i had compile the code and installed the block successfully.
but now while running i am getting error.
Traceback (most recent call last):

i am wonder whether comedilib is link to gnuradio or not.
because while installing block i didn't get any error as far as comedilib
functions are concern.
i also made change in Makefile.common in main folder.

Re: [Discuss-gnuradio] How to link gnuradio library with applications outside of gnuradio/usrp?
Hi Marcus M (cool name, actually), gr_complex is an STL complexfloat, so you won't need the complete GR core to use it: gnuradio-core/src/lib/runtime/gr_complex.h:typedef std::complexfloatgr_complex; gri_fft requires only gr_complex (see above) and gr_sys_paths, which is essentially replaceable by string literals. (and boost filesystemthreads 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.

This is weird to me. Well, if it really is configured for a static IP, you might see if there's a way to force the card to only use 1GiGe. I don't know how to do that in windows, but I do know that some 1GiGe PHY implementations don't auto-negotiate properly, so if you can force the ethernet hardware to run always at 1GiGe, and not auto-speed negotiate, that sometimes helps. -- Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
