this is not correct. It is not DM_FPGA but only FPGA.

To solve this, added an inline empty stub in the header if
CC_OPTIMIZE_FOR_DEBUG is set such that the build will succeed.

Hello Michal,
Thanks for reviewing .
Chanho, I cannot try this at the moment, if you are in a hurry you can
send a v4 or v2 to your patch addressing this (or maybe your patch does
not have this problem)
Thanks,
Eugen
