CL/cl.hpp: No such file or directory | NVIDIA GeForce

Question

Good afternoon! I'm trying to run code in C++ that has the following line:

#include <CL/cl.hpp>

But launching the program gives this error:

fatal error: CL/cl.hpp: No such file or directory

What have I tried to do?

Completely reinstalling mingw64
Uninstalled Visual Studio 2019 and installed Visual Studio 2022
Installed NVIDIA Cuda according to the instructions (I also updated the NVIDIA drivers): https://docs.nvidia.com/cuda/cuda-installation-guide-microsoft-windows/index.html

Cuda is fully operational. I checked with the code examples that come with CUDA.

P.S. As far as I know, OpenCl is part of CUDA.

Thanks!

I assume you did not add the include path. `#include ` will only work if your compiler has the folder containing the CL folder in its list of Include directories. — drescherjm, Jan 26 '22 at 19:54
`-I` sets the include directory on that compiler. How you set that depends on how you are building. — drescherjm, Jan 26 '22 at 19:59

It is best to include the OpenCL headers in the same directory where the source code of your Visual Studio Project is. You then have to tell Visual Studio where these files are located. To configure the project and set the file paths, see this answer.

You don't need to install CUDA at all. The OpenCL Runtime is included in the Nvidia graphics drivers already.

Do you mean to follow the link or copy the header to the source code location? – AquaAsh Feb 08 '22 at 12:32
Download the headers from the link, then copy the OpenCL folder containing the headers into your source code location. – ProjectPhysX Feb 09 '22 at 07:24
