native dll's

[José Soriano Díaz]

Hi there, I'm working in a telerobotics project and I need to link a
windows dll in order to use a Cybernet Joystick.
        First I tried to use the winAPI functions LoadLibrary,FreeLibrary 
and
GetProccessAddress as I were working on Windows, and I recompiled my program
with winelib:
                *. winemaker /my_path/
                *. ./configure
                *. make all
        but it didn't create any executable, what I obtained was a lib*.so, 
because
winemaker thought I was trying to compile a dll, not to use one.
        After that I tried to compile my program without winemaker, and I 
obtained
a HEAP_PTR error when executing what I copiled. And If I tried to link the
lib*.so and load the main symbol I obtained the same error.
        So my question is quite siple How can I link a native dll in a Unix
project? I've read somewhere that I have to use a parser, Is there anybody
who can give me some code?

Thanks for your precious time.

To force winemaker to generate an executable simply use it as
follows:
 * type "winemaker --cuiexe /my_path" to indicate a console executable
 * type "winemaker --guiexe /my_path" to indicate a graphical executable

You can also use "winemaker -?" to get a list of options supported by
winemaker.

I think you have used the right approach: LoadLibrary /
GetProccessAddress / FreeLibrary. If that works for you then it's the
simplest approach.
