Hi, I'm running a RTL-SDR over a Raspberry Pi. On my old machine everthing worked fine. But now I had to move to another machine and I'm getting this output everytime I start my programm: linux; GNU C++ version 4.7.2; Boost_104900; UHD_003.007.002-0-unknown Warning: failed to XInitThreads() Gtk-Message: Failed to load module "canberra-gtk-module" Using Volk machine: avx_64_mmx_orc gr-osmosdr 0.1.3 (0.1.3) gnuradio 3.7.5 built-in source types: file osmosdr fcd rtl rtl_tcp uhd miri hackrf bladerf rfspace airspy Segmentation fault I have installed GNU Radio with the build-gnuradio script. So everthing should be installed correctly. Thank you for your help! Björn
