Hi there, This is what I achieved. Installed Ubuntu 14.04 with AMD Catalyst 15.302 in a Dell7910 with 2 Xeon E5-2609 v3, 32Gb RAM, Fury tri-X R9 GPU Compiled & run arrayfire examples, but it runtime complained. ./blas_opencl peak 4434.43 GFLOPSInstalled Revolutions R with MKL

@AurelioG I see that the C/C++ version is using 3.3.2 where as you are loading 3.2 for R. Can you try with 3.3 ? I just ran the same code on an R9 Fury nano and did not get any errors. If that doesn't work, can you post the output of |

No Joy yet.. I tried 3.0 and could not install properly. I tried different things starting from clean install and probably glfw is a source of headache, arrayfire binaries or compile is another flavour of problems. Here is what works with arrayfire-r > afInfo()

@AurelioG That's weird. I tried the same code on my machine without any issues.. The error you are seeing seems to be coming from the OpenCL driver.. |
|
Apparently this can happen if you have an older version of AMDAPPSDK installed along side the newer version. Can you check if that is the case? |

Here is the R output with a clean Ubuntu 14.04 install, but my R snippet didn't work. However the errors are different. The arrayfire examples were OK, except for the graphics. This time I didn't install OpenCL GL headers, mesa or other stuff that could interfere with the AMD SDK. So my question is ¿how to set up a working OpenCL environment for arrayfire-r? I'm not interested (yet) in the arrayfire graphic capabilities. Previously, I tried to disable GLFW when compiling Arrayfire, but I got errors complaining about glfw. Cheers,

@AurelioG is that the end of the error message ? If not, can you run your script after running |

Yes it was the end of the R printout in RStudio!

@AurelioG let me try out RStudio and see what's going wrong. I have only ever used command line. |
Each header "foo" file should have the following:
Also add tests if possible, though they are not necessary
C++ only headers that are not being ported
