在VS 2010中将CUDA代码编译为C ++文件中的二进制文件

Question

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)

Answer 1

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.
