Hi Mischa,
we need to make an FAQ of this :)
actually, to use the fftw, you need to directly link to the fftw. Depending on whether you need the
single precision floating point version ("fftwf_*" which GNU Radio uses) or the double
precision one ("fftw_*"), you can use the FindFFTW3(f).cmake sc
Dear all
I try to link the FFTW3 lib to my OOT module but always get the error:
Linking CXX executable test-mymodule
libgnuradio-mymodule.so: undefined reference to `fftw_plan_dft_1d'
libgnuradio-mymodule.so: undefined reference to `fftw_destroy_plan'
libgnuradio-mymodule.so: undefined reference
