Does CUDA SDK 3.x support to generate cubin?

I get following error when I compile the .cu file to cubin, why?

“C:\CUDA\bin\nvcc.exe” -m32 -gencode=arch=compute_20,code="sm_20,compute_20" -ccbin “C:\Program Files\Microsoft Visual Studio 9.0\VC\bin” -D_DEBUG -D_WIN32 -I"C:\CUDA\include" -I"./" -I"…/…/common/inc" -I"…/…/…/shared/inc" -Xcompiler "/EHsc /W3 /nologo /Od /Zi /MT " -maxrregcount=32 -gencode=arch=compute_20,code="sm_20,compute_20" -cubin -o “data\matrixMul_kernel.cubin” “c:\CUDA_SDK\C\src\matrixMulDrv\matrixMul_kernel.cu”

nvcc €=å®”X: Option ‘-cubin’ is not allowed when compiling for multiple GPU code instances

Replace the -gencode=… arguments by a simple -arch=sm_20.
