Re: [Starpu-devel] SOCL on Ubuntu error

[Malcolm Roberts <malcolm.i.w.roberts@gmail.com>]

Hello.

I checked, and the file

SOCL_OCL_LIB_OPENCL=/usr/lib/x86_64-linux-gnu/libOpenCL.so

does indeed exist.

I looked for an .icd for SOCL in /etc/OpenCL/, but it wasn't there, so 
changed the line in my .bashrc:

#export OCL_ICD_VENDORS=socl/vendors/
export OCL_ICD_VENDORS=${HOME}/src/starpu/starpu-1.2.0rc4/socl/vendors

Now, clinfo works, and I can get a basic program to work.  I still get a 
segfault if I ask for the OpenCL device name, but the basic 
functionality of SOCL seems to work.  Now I will try to get a more 
complicated example to work.

Thanks for your help!

Best,

~Malcolm
