error LNK2019: unresolved external symbol

Accelerated Computing CUDA CUDA Programming and Performance

I’m trying to run the following command:

nvcc …/src/cuda/bitcoinminercuda.cu -gencode arch=compute_10,"code=sm_10,compute_10" -gencode arch=compute_11,"code=sm_11,compute_11" --keep -gencode arch=compute_20,"code=sm_20,compute_20" --keep --machine 32

I’m getting this error:

libcmt.lib(crt0.obj) : Error LNK 2019: unresolved etneral symbol _main referenced in function
___tmainCRTSTARTUP
a.exe : fatal error LNK1120: 1 unresolved external

I’m using Visual Studio 2010 Express. Anyone able to help me resolve this issue?

Maybe this will help anyone to point me in the right direction:

I used --Verbose to get below:

#$ cl -nologo -c -TP “-I./…/include” “-I./…/include/cudart” “-IC:/Program Files (x86)/Microsoft Visual Studio 10.0/VC/include” -EHsc “bitcoinminercuda.cu.cpp.ii” -Fo"bitcoinminercuda.obj"
