error LNK2019: unresolved external symbol using nvmex Problem wiht CUDA programs in Matlab

Accelerated Computing CUDA CUDA Programming and Performance

I have already read many guides and tutorial publised by NVIDIA or other publiser,I have been trying to use cuda in Matlab.I have faced so many problem in this process and I have succeed to solve all those problem.But now I am facing a new problem to compile Szeta.cu program or other Cuda programs.Following are the error message:

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

??? Error using ==> nvmex
Unable to complete successfully.

I understand this is a linker problem.I have no idea to solve it.
Following are Detail of my system:
1.window 2007 ulimate
2.Matlab version:7.1.0.246 (R14) Service Pack 3
3.cudatoolkit_2.3_win_32
4.cudasdk_2.3_win_32
5.Visual stdio 2005 express c++
Plz tell me I can I solve this problem?
Thanks in advance

Hi Monika

As far as I can see, you just supply a library path, but you don’t define the actual libraries you have want to link to your code. My compile instruction is a bit different from yours since I use vc++ to create a static library which I link to, but this is what I use:

nvmex -O -output cudaMex -Iinc -Lc:\cuda\lib -Ic:\cuda\include -lcuda -lcudart -LRelease -lcudaLib cudaMex.cpp

What you want to include in your project is the
-lcuda -lcudart

Where the first is a lowercase L. That will link the cuda.lib and cudart.lib file. Unless you want to use the dll’s, in which case I can’t help you.

Hope it works
