Ok, then according to your output in the last post, gnuradio
configuration did not set the paths correctly.

Two things are missing, the linker command does not include the library
(i.e. -lfftw3f) and not the library path (-L/home/klonuo/.local/lib).
The latter is instead just appended to that last command which is wrong.
FFTW3F_LIBS should be something like this '-L$HOME/.local/lib -lfftw3f'
