Link error while Compiling CUDA from command prompt

I'm trying to compile a CUDA test program on Windows 7 x64 via Command Prompt using this command:

nvcc cuda.cu

I get the following output and then this error message:

cuda.cu
tmpxft_00000d14_00000000-3_cuda.cudafe1.gpu
tmpxft_00000d14_00000000-8_cuda.cudafe2.gpu
cuda.cu
tmpxft_00000d14_00000000-3_cuda.cudafe1.cpp
tmpxft_00000d14_00000000-14_cuda.ii
LINK : fatal error LNK1104: cannot open file 'kernel32.lib'

I have the kernel.lib file in C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Lib and adding that to the CUDA lib environment variable doesn't work.

What would be causing this error and how do I rectify it?

Try adding "-machine 32" as an argument - captain
Tried it @Jay It says nvcc fatal : 'achine': expected a number. Then tried "--machine 32" still gives, LINK : fatal error LNK1104: cannot open file 'kernel32.lib' - TheGame
How about -m64 since you are on a 64-bit OS? - harrism
Tried it @harrism It gives the same error. - TheGame
Actually you need a host compiler to build CUDA code, so even with a correct library location you might not be able to build. See the CUDA release notes. - harrism

You should not specify the MS lib location in an environment variable. You need to use a '-L' command line option as in

nvcc <file> -L"C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Lib"

Really you probably need Visual Studio installed because you need a host compiler to build your host code.
