Finding Delcarations and Definitions of Cuda types

Accelerated Computing CUDA CUDA Programming and Performance

Hi there,

after installing the SDK on Visual Studio 9, and working through a couple of listings from “Cuda by Example”, I noticed that the types used by Cuda
(e.g. cudaError_t) cannot be accessed through VS’s “Go to Declaration” or “Go to Definition”. I presume that the nvcc compiler adds a lot of header files that contain these, and that they are hidden from Visual Studio before that.

Am I correct in this assumption, and is there any tooling to turn source-code-navigation on for these types?

Thanks,

Sebastian.

Another issue: Code folding and brace matching are broken. I managed to get syntax highlighting to work, but that seems to be all of the luxury. Even the conventional code can no longer be navigated with F12, as I noticed. This is like the eighties!

Yeah the installation on my PC has this problem too, I suspect it’s some sort of path problem.

I just tried to figure it out in an ms-dos prompt the following happened:

Without quotes:

C:\Users\Skybuck>%CUDA_PATH%
‘C:\Tools\CUDA\Toolkit’ is not recognized as an internal or external command,
operable program or batch file.

With quotes:

C:\Users\Skybuck>“%CUDA_PATH%”
‘"C:\Tools\CUDA\Toolkit 4.0\v4.0"’ is not recognized as an internal or external
command,
operable program or batch file.

Notice how the first one seems to be incomplete, it’s because there is a space in the folder.

Perhaps this is causing Visual Studio to not find these include files ?!?

For example:

CUDA_INC_PATH is declared as:

%CUDA_PATH%\include

Perhaps adding quotes around it might solve it…

I’ll give it a try and see if it helps External Image

Hmmm, strangely enough at the moment it is working… don’t know if it was something I did… might be because my virtual drive had “lucky” drive letter assignments…
