link error using nvmex in matlab

Accelerated Computing CUDA CUDA Programming and Performance

hi,

I`m using Matlab 7.3.0(R2006b) and Microsoft Visual Studio 8.

I downloaded the newest matlab plugin for cuda:

http://developer.nvidia.com/object/matlab_cuda.html

Now I try to run the examples in the readme file. Everything works fine, but linking with nvmex doesnt work:

nvmex -f nvmexopts.bat Szeta.cu -IC:\cuda\include -LC:\cuda\lib -lcufft -lcudart

Szeta.cu 

c:\cuda\include\common_functions.h(56): warning: dllexport/dllimport conflict 

		  with "clock" (declared at line 176 of "C:\Programme\Microsoft Visual 

		  Studio 8\VC\INCLUDE\time.h"); dllimport/dllexport dropped

??? Error using ==> nvmex

Unable to complete successfully.

How can i get this running?

best Regards

I had the same problem when I tried this in Windows. I think I solved it by installing the Windows SDK ( I am using VC++2005 express though) and setting the paths in the nvmexopts.bat file to point to the SDK, as well as ensuring that none of the paths had spaces in them (I can’t remember why, but something seemed to have a problem with them.)

Hopefully that was all I did, cause it works now on my machine.
