ( __BORLANDC__ )

(3 occurences in libgfl.h and also some in libgfle.h IIRC)

Note for Pierre:
This may cause errors in CBuilderX?
Not sure -> untested.
But when building under linux...
