I believe the key line is Invalid address (0x7b877d07 start_process+0xc7) for
breakpoint 0, disabling it . But what exactly that means I am not sure, I mean
I don't know which function it is saying is missing or messed up. Also from the
documentation and from the nvidia forums it seems that both libraries are
exactly the same, and it is said that there is no difference in writing a
program for Linux vs. Windows, but I assume that is minus the direct3d
functions, which I know the folding at home program doesn't use.<o:p></o:p></p>

<p>Well at least it compiled, but it isn't working. We are still getting the
message that the function isn't implemented.<o:p></o:p></p>

Initializing Nvidia gpu library<br>
cudaMalloc CUDAStream::Allocate failed feature is not yet implemented<br>
<br>
<br>
Now both cudamalloc and all four cuda stream's, cudaStreamCreate, Destroy,
Query and Synchronize were implemented.<br>
I thought maybe it was because in the spec file I had the cudaStream's as
pointers (ptr) so I switched them to long but ti didn't make a difference.
Originally the argument was "stream" but I can't get any argument but
ptr and long to pass the winegcc for spec files.<br>

Does wine need to somehow be made aware of the presence of the <a
href="http://cudart.dll.so" target="_blank">cudart.dll.so</a> file? We tried
putting it in both the system32 and the lib folder but it seems also that maybe
WINE needs to be made aware of it?<o:p></o:p></p>
