nvcc not working

hi all

I recently installed CUDA driver, toolkit and SDK 3.2

but it is not working

I ran a sample code from SDK marchingCube

it showed an error message as below

Error 2 fatal error LNK1181: cannot open input file ‘.\Debug\marchingCubes_kernel.cu.obj’ marchingCubes marchingCubes

I think maybe the nvcc is somehow not working, but i don’t know why

I also try to install 4.0 but still the same problem

right click on the cu file and compile it , it won’t show any error message

the command line of the building rule is as below

echo "C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v4.0\bin\nvcc.exe"    -gencode=arch=compute_10,code=\"sm_10,compute_10\" -gencode=arch=compute_20,code=\"sm_20,compute_20\"  --machine 32 -ccbin "C:\Program Files\Microsoft Visual Studio 9.0\VC\bin"    -Xcompiler "/EHsc /W3 /nologo /Od /Zi   /MTd  " -I"../../common/inc" -I"C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v4.0\include" -maxrregcount=0  --compile -o "Debug/marchingCubes_kernel.cu.obj" marchingCubes_kernel.cu 

           "C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v4.0\bin\nvcc.exe"    -gencode=arch=compute_10,code=\"sm_10,compute_10\" -gencode=arch=compute_20,code=\"sm_20,compute_20\"  --machine 32 -ccbin "C:\Program Files\Microsoft Visual Studio 9.0\VC\bin"    -Xcompiler "/EHsc /W3 /nologo /Od /Zi   /MTd  " -I"../../common/inc" -I"C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v4.0\include" -maxrregcount=0  --compile -o "Debug/marchingCubes_kernel.cu.obj" "c:\Documents and Settings\All Users\Application Data\NVIDIA Corporation\NVIDIA GPU Computing SDK 4.0\C\src\marchingCubes\marchingCubes_kernel.cu"

can somebody help me with this

thanks!
