Hi everyone,
I'm using Ubuntu 20.04,, UHD 4.2.0 and GNU Radio 3.8. I'm using also an USRP
X310 for RFNoC development but I'm getting problems when I'm creating the FFT
block. Once I've changed all the Verilog files, all the .yml and all the
controllers, I see that the files named fft_impl.cc and fft_impl.h, which are
the GNU Radio block C++ code, are not provided in UHD. As I don't have them, I
use te default blocks that rfnocmodtool provides by default. After I use make
in the build directory I get the next error:
[ 6%] Building CXX object lib/CMakeFiles/gnuradio-bloquefft.dir/fft_impl.cc.o

Anyone had a similar result and could resolve it? Or I just don't have a file
that is necessary?
Thank you everyone
Benito
