compiling CUDA code to binary inside C++ file in VS 2010

I'm working to produce a plugin for a 3d application , this plugin uses that application SDK

in normal cases "personal test projects" , I separate .cu file and make its item type to CUDA C/C++ , and .cpp file to item type C/C++ compiler

here I want the whole code inside .cpp file and compile it without problems,

also I want to make the code (binary) so that I can hide the ptx (or kernels)

It's not entirely clear why you want to put CUDA code in a .cpp file. If the reason is due to some requirements of the SDK you are using, and you don't want to use nvcc, that won't work.

If you simply want to allow a .cpp file to contain device code and go through nvcc instead of directly to the host compiler, you can use the -x cu option on your nvcc compile command:

nvcc -x cu t264.cpp -o t264

The above command will generate the same executable just as if you had done this:

nvcc t264.cu -o t264

(assuming t264.cu and t264.cpp were identical files.)

If you want to strip out the ptx, you can compile like this:

nvcc  -gencode arch=compute_10,code=sm_10 -gencode arch=compute_20,code=sm_20 -gencode arch=compute_30,code=sm_30 ....

This will tell nvcc to create a fatbinary that contains executable binaries for sm_10, sm_20, or sm_30 devices, but no PTX.
