Compiling kernel on HD 505 (Apollo Lake)

How should I interpret this error?

I'm compiling an OpenCL 1.2 kernel from source. It compiles fine on a HD 530/x64/Skylake device.

But I'm seeing these errors when compiling the same kernel source on an HD 505 / N4200 / x64 executable.

This problem was resolved. I removed the "-std-cl=..." option from the clBuildProgram() and the problem went away.

I can also confirm the HD505 performs really really well with my compute kernels!
