Hello Sarankumar,
this very likely points to a linker problem. You have to make sure you
link against the right fftw libraries in your CMakeLists.txt's.
Best regards,
Marcus

Dear all,
I am trying to implement cross correlation block using fftw library. I
follow the correlation example in the gr-lte. when I try to run the block I
get the following error: importError:
/usr/local/lib/libgnuradio-my_xcorr.so: undefined symbol: fftwf_execute
I have fftw installed.
Any help?
Regards,
Saran
