[Discuss-gnuradio] Frustrating

[Moir, Tom]

I am getting to the stage where I am compiling the core and get teh following 
error messages


../../src/lib/.libs/libgnuradio-core.so: undefined reference to 
`fftwf_import_wisdom_from_f ile'
../../src/lib/.libs/libgnuradio-core.so: undefined reference to `fftwf_free'

I have installed  FFTW so I cannot see why it cannot find these references?
Can anybody help?

Thanks

Tom
