Unable to compile OpenCL kernel for FPGAs in Devcloud

Hello all, I'm trying to compile an OpenCL kernel for an FPGA in the Devcloud, using the supplied version of `aoc`. The kernel itself is attached to the post (It has a .c ending because the forum wo...

Oh, there's another update: Apparently, you have to tell aoc which BSP to use. Otherwise, it will use none or a wrong one and the computer can't communicate with the FPGA card once it was programmed. The setup is the same as described before, but I'm using

aoc gauss.cl -o gauss.aocx -board=pac_a10 -board-package=/opt/intel/inteloneapi/compiler/2021.1-beta03/linux/lib/oclfpga/board/intel_a10gx_pac

instead of

aoc gauss.cl -o gauss.aocx

Once the workaround from above is implemented (copying `gauss/build/output_files/dcp.green_region.pmsf` to `gauss/build/output_files/afu_import.green_region.pmsf` once possible) and the compilation is complete, the kernel can be used just fine.

The only problem that's left is the fact that the file `gauss/build/output_files/dcp.green_region.pmsf` is either non-existent or isn't generated.
