Dear all,

I'ml currently trying to develop a 3D GPU based segmentation plugin for ImageJ. I learned Cuda programming on this wonderful website :

https://www.udacity.com/course/cs344

And I usually develop in Java by using the IDE Netbeans.

I first wrote my ImageJ plugin without GPU computing. I see my method is working, but very slow as expected. I need to speed up the process using GPUs. And I'm stuck at setting the correct CUDA environment...
Is there anyone that can help me ?

- I have Windows 7 64 bits,
- I installed the last Cuda toolkit v6.5
- and the binaries for windows x64  of JCuda http://www.jcuda.org/downloads/downloads.html
- I can provide more informations if necessary...

At this point I have to admit I'm lost and desperate - I setup a lot of environment variables so that some dll can be linked correctly - I copied and paste the jar and dll of JCuda a bit everywhere in the folders so that Java could find it at least in one place... I know that something happened since the error when I tried to compile "Simple_JCuda_Plugin.java" has changed. But know I'm stuck, having desesperately the same error (listed at the end of this email).

Is there anyone who can help me or who knows a more simple way of developping using Cuda (maven ? / Change OS ? ).

Some help would be very much appreciated...

Thanks

Nicolas
