OpenCL interop version mismatch

[64]

Looks like the current version of ocl_interop on crates.io hasn't been updated in a while. It still depends on ocl 0.16.0 and gives a type mismatch when you try to use it with ocl 0.19.0:

error[E0308]: mismatched types

              found type `ocl::standard::context::Context`
note: Perhaps two different versions of crate `ocl` are being used?

I've forgotten about ocl_interop lately. I need to create a test for it or something to make sure it stays up to date...

Please feel free to submit a PR to update or else I'll take care of it tomorrow. I'm away from my computer for the day.

Thanks :)

I think the Cargo.toml is actually correct, but it just needs to be published.

[c0gent]

I see.

Do you happen to have SDL and GLFW installed? If so could you please try running the ocl-interop tests? I'm having all sorts of driver issues with OpenGL right now.

git clone https://github.com/cogciprocate/ocl.git
cd ocl/ocl-interop
cargo test

If that works I'll publish 0.2.0.

Does compile though. I'll hunt down where that error message is coming from and get back to you.

Looks like it's caused by this line:

let cl_buff =
    ocl::Buffer::<f32>::from_gl_buffer(ocl_pq.queue(), None, self.gl_buff).unwrap();

https://github.com/cogciprocate/ocl/blob/master/ocl/src/standard/buffer.rs#L1740

Could also be a driver issue. I remember trying to get some non-rust examples of interop to work, but they were all giving me the same error (CL_MEM_OBJECT_ALLOCATION_FAILURE on clCreateFromGlTexture).

[c0gent]

Ok well I'll mess with this on my laptop later if you can't get it to work. It's a pain to get everything set up properly to get these tests to run so thanks for trying.

Yep it's a driver issue on my end: intel/beignet#5

I'll try and fiddle a bit more.

Looks like we can't totally solve your problem but ocl-interop 0.1.5 is published.
