Not all blocks support C++ code generation. I haven't tried generating C++, actually. Do you need that?

Unfortunately at the moment I have only a computer with GR 3.8.1
The fft_logpowerfft_x.block.yml file contains the line with mentioned code.
When I removed it, the error is gone and "FFT Size" is displayed in
black not red. This is a good news.
Unfortunately, new error appears:
logpwrfft_x_0 This block does not support C++ output
