Ok, please forgive my naivety but this is my first attempt and all,<br><br>I am lost and need come guidance, the guide is of some help and so is looking at the opengl files. I am not sure exactly what I am trying to write. What is the difference between a dll form Wine and a dll.so? I know the dll.so end up in your linux /lib folder right? How does a dll communicate to this dll.so? How am I to write this dll file so that when the fah gpu app calls for a function the cudart.dll file acts as a link to the libcudart.so.2.0? I don't want to attempt to rewrite the entire dll if I don't have to. To me it just seems like I am not getting the picture. I know we can't simply link the two files because they are in two different formats ELF vs PE. Is there a good example on how this is done? I'm sure this has been done before. Again looking to the opengl_norm.c file all it appears is that every functions has been rewritten but with "wine_" in front of the function name. Is that all I need to do with the cudart? That just seem right.<br>
<br>I probably should even be messing with this stuff, but the beautify of open source applications is that with a little help from the community I can add in support for things I need (CUDA). If this was a closed source app, I would have to just put in a request for it and maybe in a few months or so they might think about adding support.<br>

part. You *may* want to write this DLL as part of Wine, although I am afraid
that we don't have a policy how to deal with non-Windows DLLs(since cuda is an
Nvidia thing, not from MS). Of course the 5.5 part doesn't apply then as well.</span></p>

<p style="margin-bottom: 12pt;">I writing a wrapper, would it
be correct to more or less follow this guide, on winelib dll's? <a href="http://www.winehq.org/site/docs/winelib-guide/bindlls" target="_blank">http://www.winehq.org/site/docs/winelib-guide/bindlls</a><br>
<br>
I've never coded anything for Wine before so I want to make sure I do it right
from the beginning instead of having to go back and make drastic changes.<br>
<br>
I'll be looking at that opengl32 perl script because there is 102 pages of
functions that cudart.dll and libcudart.so both contain.<br>

<p>This is not going to work. PE style dynamic linking works

different from ELF style dynamic linking. Wine can not link native ELF<br>

special in being ELF files but containing extra information that allows<br>
the Wine dynamic linker to link it into PE processes.</p>

<p style="margin-bottom: 12pt;">This is right. You need at
least a correct .spec file to make a wine<br>
dll. You still have to implement a wrapper for each function, as Windows<br>
usually uses the stdcall calling convention, whereas linux uses cdecl by<br>
default. There might be some way to automate writing the wrapper<br>
functions.<br>
