CUDA Project Structure

The template and cppIntegration examples in the CUDA SDK (version 3.1) use Externs to link function calls from the host code to the device code.

However, Tom'开发者_如何学JAVAs comment here indicates that the usage of extern is deprecated.

If this the case, what's the correct structure for a CUDA project such as the template example or cppIntegration example?

Depends what your host code is. If you end up mixing C and C++ you still need the externs. For details see this guide.
