I am trying to compile the linux driver for a10_ref BSP on a Ubuntu 18.04 machine. the following error shows up:
aocl install: Adding the board package /home/ic611/intelFPGA_pro/19.3/hld/board/a10_ref to the list of installed packages

I think the driver is not compatible with linux kernel 5.0 yet. Hope this issue could be fixed for Ubuntu 18.04 as it is said to be supported. Both v19.1 and v19.3 SDK were tested.
