I'm trying to compile the following code by Joe Stam (convolutionapproaches, project with vs2005, I am using VS2010 but compiling with 9.0 engine)

This with /MDd for code generation and CUDA C/C++ Runtime Host library.
If I switch to /MTd for both is the same.
What's wrong with this? I tried both the 32 bit and the 64 bit SDK, the toolkit is 6
回答1:
There was a problem with 32/64 bit sdks, I solved by linking with the 32 bit
