Hi,

I am sorry for the late response. I installed 19.1 but trying to compile any kernel using the fast emulator fails with:

Error: OpenCL kernel compilation FAILED

The ioc.log contains the following lines:

Using build options: -cl-std=CL1.2 -Xclang -Wuninitialized -I "/home/user/vector_add/device"

Failed to get platform id...: 0 (CL_SUCCESS)

Compilation failed!

Any thoughts on what might be the problem?
