Opencl code compiles on aoc 16.0 but gives weird quartus error: "_wrapper.vhd file not found" on aoc 17.1

Hi,

I have a design that works perfectly fine on aoc 16.0 (both FPGA and emulator). However, when I compile this design ( by replacing "altera" with "intel" in the opencl code) using aoc 17.1, I am giving this quartus error:

Any suggestions what is the issue?

Thanks,

Could be a BSP issue or an issue specific to Quartus v17.1. What board/BSP are you using? And have you tried any other versions of Quartus? Like 17.0 or the latest 18.1 (if you have a compatible BSP)?

It was because I was using double underscores in kernel names like "A__loader" etc. Seems like double underscores in kernel names are allowed in 16.0 but not in 17.1.
