Linking Issue!! #285

Closed kafi350 closed 3 years ago

kafi350 commented 3 years ago

Hello,

I was trying to link vexCL with and existing OpenCL project and it fails whenever i do the

include <vexcl/vexcl.hpp>

I am attaching the error in a text file.

Error.txt

Please let me know what's actually the issue as I tried almost all ways possible to resolve it.

It does not look like a linking error, it fails to compile judging by the log you attached.

How exactly are you building the project (command line with all the flags)? Can you reproduce the same issue with a minimal compilable example and post is here (again, both source code and the command line you use for building)?

The log says cl::Error type is undefined, but it should come from <CL/cl.hpp>, which should come from your OpenCL SDK (it is also provided at https://github.com/ddemidov/vexcl/tree/master/CL for convenience).

lol

Even If I try the normal initialization of VexCL the same error occurs.

Try to define the preprocessor macro CL_TARGET_OPENCL_VERSION=120.

It worked without changing the version. I did a clean openCL installation and Boost.Compute installation. Now it is building. Thank you!
