Thanks for quick reply! It does not work even if I use float precision as fftwf_complex *in2, *out2; out2 = (fftwf_complex*) fftwf_malloc(NFFT*2*sizeof(fftwf_complex)); in2 = (fftwf_complex*) fftwf_malloc(NFFT*2*sizeof(fftwf_complex));
I attach cmake files. It would be nice of you if you take a look. - NE Fri, 21 Mar 2014 11:18:45 +0100 от Marcus Müller <mar...@hostalia.de>: >-----BEGIN PGP SIGNED MESSAGE----- >Hash: SHA1 > >The (F) was meant to say: >Use FFTW3_LIBRARIES if you want to use the double precision version, >use FFTW3F_LIBRARIES if you want the single (float, 'F') precision >version of the library. > >Since you're using >fftw_malloc (without f suffix), you're trying to use the double prec. >version of the library, but you link against the single prec. version. > >Greetings, >Marcus > >PS: The GNU Radio complex data type is identical to the float complex >datatype used by FFTW3F.
