Hi out there, Again the bundle of gr, bladerf, gr-osmosdr/iqbal, libusbx and gqrx do not fit together. After updating bladerf gqrx does not start any more, giving this error: gr-osmosdr v0.1.0-46-g05d51b53 (0.1.1git) gnuradio v3.7.2.1-86-g324cdab6 built-in source types: file bladerf Using Volk machine: avx\_32\_mmx\_orc gr-osmosdr v0.1.0-46-g05d51b53 (0.1.1git) gnuradio v3.7.2.1-86-g324cdab6 built-in source types: file bladerf gqrx/gqrx: symbol lookup error: /usr/local/lib/libbladeRF.so.0: undefined symbol: libusb\_get\_version ras@ubuntu:~$ So I removed everything but gnuradio and built/installed it all from scratch again. libusbx, bladerf, gr-osmosdr/Iqbal, gqrx - when building gqrx, it fails with this one: g++ -Wl,-O1 -o gqrx main.o mainwindow.o receiver.o remote\_control.o remote\_control\_settings.o cafsk12.o costabf.o agc\_impl.o correct\_iq\_cc.o lpf.o resampler\_xx.o rx\_demod\_am.o rx\_demod\_fm.o rx\_fft.o rx\_filter.o rx\_meter.o rx\_agc\_xx.o rx\_noise\_blanker\_cc.o sniffer\_f.o stereo\_demod.o udp\_sink\_f.o afsk1200win.o agc\_options.o audio\_options.o demod\_options.o dockinputctl.o dockaudio.o dockfft.o dockiqplayer.o dockrxopt.o freqctrl.o ioconfig.o meter.o nb\_options.o plotter.o qtcolorpicker.o nbrx.o receiver\_base.o wfmrx.o pa\_device\_list.o pa\_sink.o pa\_source.o moc\_mainwindow.o moc\_remote\_control.o moc\_remote\_control\_settings.o moc\_cafsk12.o moc\_afsk1200win.o moc\_agc\_options.o moc\_audio\_options.o moc\_demod\_options.o moc\_dockaudio.o moc\_dockfft.o moc\_dockinputctl.o moc\_dockiqplayer.o moc\_dockrxopt.o moc\_freqctrl.o moc\_ioconfig.o moc\_meter.o moc\_nb\_options.o moc\_plotter.o moc\_qtcolorpicker.o qrc\_icons.o -L/usr/lib/i386-linux-gnu -lboost\_system -lboost\_program\_options -lrt -lpulse-simple -lpulse -L/usr/local/lib -lgnuradio-analog -lgnuradio-filter -lgnuradio-fft -lgnuradio-osmosdr -lgnuradio-blocks -lgnuradio-runtime -lgnuradio-pmt -lQtSvg -lQtGui -lQtNetwork -lQtCore -lpthread /usr/local/lib/libbladeRF.so.0: undefined reference to `libusb\_get\_version’ collect2: ld returned 1 exit status make: \*\*\* [gqrx] Error 1 ras@ubuntu:~/gqrx$ Any ideas?

Hi Ralph, libusb\_get\_version() was added I believe around 1.0.10? It’s wrapped in a logging enabled flag so if you disable logging then maybe it will get past it: [bladeRF/host/libraries/libbladeRF/src/backend/libusb.c at 009d8181e0799f3b8e282e22f6ac793ac9b85f85 · Nuand/bladeRF · GitHub](https://github.com/Nuand/bladeRF/blob/009d8181e0799f3b8e282e22f6ac793ac9b85f85/host/libraries/libbladeRF/src/backend/libusb.c#L525) I’ll take a look at how we can help fix that on our end. Try updating libusb(x) in the meantime? Brian On Fri, Dec 13, 2013 at 12:25 PM, Ralph A. Schmid, dk5ras
