Re: [Discuss-gnuradio] Undefined reference to `gr::blocks::vector_source_b::make()'
Thanks Martin, you're right, it's about linking gnuradio-blocks libraries. To make it easy, I've regenerated my project (for Eclipse CDT4), and when I took the time to read what cmake outputs, I found that he actually didn't check for gnuradio-blocks, though he successfully found the others: runtime, filter and fft: Checking for GNU Radio Module: RUNTIME -- checking for module 'gnuradio-runtime' -- found gnuradio-runtime, version 3.7.5 * INCLUDES=/usr/local/include * LIBS=/usr/local/lib/libgnuradio-runtime.so;/usr/local/lib/libgnuradio-pmt.so -- Found GNURADIO_RUNTIME: /usr/local/lib/libgnuradio-runtime.so;/usr/local/lib/libgnuradio-pmt.so GNURADIO_RUNTIME_FOUND = TRUE Checking for GNU Radio Module: FFT -- checking for module 'gnuradio-fft' -- found gnuradio-fft, version 3.7.5 * INCLUDES=/usr/local/include * LIBS=/usr/local/lib/libgnuradio-fft.so;/usr/local/lib/libgnuradio-runtime.so;/usr/local/lib/libgnuradio-pmt.so -- Found GNURADIO_FFT: /usr/local/lib/libgnuradio-fft.so;/usr/local/lib/libgnuradio-runtime.so;/usr/local/lib/libgnuradio-pmt.so GNURADIO_FFT_FOUND = TRUE Checking for GNU Radio Module: FILTER -- checking for module 'gnuradio-filter' -- found gnuradio-filter, version 3.7.5 * INCLUDES=/usr/local/include * LIBS=/usr/local/lib/libgnuradio-filter.so;/usr/local/lib/libgnuradio-fft.so;/usr/local/lib/libgnuradio-runtime.so;/usr/local/lib/libgnuradio-pmt.so -- Found GNURADIO_FILTER: /usr/local/lib/libgnuradio-filter.so;/usr/local/lib/libgnuradio-fft.so;/usr/local/lib/libgnuradio-runtime.so;/usr/local/lib/libgnuradio-pmt.so GNURADIO_FILTER_FOUND = TRUE -- I really don't know what I've missed ?

Hi there, I'm working on my OOT with gnuradio 3.7.5 on ubuntu 14.04.2 LTS.

I did add gr::blocks headers and libraries in myootroot/CMakeLists.txt and myootroot/lib/CMakeLists.txt, but in vain.

GNU Radio does not care the slightest about how high your sampling rate is. Some blocks need this information to calculate relative frequence (ie. frequencies related to the unit sample), but there is absolutely no restriction that links your theoretical sampling rate to your processing speed. If you start using hardware, then, of course, you'll have to make sure that a) your sampling rate matches your application and your hardware and b) your computer is able to process the samples fast enough to keep everything running in real time.
