Re: [Discuss-gnuradio] How to link gnuradio library with applications outside of gnuradio/usrp?

[Marcus Müller]

Hi Marcus M (cool name, actually),

gr_complex is an STL complex<float>, so you won't need the complete GR 
core to use it:
gnuradio-core/src/lib/runtime/gr_complex.h:typedef 
std::complex<float>    gr_complex;

gri_fft requires only gr_complex (see above) and gr_sys_paths, which is 
essentially replaceable by
string literals. (and boost filesystem&threads and fftw of course, but 
those are not part of GR)

By the way: You'll be benchmarking FFTW (float implementation) 
complex2real fft, why would you want
to use it wrapped in gri_fft? Using FFTW is -after all- three lines of 
code, using the benchmarking
functions one line more.

Hope this was helpful,

greetings
Marcus Müller
