[Discuss-gnuradio] FFTW usage in a new signal processing block

[Felipe Fideles]

Hello All,

I'm trying to use FFTW in the development of a new signal processing block. 
The ./boostrap and ./configure commands work fine, but when I type the make command, I get the following error:

/usr/src/gnuradio/gr-deteccao/lib/.libs/libgnuradio-deteccao.so: undefined reference to `fftw_execute'

/usr/src/gnuradio/gr-deteccao/lib/.libs/libgnuradio-deteccao.so: undefined reference to `fftw_plan_dft_1d'
/usr/src/gnuradio/gr-deteccao/lib/.libs/libgnuradio-deteccao.so: undefined reference to `fftw_destroy_plan'

collect2: ld returned 1 exit status

It sounds weird because the fftw in already at the gnuradio files.
